2. Description of the Related Art Secosteroids are well known to those skilled in the art, see J. Chem. Soc. Chem. Commun., 709 (1982), ibid 1096 (1983) and Tetrahed¬ ron 2, 80 (1958). However, none of the prior art secosteroids contain an amine functionality at the ^ter xmal position of the C_ side chain. Further, none of these secosteroids is useful in treating, head injury, spinal cord trauma or stroke. Published PCT patent application Serial No 86/01797 discloses amino steroids where the- amine portion includes acyclic, aromatic and heterocyclic amine functionality very similar to the amino sub- stituents of the present invention. In published PCT patent applica¬ tion Serial No 86/01797, the amino substituent was attached to the terminal carbon atom of the steroidal C_ side chain. The present invention differs from Published PCT patent application Serial No 86/01797 in that the non-amine portion is not a steroid. Published PCT patent application Serial No 86/01797 also disclosed numerous references involving various amines and amino substituents which are incorporated here by reference. Published PCT patent application Serial No 86/01797 is the reference which discloses amino sub¬ stituents most similar to those of the present invention.

German Patent 1,087,598 and US Patent 2,920,999 disclose simple 21-amino derivatives of Δ -3-keto steroids. The amines include both mono and bis substituted amines. In the cases where the amino group is disubstituted, the two substituents can be cyclized with the attached nitrogen atom to form a heterocyclic amino group (mor- pholine, pyrrolidine, piperidine, pyridine) . The amines were chosen from the group consisting of amino, monoalkylamino, dialkylamino, phenylamino, pyridylamino, benzylamino, picolinylamino, N-alkyl-N- phenylamino, N-alkyl-N-pyridylamino, morpholinyl, pyrryl, pyrrolidyl, piperidino and C-alkylated piperidino, though only N-piperidino, N,N- diethyl and N-me hyl-N-phenyl were exemplified.

DETAILED DESCRIPTION OF THE INVENTION The amino-9,10-secosteroids (I), also known as octahydro indenones or indenes, of the present invention can be thought of as being made of two parts, an amine portion and a secosteroid portion. The desired amino-9,10-secosteroids (I) are preferably prepared by condensing the desired amine portion with the desired secosteroid portion. The preferred amino-9,10-secosteroids (I) have a keto func¬ tionality at what is C__ of a steroid. Therefore, one either starts with a 11-keto steroid (corticoid or non-corticoid) or the cor¬ responding llα- or 110-hydroxy steroid, and oxidizes it to the cor¬ responding 11-keto steroid by methods well known to those skilled in the art, preferably pyridinium chlorochromate/sodium acetate in a solvent such as methylene chloride; see, EXAMPLE 2. EXAMPLE 1 demonstrates one convenient method to protect the 17α- and 21-hydroxy groups during the oxidation of the secondary alcohol at C\ .

The intact Δ ^1, -3-keto steroid starting material is then converted to a secosteroid by methods well known to those skilled in the art, see for example J. Chem. Soc. Chem. Commun., 709 (1982), ibid 1096 (1983) and Tetrahedron 2, 80 (1958). Preferred is the process using lithium and ammonia in THF; see, EXAMPLE 3. The free

hydroxyl groups of the C ₇ -side chain may be appropriately protected as determined and by procedures known to those skilled in the art. If a "Δ^CH)"-secosteroid is desired then it is preferable to use samarium iodide or n-tributyl tin hydride on the xanthate ester of an 11-hydroxy steroid.

Next, the hydroxyl group at the C5 position of the secosteroid (C3 of a steroid) is optionally protected by methods well known to those skilled in the art, for example as the benzyl ether; see, EXAMPLE 4. Next, the protecting groups on the C_ _j side chain are removed by methods well known to those skilled in the art appropriate for the particular protecting group. For example, if there are hydroxy groups at 17 and 21 of the corticoid type starting material, and they are protected as the ace onide, this group is readily removed by acid as is well known to those skilled in the art, see EXAMPLE 5. This is done so as to be able to functionalize the position to which the amine will attach with a good leaving group such as tosylate, mesylate, chloride, bromide, iodide, and equivalents thereof, see EXAMPLE 6. Next what corresponds to the "21-position ^B of the parent steroid is converted from a hydroxy functionality to a good leaving group such as chloride and/or tosylate. The use of p-toluenesulfonyl chloride produces both the chloro and tosyl derivatives. This mixture can be separated if desired. However, since both react with the amines to produce the desired amino-9,10-secosteroids (I), it is preferred to react the mixture of chloro and tosyl derivatives. Alternatively and preferably the leaving group, when chloride, can be introduced by use of triphenylphosphine and carbon tetrachloride, see EXAMPLE 15. The desired secosteroid with a good leaving group in the position to which it is desired to attach the amine, and the desired amine are condensed in an aprotic solvent such as acetonitrile, DMF, THF, methylene chloride, DMA, ether and the like containing a base. It is preferred that the solvent be DMF or if a mixture, contain a high % of DMF. It is further preferred that the condensation take place in the presence of an iodide, such as sodium or potassium. Suitable bases include carbonate, bicarbonate, triethylamine, diisopropylethylamine and the like.

Last, any remaining protecting groups removable by hydrogenoly¬ sis are removed by methods well known to those skilled in the art; see EXAMPLES 8, 10 and 12 to produce the desired amino-9,10-seco¬ steroid (I) . Alternatively, cyclohexadiene can be used in place o cyclohexene.

If it is desired that R^χ be α-H: ?-0H or α-0H: -H, the compoun where R^χ is -0 is reduced with sodium borohydride or lithiu selectride. Further, if it is desired that there be a double bond in the position C9 to C__ of the parent steroid (one of R9.1 or R9.2 are taken together with one of n- _] _ and n-2 to form a second bond between C9 and C__) the 11-hydroxy form is dehydrated by means well known to those skilled in the art or preferably one forms the Δ 'H' double bond when one transforms the steroid to the secosteroid by the process disclosed in J. Chem. Soc. Chem. Commun., 709 (1982). If it is desired that the substituent at C_ _a be -H rather than -OH, the hydroxyl group can be removed by reaction with TMS-I (trimeth lsil l iodide). This can be done before or after the steroid is converted to the secosteroid, preferably before.

It is preferred that the condensation of the amine and secos- teroid be the desired amine and desired secosteroid with the excep¬ tion of readily removable protecting groups. Alternatively, in principle, a (derivative) form of the secosteroid not necessarily desired as the final product (I) , can be reacted in its ^c terminal 21-halo, 21mesylate or 21- osylate form with the appropriate amine to afford an amino-9,10-secosteroid. Following this, the secosteroid nucleus itself can be modified to produce the desired amino-9,10- secosteroid (I). While this is an alternative process, in principle, to produce the amino-9,10-secosteroids (I) of the present invention, in practice it is an undesirable method compared to the preferred process of reacting the C _term χ _na halo, tosyl or mesyl analog corre¬ sponding to the secosteroid portion of desired amino-9,10-seco¬ steroids (I) , with an amine corresponding to the amine portion of the desired amino-9,10-secosteroids (I) as is apparent to one skilled in the art. Yet another alternative procedure, in principle, to produce some of the amino-9,10-secosteroids (I) of the invention which involve amino substituents which can be thought of as having 2 or more components, can be produced by first reacting the halo, tosyl or

mesyl secosteroid with a portion of the desired amine substituent to form an aminosecosteroid in which there is an amine substituent at the C _termj _ _na -position followed by further reaction of the amino portion of the amino-9,10-secosteroid to produce the complete amine substituent at the C _term χ _na position. While this is an alternative process in principle, in practice it is usually undesirable compared to the preferred process.

It is preferred that the R3 group is -H, acetyl or benzyl. It is more preferred that R3 be -H. In what is known to those skilled in the art as the C-ring of a steroid, the substitution includes 11-keto, Δ' ϋ), and 11- (a/β) - hydroxy. It is preferred that the substitution be 11-keto.

With the Δ^°-9,10-secos eroid (I), it is preferred that the sub¬ stituent at C__ be -H. With the other 9,10-secosteroids (I) having two substituents at C _s it is preferred that the substituent be either two -H's or a -H and a -CH3. If -CH3, it is preferred that it be in the a configuration.

It is preferred that the side chain at C_η be -C(-Z)-(CH2) _n -N- 21A 21B- ^{c s} preferred that Z is -0 or -H,-H, it is more prefer- red that Z is -0. It is preferred that n is 1.

It is more preferred that the heterocyclic ring be 1-piperazinyl substituted in the -position with - (CR_) -hetero¬ aryl. It is preferred that j is 0.

The amino -9, 10 -secosteroids (I) of the present invention are reacted with acids to form amine salts by methods known to those skilled in the art and the resulting salts are more water soluble and

therefore preferable to use when an aqueous formulation is desire such as a solution for IV use. Generally the __nino-9 , 10-secosteroid (I) possess one or more basic nitrogen atoms to be converted to a acid addition pharmaceutically acceptable salt. However, when n is 0 and Z is -0 and the compound does not contain another nitrogen atom, they will not form salts suitable as pharmaceuticals. The pharm¬ aceutically acceptable salt forms of the amino substituted steroids (I) are generally preferred over the free base form since the salts have greater water solubility and form crystals more suitable for pharmaceutical purposes. An acid addition salt of the amino-9,10- secosteroids (I) can be converted to the free base, which can be converted to any desired pharmaceutically acceptable acid addition salt by methods known to those skilled in the art. It is preferred that the acid addition salt be prepared by reacting the free base of the amino -9, 10 -secosteroids (I) with an approximately stoichiometric amount of an acid, such as hydrochloric, hydrobromic, hydroiodic, sulfuric, phosphoric, acetic, lactic, citric, succinic, benzoic, salicylic, pamoic, cyclohexanesulf mic , aethanesulf onic , naph¬ tha lenesulfonic , p-toluenesulfonic, maleic, fu aric, oxalic acid and the like.„ It is preferred that the acid be selected from the group consisting of hydrochloric, maleic, methanesulfonic and fumaric acids.

The amino- 9, 10- secosteroids (I) and acid addition salts thereof can be isolated as hydrates or solvates, and such forms are regarded as equivalent to the corresponding amino -9, 10- secosteroids (I) not containing water or solvent.

The amino-9,10-secosteroids (I) of the present invention are useful pharmaceutical agents in treating a number of different medical conditions in humans and useful warm blooded animals . In humans, the amino -9, 10 -secosteroids (I) of the present invention are useful in treating spinal trauma, mild and/or moderate to severe head injury, subarachnoid hemorrhage and subsequent cerebral vasospasm, ischemic (thromboembolic) stroke, excess mucous secretion, asthma, muscular dystrophy, adriamycin- induced cardiac toxicity, adriamycin induced cytotoxicity during anti-cancer therapy, Parkinsonism, Alzheimer's disease, other degenerative neurological disorders, multiple sclerosis, organ damage during reperfusion after transplant, skin graft rejection, hemorrhagic, traumatic and septic

shock, and conditions such as severe burns, ARDS, inflammatory diseases such as osteo- or rheumatoid arthritis, nephrotic syndrome (immunological) , systemic lupus erythematosis, allergic reactions, atherosclerosis, inflammation (for example dermatological, in- flammatory and psoriasis conditions), emphysema, stress induced ulcers, cluster headaches, complications from brain tumors, radiation damage and damage after MI, infant hypoxia syndrome and such opthai- mic disorders such as uveitis and optic neuritis.

In humans, the amino-9,10-secosteroids (I) are useful in preventing damage following cardiopulmonary resuscitation, neurolo¬ gical or cardiovascular surgery and from cardiac infarction.

The amino-9,10-secosteroids (I) are useful for reducing the side effects of the tetracycline anti-neoplastic agents such as adriamycin and daunomycin. Generally, the amino-9,10-secosteroids (I) are useful in the same way as glucocorticoid pharmaceuticals for the treatment of the above human conditions as well as the animal conditions listed below. While the amino-9,10-secosteroids (I) are useful in both humans and animals in treating many of the same conditions and preventing damage from the same problems as the glucocorticoids, the amino-9,10-secosteroids (I) are useful- in treating a number of conditions and preventing damage from conditions where the glucocor¬ ticoids are not useful. The amino-9,10-secosteroids (I) have no glucocorticoid activity and therefore, unlike the glucocorticoids, they can be given daily for long periods of time (used chronically) without the side effects associated with the glucocorticoids. This is a distinct advantage.

It is to be understood that each of the amino-9,10-secosteroids (I) is useful to a different degree for treating each of the condi- tions above. However, as is known to those skilled in the art, some of the amino-9,10-secosteroids (I) are better for treating some conditions and others are better for treating other conditions. In order to determine which compounds are better than others for a particular condition one can utilize known tests that do not require experimentation but only routine analysis.

For example, the fertile egg or chick embryo assay of Folkman, Nature 288, 551 (1980) or Science 221, 719 (1983), discloses an assay to determine antiangiogenie activity which is indicative of irihibi-

tion of tumor growth and anti-cancer utility. Because of the abilit of the compounds which are active in the Folkman embryo test t inhibit tumor growth, ^' they are useful in the treatment of variou diseases and conditions, especially various forms of cancer Accordingly, they are administered to animals and humans to prolon survival or reduce pain and/or discomfort secondary to tumor growt and the alike. Further, the arachidontic acid LD50 test of Kohler Thrombosis Res., 9, 67 (1976), identifies compounds which ar antioxidants, which inhibit lipid peroxidation, and/or which inhibi the prostaglandin cascade and are useful in treating spinal trauma, mild and/or moderate to severe head injury, degenerative neurologica disorders, etc. Another method useful for determining which par¬ ticular compounds inhibit lipid peroxidation and which are therefor useful in treating spinal trauma, mild and/or moderate to severe hea injury, degenerative neurological disorders, etc is described b Pryor in Methods of Enzymology 105, 293 (1984). Further, the mous head injury assay of Hall, J. Neurosurg. , 62, 882 (1980) discloses a assay from which one skilled in the art can readily determine whic particular amino-9,10-secosterords (I) are useful in the acute treatment of spinal trauma or mild and/or moderate to severe hea injury. Additionally, the cat 48 hr motor nerve degeneration model of Hall et al, Exp. Neurol., 79, 488 (1983) discloses a routine assay from which one skilled in the art can readily determine which particular amino-9,10-secosteroids (I) are useful in treating chronic degenerative neurological disorders such as Parkinsonism, Alzheimer's disease etc. H. Johnson in Int. Arch. Allergy Appl. Immunol., 70, 169 (1983) has described the ascaris sensitized rhesus monkey assay for anti-asthma drugs.

The standard conditions for treatment are to give the amino- 9,10-secosteroids (I) orally or parenterally, e.g. IV (that is by injection, infusion or continuous drip) or IM, with a standard dose of about 0.05 to about 100 mg/kg/day, one to four times daily.

For treating spinal trauma, mild and moderate to severe head injury, damage following cardiopulmonary resuscitation, cardiac infarction, organ damage during reperfusion after transplant, hemor- rhagic, traumatic and septic shock, severe burns, ARDS, and nephrotic syndrome and preventing skin graft rejection, the standard conditions are used. Typical treatment will involve an initial loading dose,

e.g. an IV dose of 0.01 mg to 1 mg/kg followed by maintenance dosing e.g. IV infusion for a day to a week depending on the particular condition of the patient and the particular compound used. This may be supplemented with IM or oral dosing for days, weeks or months to prevent delayed neuronal degeneration in neurological applications (eg spinal trauma, head injury).

In treating subarachnoid hemorrhage and subsequent cerebral vasospasm or ischemic (thromboembolic) stroke the standard conditions are used and patients at risk are pre-treated orally. In treating excess mucous secretion and asthma the amino-9,10- secosteroids (I) are administered orally, IV and by inhalation in the standard dose. In treating excess mucous secretions the dose of the amino-9,10-secosteroids (I) used is from about 0.05 to about 100 mg/kg/day. The frequency of administration is one through 4 times daily. The oral administration of the amino-9,10-secosteroids (I) to treat excess mucous secretions may go on for months or even years. The susceptible individuals can be pre-treated a few hours before an expected problem. The IV dose is about 0.05 to about 50 mg/kg/day. The aerosol formulation contains about 0.05 to about 1.0% of the amino-9,10-secosteroids (I) and is administered or used about four times daily as needed.

In treating cancer, muscular dystrophy, Parkinsonism, Alz¬ heimer's disease and other degenerative neurological disorders (amyotrophic lateral sclerosis; multiple sclerosis) the amino-9,10- secosteroids (I) are administered orally using a dose of about 0.05 to about 100 mg/kg/day, administered or used one to four times a day. The treatment may go on for years.

In addition, utility in cancer as well as other disorders or physiological phenomena dependent on angiogenesis or neovasculariza- tion such as embryo implantation (antifertility), arthritis, and atherosclerosis is exhibited with the amino-9,10-secosteroids (I) with or without co-administered oral heparin or systemic heparin fragments, see Science 221, 719 (1983).

In treating adriamycin-induced cardiac toxicity and cytotoxicity during anti-cancer therapy the amino-9,10-secosteroids (I) are administered orally or IV using a dose of about 0.05 to about 100 mg/kg/day, preferably about 0.5 to about 10 mg/kg/day. The amino- 9,10-secosteroids (I) are preferably given concomitantly with IV

adriamycin or the individual is pre-treated with the amino-9,10- secosteroids (I) .

For prophylaxis prior to and preventing damage after neurologi¬ cal or cardiovascular surgery the amino-9,10-secosteroids (I) are used according to the standard conditions. The patient can be pretreated with a single IV or IM dose just prior to surgery or orally before and after surgery.

In treating osteo- or rheumatoid arthritis and other inflam¬ matory diseases the amino-9,10-secosteroids (I) are given orally or IM in doses of about 0.05 to about 100 mg/kg/day, one to four times daily. Orally the drug will be given over a period of months or years alone or with other steroidal agents. The initial dose with some severe rheumatoid patients may be given IV and followed with an IV drip for up to 24 hr or more. In .addition, intra- rterial administration may be employed.

In treating drug allergic reactions the amino-9,10-secosteroids

(I) are given in a dose of about 0.05 to 100 mg/kg/day, administered one to four times daily orally and IV. Typical treatment would be an initial IV loading dose followed by oral dosing for a few days or more.

In treating atherosclerosis and emphysema the amino-9,10- secosteroids (I) are given orally in a dose of about 0.05 to about 100 mg/kg/day, one to four times daily for months or years.

In treating dermatological inflammatory conditions including psoriasis the amino-9,10-secosteroids (I) are given orally in a dose of about 0.05 to about 100 mg/kg/day, one to four times daily or applied topically as a cream, ointment or lotion or equivalent dosage form in a concentration of about 0.05 to about 5% as long as needed. In treating these conditions the amino-9,10-secosteroids (I) can be used with steroidal agents.

In treating Alzheimer's disease the amino-9,10-secosteroids (I) are given orally in a dose of about 1 to about 100 mg/kg/day, one to four times daily.

The amino-9,10-secosteroids (I) are useful in the prevention and treatment of stress ulcers and of gastric intolerance caused by drugs such as nonsteroidal anti-inflammatory compounds (NOSAIDS). Stress ulcers are ulcers that develop after exposure to severe conditions such as trauma, burns, sepsis, extensive surgery, acute illnesses,

and the like. Patients in intensive care units are particularly prone to develop stress ulcers. Stress ulcers also include lesions that can lead to upper gastrointestinal bleeding; such bleeding is likely to be prevented or stopped by these compounds. NOSAC includes drugs such as ibuprofen, aspirin, indomethacin, naproxen, piroxicam and the like that are usually taken for analgesia, and that are often associated with gastrointestinal intolerance characterized by pain and lesions that may lead to bleeding. The amino-9,10-secosteroids (I) will be administered preferentially by the oral route either as tablets, capsules or liquids, in doses ranging from 5 to 500 mg, two to four times a day. The treatment would be either preventive, i.e., starting before ulcers have formed in patients at risk of developing such lesions, or therapeutic, i.e., after the ulcers have formed. In patients whose clinical condition precludes swallowing the oral dosage forms, the amino-9,10-secosteroids (I) would be given either through a nasogastric tube, or parenterally, i.e., IV or IM. The parenteral doses would range from about 1 to about 100 mg and be administered one to four times a day or by IV.

In dogs, the amino-9,10-secosteroids (I) are useful in treating head and spinal trauma, intervertebral diseases (slipped disk) , traumatic shock, flea bite and other allergies.

In horses, the amino-9,10-secosteroids (I) are useful in treating endotoxic or septic shock which follows colic, pretreatment before surgery for colic and treatment of Founder (la initis) . In cattle, the amino-9,10-secosteroids (I) are useful in treating acute coliform mastitis, bovine mastitis and acute allergic reaction to feed lot vaccination.

In pigs, the amlno-9,10-secosteroids (I) are useful in treating porcine stress syndrome and thermal stress syndrome. The term treatment or treating as used in this patent is used broadly and includes both treatment of an existing condition as well as preventing the same condition from occurring where such is possible as Is well known to those skilled in the art. For example, the amino-9,10-secosteroids (I) can be used to treat existing asthma conditions and to prevent future ones from occurring. For example, the amino-9,10-secosteroids (I) treat spinal trauma and prevent rejection of skin grafts.

The amino-9,10-secosteroids (I) can be used with other phar-

maceutical agents in treatment of the conditions listed above as is known to those skilled in the art.

The exact dosage and frequency of administration depends on the particular amino-9,10-secosteroids (I) used, the particular condition being treated, the severity of the condition being treated, the age, weight, general physical condition of the particular patient, other medication the individual may be taking as is well known to those skilled in the art and can be more accurately determined by measuring the blood level or concentration of the amino-9,10-secosteroids (I) in the patient's blood and/or the patients response to the particular condition being treated.

DEFINITIONS AND CONVENTIONS The definitions and explanations below are for the terms as used throughout this entire document including both the specification and the claims.

I. CONVENTIONS FOR FORMULAS AND DEFINITIONS OF VARIABLES The chemical formulas representing various compounds or molecu¬ lar fragments in the specification and claims may contain variable substituents in addition to expressly defined structural features. These variable substituents are identified by a letter or a letter followed by a numerical subscript, for example, "Zχ ^B or ^π Rχ ^B where "i" is an integer. These variable substituents are either monovalent or bivalent, that is, they represent a group attached to the formula by one or two chemical bonds. For example, a group Z_ would repres- ent a bivalent variable if attached to the formula CH3-C(-Zχ)H. Groups Rx and R-; would represent monovalent variable substituents if attached to the formula CH3-CH2"C(Rχ)(R*)H2> When chemical formulas are drawn in a linear fashion, such as those above, variable sub¬ stituents contained in parentheses are bonded to the atom immediately to the left of the variable substituent enclosed in parenthesis. When two or more consecutive variable substituents are enclosed in parentheses, each of the consecutive variable substituents is bonded to the immediately preceding atom to the left which is not enclosed in parentheses. Thus, in the formula above, both Rx and R.s are bonded to the preceding carbon atom. Also, for any molecule with an established system of carbon atom numbering, such as steroids, these carbon atoms are designated as Cx, where "i" is the integer cor¬ responding to the carbon atom number. For example, Cg represents the

65 position or carbon atom number In the compound nucleus as tradi¬ tionally designated by those skilled in the art of that chemistry. Likewise the term "Rg" represents a variable substituent (either monovalent or bivalent) at the Cg position. 5 Chemical formulas or portions thereof drawn in a linear fashion represent atoms In a linear chain. The symbol "-" in general represents a bond between two atoms in the chain. Thus CH3-O-CH2- CH( £)-CH3 represents a 2-substituted-l-methoxypropane compound. In a_ similar fashion, the symbol "-" represents a double bond, e.g., D3 C5_2-C(Rχ)-0-CH3, and the symbol "-" represents a triple bond, e.g., HC«C;-CH(Rχ)-CH2-CH3. Carbonyl groups are represented in either one of" ^" two ways: -CO- or -C(-O)-, with the former being preferred for simplicity.

Chemical formulas of cyclic (ring) compounds or molecular 5 fragments can be represented in a linear fashion. Thus, the compound 4-chloro-2-methylpyridine can be represented in linear fashion by N*-C(CH3)-CH-CC1-CH-C*H with the convention that the atoms marked with an asterisk (*) are bonded to each other resulting in the formation of a ring. Likewise, the cyclic molecular fragment, 4- 0 (ethyl)-1-piperazinyl can be represented by -N*-(CH2)2- (C2H5 -CH2- C*H ₂ .

A cyclic (ring) structure for any compound herein defines an orientation with respect to the plane of the ring for substituents attached to each carbon atom of the cyclic compound. In formulas 5 depicting such compounds, a substituent attached to a carbon atom bύe-lZαsr the plane of the ring is Identified as being in the alpha (α) cunflgciration and Is indicated by a broken, dashed or dotted line attachment to the carbon atom, i.e., by the symbol ⁿ - - -" or ^m . *. The corresponding substituent attached above the plane of £ the ring is identified as being in the beta ( _/ 5) configuration. When a variable substituent is bivalent, the valences may be taken together or separately or both in the definition of the variable. For example, a variable R_ attached to a carbon atom as -C(—R^ - might be bivalent and be defined as oxo or keto (thus forming a 5 carbonyl group (-C0-) or as two separately attached monovalent variable substituents t-Rχjj and _/ 5-Rχ^-. When a bivalent variable, R^, is defined to consist of two monovalent variable substituents, the convention used to define the bivalent variable is of the form "α-

or some variant thereof. In such a case both α- ^R χj and β- Rχi- are attached to the carbon atom to yield -C(α-Rχj) ( -Rχj-)- • For example, when the bivalent variable Rg, -C(-Rg)-, (at Cg) is defined to consist of two monovalent variable substituents, two monovalent variable substituents are α-Rg_χ:j8-Rg_2> •••• ^α - ^R 6-9 ^: "" ^R 6-10> ^etc > yielding -C( -Rg.χ)09-Rg. ₂ )- -C(α-R _ ₉ ) (y3-R .χ ₀ )- , etc.

Likewise, for the bivalent variable Rχχ _> -C(-Rχχ)-, (at __) two monovalent variable substituents are α- ^R χχ.χ:3-Rχχ_2- ^{or a r} i ⁿ S substituent for which separate α and β orientations do not exist (e.g. due to the presence of a carbon carbon double bond in the ring) , and for a substituent bonded to a carbon atom which is not part of a ring the above convention is still used, but the and β designations are omitted.

Just as a bivalent variable may be defined as two separate monovalent variable substituents, two separate monovalent variable substituents may be defined to be taken together to form a bivalent variable. For example, in the formula -Cχ(Rχ)H-C2(Rj)H- (0χ and C2 define arbitrarily a first and second carbon atom, respectively) Rx and R< may be defined to be taken together to form (1) a second bond between C_ and C2 or (2) a bivalent group such as oxa (-0-) and the formula thereby describes an epoxide. When R_ and Ri are taken together to form a more complex entity, such as the group -X-Y- , then the orientation of the entity is such that C_ in the above formula is bonded to X and C2 is bonded to Y. Thus, by convention the designa- tion "... Rx and Rj are taken together to form -CH ₂ -CH ₂ -0-CO- ..." means a lactone in which the carbonyl is bonded to C2. However, when designated "... Rj and R are taken together to form -CH2-CH2-O-CO- the convention means a lactone in which the carbonyl is bonded to C_ .

The carbon atom content of variable substituents is indicated in one of two ways. The first method uses a prefix to the entire name of the variable such as "Cχ-C4", where both "1" and "4" are integers representing the minimum and maximum number of carbon atoms in the variable. The prefix is separated from the variable by a space. For example, "Cχ-C alkyl" represents alkyl of 1 through 4 carbon atoms, (including isomeric forms thereof unless an express indication to the contrary is given) . Whenever this single prefix is given, the prefix indicates the entire carbon atom content of the variable being defined. Thus C2-C4 alkoxycarbonyl describes a group CH3-(CH ₂ ) _n -0-

CO- where n is zero, one or 2. By the second method the carbon atom content of only each portion of the definition is Indicated separate¬ ly by enclosing the "Ci-Cj" designation in parentheses and placing it Immediately (no Intervening space) before the portion of the defini- tion being defined. By this optional convention (0 -C3)alkox - carbonyl has the same meaning as C2-C4 alkoxycarbonyl because the "Cχ-C3" refers only to the carbon atom content of the alkoxy group. Similarly while both C ₂ -Cg alkoxyalkyl and (Cχ-C3)alkoxy(Cχ-C3)alkyl define alkoxyalkyl groups containing from 2 to 6 carbon atoms, the two definitions differ since the former definition allows either the alkoxy or alkyl portion alone to contain 4 or 5 carbon atoms while the latter definition limits either of these groups to 3 carbon atoms.

When the claims contain a fairly complex (cyclic) substituent, at the end of the phrase naming/designating that particular sub¬ stituent will be a notation in (parentheses) which will correspond to the same name/designation in one of the CHARTS which will also set forth the chemical structural formula of that particular substituent.

EXAMPLES Without further elaboration, it is believed that one skilled in the art can, using the preceding description, practice the present invention to its fullest extent. The following detailed examples describe how to prepare the various compounds and/or perform the various processes of the invention and are to be construed as merely illustrative, and not limitations of the preceding disclosure in any way whatsoever. Those skilled in the art will promptly recognize appropriate variations from the procedures both as to reactants and as to reaction conditions and techniques. PREPARATION A-6 4-(2-Pyridinyl)piperazine [34803-66-2], see French Patent 7253 M. PREPARATION A-14 4-[4,6-Bis(2-propenylamino)-l,3,5-triazin-2-yl] - piperazine A solution of 2-chloro-4,6-bis(2-propenylamino)-l,3,5-triazine (10.44 g) and 15.95 g of N-formyl piperazine in 150 ml of DMF is heated under reflux for about 18 hours. The reaction mixture is cooled and stored at 5° and crystals are deposited. The soluble fraction is concentrated and the residue is extracted with ethyl acetate. The extracts are washed with aqueous potassium carbonate, 50% saline, saline and dried over magnesium sulfate and concentrated to give a gum. Chromatography on silica gel (400 g) and elution (200 ml fractions) with 20% acetone-methylene chloride gives the for- mamide. The formamide (9.2 g) in 200 ml of methanol is heated to reflux, then cooled under nitrogen and mixed with 4 ml of 45% potassium hydroxide solution. The mixture is heated under reflux for

about 20 hours, then cooled and concentrated. The residue is partitioned between ethyl acetate and water. The organic extracts are washed with water and saline, dried over magnesium sulfate and concentrated to give a gum. Crystallization from 50 ml of carbon tetrachlbride gives the title compound, πrp 93-94.5".

PREPARATION A-22 4- [ 2 , 6-Bis (1-pyrrolidinyl) -4-pyrimidinyl] - piperazine A solution of pyrrolidine (80 g) in THF (500 ml) is chilled in an ice water bath and stirred mechanically under nitrogen. With a syringe pump of 2,4,6-trichloropyrimidine (50 g) is added over 35 minutes. The reaction is stirred in the ice bath for 1 hour and is then warmed to 20-25° over 4 h.
