Substituted Pyridopyrazines as Syk Inhibitors

TECHNICAL FIELD

[001] The present invention relates to novel pyridopyrazine compounds,

pharmaceutical compositions thereof and methods of use therefore.

BACKGROUND OF THE INVENTION

[002] Protein kinases, the largest family of human enzymes, encompass well over 500 proteins. Spleen Tyrosine Kinase (Syk) is a member of the Syk family of tyrosine kinases, and is a regulator of early B-cell development as well as mature B-cell activation, signaling, and survival.

[003] Syk is a non-receptor tyrosine kinase that plays critical roles in

immunoreceptor- and integrin-mediated signaling in a variety of cell types, including B cells, macrophages, monocytes, mast cells, eosinophils, basophils, neutrophils, dendritic cells, T cells, natural killer cells, platelets, and osteoclasts.

Immunoreceptors as described herein include classical immunoreceptors and immunoreceptor-like molecules. Classical immunoreceptors include B-cell and T-cell antigen receptors as well as various immunoglobulin receptors (Fc receptors).

Immunoreceptor-like molecules are either structurally related to immunoreceptors or participate in similar signal transduction pathways, and are primarily involved in non- adaptive immune functions, including, for example, neutrophil activation, natural killer cell recognition, and osteoclast activity. Integrins are cell surface receptors that play key roles in the control of leukocyte adhesion and activation in both innate and adaptive immunity.

[004] Ligand binding leads to activation of both immunoreceptors and integrins, which results in Src family kinases being activated, and phosphorylation of immunoreceptor tyrosine-based activation motifs (ITAMs) in the cytoplasmic face of receptor-associated transmembrane adaptors. Syk binds to the phosphorylated ITAM motifs of the adaptors, leading to activation of Syk and subsequent

phosphorylation and activation of downstream signaling pathways.

[005] Syk is essential for B-cell activation through B-cell receptor (BCR) signaling. SYK becomes activated upon binding to phosphorylated BCR and thus initiates the early signaling events following BCR activation. B-cell signaling through BCR can lead to a wide range of biological outputs, which in turn depend on the

developmental stage of the B-cell. The magnitude and duration of BCR signals must be precisely regulated. Aberrant BCR-mediated signaling can cause disregulated B- cell activation and/or the formation of pathogenic auto-antibodies leading to multiple autoimmune and/or inflammatory diseases. Mice lacking Syk show impaired maturation of B-cells, diminished immunoglobulin production, compromised T-cell- independent immune responses, and marked attenuation of the sustained calcium sign upon BCR stimulation.

[006] A large body of evidence supports the role of B-cells and the humoral immune system in the pathogenesis of autoimmune and/or inflammatory diseases. Protein- based therapeutics (such as Rituxan) developed to deplete B-cells represent an approach to the treatment of a number of autoimmune and inflammatory diseases. Auto-antibodies and their resulting immune complexes are known to play pathogenic roles in autoimmune disease and/or inflammatory disease. The pathogenic response to these antibodies is dependent on signaling through Fc Receptors, which is, in turn, dependent upon Syk. Because of Syk's role in B-cell activation, as well as FcR dependent signaling, inhibitors of Syk can be useful as inhibitors of B-cell mediated pathogenic activity, including autoantibody production. Therefore, inhibition of Syk enzymatic activity in cells is proposed as a treatment for autoimmune disease through its effects on autoantibody production.

[007] Syk also plays a key role in FCsRI mediated mast cell degranulation and eosinophil activation. Thus, Syk is implicated in allergic disorders including asthma. Syk binds to the phosphorylated gamma chain of FCsRI via its SH2 domains and is essential for downstream signaling. Syk deficient mast cells demonstrate defective degranulation, and arachidonic acid and cytokine secretion. This also has been shown for pharmacologic agents that inhibit Syk activity in mast cells. Syk antisense oligonucleotides inhibit antigen-induced infiltration of eosinophils and neutrophils in an animal model of asthma. Syk deficient eosinophils also show impaired activation in response to FCsRI stimulation. Therefore, small molecule inhibitors of Syk may be useful for treatment of allergy-induced inflammatory diseases including asthma.

[008] Syk is also expressed in mast cells and monocytes and has been shown to be important for the function of these cells. For example, Syk deficiency in mice is associated with impaired IgE-mediated mast cell activation, which causes marked diminution of TNF-alpha and other inflammatory cytokine release. Additionally, Syk inhibitors have been shown to inhibit antigen-induced passive cutaneous anaphylaxsis, bronchoconstriction and bronchial edema in rats.

[009] Thus, the inhibition of Syk activity can be useful for the treatment of allergic disorders, autoimmune diseases, and inflammatory diseases, such as: SLE, rheumatoid arthritis, multiple vasculitides, idiopathic thrombocytopenic purpura (ITP), myasthenia gravis, allergic rhinitis, chronic obstructive pulmonary disease (COPD), adult respiratory distress syndrome (ARDs) and asthma. In addition, Syk has been reported to play an important role in ligand-independent tonic signaling through the B-cell receptor, known to be an important survival signal in B-cells. Thus, inhibition of Syk activity may be useful in treating certain types of cancer, including B-cell lymphoma and leukemia.

[010] Vascular endothelial growth factor (VEGF)-A, a major regulator for

angiogenesis, binds and activates two tyrosine kinase receptors, VEGFR-1 (Flt-1 ) and VEGFR-2 (KDR). VEGFR-1 (Flt-1 )and VEGFR-2 (KDR)play differences in physiological and pathological angiogenesis. VEGFR-2 (KDR)has strong tyrosine kinase activity, andmostly uses the Phospholipase-Cy-Protein kinaseC pathway to activate MAP-kinase and DNA synthesis. VEGFR-2 (KDR)is the major positive signal transducer for both physiological and pathological angiogenesisincluding cancer and diabetic retinopathy.Thus, VEGFR-2 (KDR)kinase inhibitors are being used in the treatment of a wide variety of cancers. Recent studies have shown that patients will likely require long-term treatment with these agents. Hypertension has emerged as a frequent side effect associated with agents that block signaling through the VEGF pathway (Pankaj Bhargava, Am. J. Physiol. Regul. Integr. Comp. Physiol. 297:R1-R5, 2009). Several studies results indicate that the vasodilation and hypotensive effect of VEGF may involve its both receptors, but VEGFR-2 (KDR)is the predominant receptor mediating this effect (Bing Li,efa/., Hypertension.39: 1095-1 100, 2002).

[011] Fms-like tyrosine kinase 3(Flt-3) orreceptor-type tyrosine-protein kinase Flt3 (also known asCluster of differentiation antigen 135, CD135) is acytokine

receptorwhich belongs to the receptor tryrosin kinase class III.FIt-3 is normally expressed by hematopoietic stem/progenitor cells. Signaling through Flt-3 plays a role in cell survival, proliferation, and differentiation. Flt-3 is important for lymphocyte (B cell and T cell) development, but not for the development of other blood cells (myeloid development). Flt-3 knockout mice have a subtle hematopoietic

stem/progenitor cells deficit.Thus, targeted disruption of the Flt-3 gene leads to deficiencies in primitive hematopoietic progenitors.

[016] As used in the present specification, the following words, phrases and symbols are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise. The following abbreviations and terms have the indicated meanings throughout:

[017] A dash ("-") that is not between two letters or symbols is used to indicate a point of attachment for a substituent. For example, -CONH ₂ is attached through the carbon atom.

[018] The term "alkyl" herein refers to a straight or branched hydrocarbon, containing 1-18, preferably 1-12, more preferably 1 -6 carbon atoms. Examples of alkyl groups include, but are not limited to, methyl, ethyl, n-propyl, / ^' -propyl, n-butyl, / ^' - butyl, and i-butyl. "Lower alkyl" refers to a straight or branched hydrocarbon, containing 1-6, preferably 1 -4 carbon atoms.

[019] By "alkoxy" is meant a straight or branched alkyl group containing 1 -18, preferably 1 -12, more preferably 1-6 carbon atoms attached through an oxygen bridge such as, for example, methoxy, ethoxy, propoxy, isopropoxy, n-butoxy, sec- butoxy, tert-butoxy, pentoxy, 2-pentyloxy, isopentoxy, neopentoxy, hexoxy, 2-hexoxy, 3-hexoxy, 3-methylpentoxy, and the like. Alkoxy groups will usually have from 1 to 6 carbon atoms attached through the oxygen bridge. ""Lower alkoxy" refers to a straight or branched alkoxy, wherein the alkyl portion contains 1 -6 , preferably 1 -4 carbon atoms.

[020] The term "alkenyl" herein refers to a straight or branched hydrocarbon, containing one or more C=C double bonds and 2-10, preferably 2-6 carbon atoms. Examples of alkenyl groups include, but are not limited to, vinyl, 2-propenyl, and 2- butenyl.

[021] The term "alkynyl" herein refers to a straight or branched hydrocarbon, containing one or more C≡C triple bonds and 2-10, preferably 2-6 carbon atoms. Examples of alkynyl groups include, but are not limited to, ethynyl, 2-propynyl, and 2- butynyl.

[022] The term "alkylene" herein refers to branched and unbranched alkylene groups with 1 to 6 carbon atoms. Alkylene groups with 1 to 4 carbon atoms are preferred. Examples of these include, but are not limited to: methylene, ethylene, propylene, 1 -methylethylene, butylene, 1-methylpropylene, 1 ,1 -dimethylethylene, 1 ,2-dimethylethylene, pentylene, 1 ,1 -dimethylpropylene, 2,2-dimethylpropylene, 1 ,2- dimethylpropylene, 1 ,3-dimethylpropylene or hexylene. Unless stated otherwise, the definitions propylene, butylene, pentylene and hexylene include all the possible isomeric forms of the groups in question with the same number of carbons. Thus, for example, propylene includes also 1 -methylethylene and butylene includes 1 - methylpropylene, 1 ,1 -dimethylethylene, 1 ,2-dimethylethylene.

[023] The term "cycloalkyl" refers to saturated and partially unsaturated cyclic hydrocarbon groups having 3 to 12, preferably 3 to 8 carbon atoms. Examples of cycloalkyl groups include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclopentenyl, cyclohexyl, cyclohexenyl, cycloheptyl, and cyclooctyl. The ring may be saturated or have one or more double bonds (i.e. partially unsaturated), but not fully conjugated, and not aryl, as defined herein.

[024] "Aryl" encompasses:

5- and 6-membered carbocyclic aromatic rings, for example, benzene;

8- and 12- membered bicyclic ring systems wherein at least one ring is carbocyclic and aromatic, for example, naphthalene, indane, indolinejndolin- 2-one, 2,3-dihydrobenzofuran, benzo[ /][1 ,3]dioxole,and 1 ,2,3,4- tetrahydroquinoline, chroman, 2,3-dihydrobenzo[ib][1 ,4]dioxine, 3,4-dihydro- 2H-benzo[ib][1 ,4]oxazine,isochroman, 1 ,3-dihydroisobenzofuran, 1 H- benzo[d][1 ,3]oxazin-2(4/-/)-one and

1 1- and 14- membered tricyclic ring systems wherein at least one ring is carbocydic and aromatic, for example, fluorene.

For example, aryl includes 5- and 6-membered carbocydic aromatic rings fused to a 5- to 7-membered heterocyclic ring containing one or more heteroatoms selected from N, O, and S, provided that the point of attachment is at the carbocydic aromatic ring. Bivalent radicals formed from substituted benzene derivatives and having the free valences at ring atoms are named as substituted phenylene radicals. Bivalent radicals derived from univalent polycyclic hydrocarbon radicals whose names end in "-yl" by removal of one hydrogen atom from the carbon atom with the free valence are named by adding "-idene" to the name of the corresponding univalent radical, e.g., a naphthyl group with two points of attachment is termed naphthylidene. Aryl, however, does not encompass or overlap in any way with heteroaryl, separately defined below. Hence, if one or more carbocydic aromatic rings are fused with a heterocyclic aromatic ring, the resulting ring system is heteroaryl, not aryl, as defined herein.

[025] The term "halo" includes fluoro, chloro, bromo, and iodo, and the term

"halogen" includes fluorine, chlorine, bromine, and iodine.

[026] The term "heteroaryl" refers to

5- to 8-membered aromatic, monocyclic rings containing one or more, for example, from 1 to 4, or, in some embodiments, from 1 to 3, heteroatoms selected from N, O, and S, with the remaining ring atoms being carbon;

8- to 12-membered bicyclic rings containing one or more, for example, from 1 to 4, or, in some embodiments, from 1 to 3, heteroatoms selected from N, O, and S, with the remaining ring atoms being carbon and wherein at least one heteroatom is present in an aromatic ring; and

1 1- to 14-membered tricyclic rings containing one or more, for example, from 1 to 4, or in some embodiments, from 1 to 3, heteroatoms selected from N, O, and S, with the remaining ring atoms being carbon and wherein at least one heteroatom is present in an aromatic ring.

For example, heteroaryl includes a 5- to 7-membered heterocyclic aromatic ring fused to a 5- to 7-membered cycloalkyl ring. For such fused, bicyclic heteroaryl ring systems wherein only one of the rings contains one or more heteroatoms, the point of attachment is at the heteroaromatic ring.

[027] When the total number of S and O atoms in the heteroaryl group exceeds 1 , those heteroatoms are not adjacent to one another. In some embodiments, the total number of S and O atoms in the heteroaryl group is not more than 2. In some embodiments, the total number of S and O atoms in the aromatic heterocycle is not more than 1 .

[028] Examples of heteroaryl groups include, but are not limited to, (as numbered from the linkage position assigned priority 1 ), 2-pyridyl, 3-pyridyl, 4-pyridyl, 2,3- pyrazinyl, 3,4-pyrazinyl, 2,4-pyrimidinyl, 3,5-pyrimidinyl, 1 -pyrazolyl, 2,3-pyrazolyl, 2,4-imidazolinyl, isoxazolyl, oxazolyl, thiazolyl, thiadiazolyl, tetrazolyl,thienyl, benzothienyl, furyl, benzofuryl, benzoimidazolinyl, indolinyl, pyridizinyl, triazolyl, quinolinyl, pyrazolyl, and 5,6,7,8-tetrahydroisoquinoline.

[029] Bivalent radicals derived from univalent heteroaryl radicals whose names end in "-yl" by removal of one hydrogen atom from the atom with the free valence are named by adding "-idene" to the name of the corresponding univalent radical, e.g., a pyridyl group with two points of attachment is a pyridylidene. Heteroaryl does not encompass or overlap with aryl as defined above.

[030] Substituted heteroaryl also includes ring systems substituted with one or more oxide (-0 ^" ) substituents, such as pyridinyl N-oxides.

[031] By "heterocycle" is meant a 3- to 12-membered (preferably 3- to 8- membered) monocyclic, bicyclic or tricyclic saturated or partially unsaturated ringcontaining at least 2 carbon atoms in addition to 1 -3 heteroatoms independently selected from oxygen, sulfur, and nitrogen. "Heterocycle" also refers to 5- to 7-membered

heterocyclic ring containing one or more heteroatoms selected from N, O, and S fused with 5-,6-, and/or 7-membered cycloalkyl, heterocyclic, carbocyclic aromatic or heteroaromatic ring, provided that the point of attachment is at the heterocyclic ring. "Heterocycle" also refers to an aliphatic spirocyclic ring containing one or more heteroatoms selected from N, O, and S, provided that the point of attachment is at the heterocyclic ring. The rings may be saturated or have one or more double bonds (i.e. partially unsaturated). The heterocycle can be substituted by oxo. The point of the attachment may be carbon or heteroatom in the heterocyclic ring. A heterocyle is not a heteroaryl as defined herein. [032] Suitable heterocycles include, for example (as numbered from the linkage position assigned priority 1 ), 1 -pyrrolidinyl, 2-pyrrolidinyl, 2,4-imidazolidinyl, 2,3- pyrazolidinyl, 1-piperidinyl, 2-piperidinyl, 3-piperidinyl, 4-piperidinyl, and 2,5- piperazinyl. Morpholinyl groups are also contemplated, including 2-morpholinyl and 3-morpholinyl (numbered wherein the oxygen is assigned priority 1 ). Substituted heterocycle also includes ring systems substituted with one or more oxo moieties, such as piperidinyl /V-oxide, morpholinyl-/V-oxide, 1 -oxo-1 -thiomorpholinyl and 1 ,1 - dioxo-1 -thiomorpholinyl.

[033] By "optional" or "optionally" is meant that the subsequently described event or circumstance may or may not occur, and that the description includes instances where the event or circumstance occurs and instances in which it does not. For example, "optionally substituted alkyl" encompasses both "unsubstituted alkyl" and "substituted alkyl" as defined below. It will be understood by those skilled in the art, with respect to any group containing one or more substituents, that such groups are not intended to introduce any substitution or substitution patterns that are sterically impractical, synthetically non-feasible and/or inherently unstable.

[034] The term "substituted", as used herein, means that any one or more

hydrogens on the designated atom or group is replaced with a selection from the indicated group, provided that the designated atom's normal valence is not exceeded. When a substituent is oxo (i.e., =0) then 2 hydrogens on the atom are replaced.

Combinations of substituents and/or variables are permissible only if such

combinations result in stable compounds or useful synthetic intermediates. A stable compound or stable structure is meant to imply a compound that is sufficiently robust to survive isolation from a reaction mixture, and subsequent formulation as an agent having at least practical utility. Unless otherwise specified, substituents are named into the core structure. For example, it is to be understood that when

(cycloalkyl)alkyl is listed as a possible substituent, the point of attachment of this substituent to the core structure is in the alkyl portion.

[035] In some embodiments, "substituted with one or more groups" refers to two hydrogens on the designated atom or group being independently replaced with two selections from the indicated group of substituents. In some embodiments,

"substituted with one or more groups" refers to three hydrogens on the designated atom or group being independently replaced with three selections from the indicated group of substituents. In some embodiments, "substituted with one or more groups" refers to four hydrogens on the designated atom or group being independently replaced with four selections from the indicated group of substituents.

[036] Compounds described herein include, but are not limited to, when possible, to the extent that they can be made by one of ordinary skill without undue

experimentation, their regioisomers, their N-oxide derivatives, their optical isomers, such as enantiomers and diastereomers, mixtures of enantiomers, including racemates, mixtures of diastereomers, and other mixtures thereof, to the extent they can be made by one of oridinary skill in the art by routine experimentation. In those situations, the single enantiomers or diastereomers, i.e., optically active forms, can be obtained by asymmetric synthesis or by resolution of the racemates or mixtures of enantiomers or diastereomers. Resolution of the racemates or mixtures of diastereomers, if possible, can be accomplished, for example, by conventional methods such as crystallization in the presence of a resolving agent, or

chromatography, using, for example a chiral high-pressure liquid chromatography (HPLC) column. In addition, when possible, such compounds include Z- and E- forms (or cis- and trans- forms) of compounds with carbon-carbon double bonds. Where compounds described herein exist in various tautomeric forms, the term "compound" is intended to include, to the extent they can be made without undue experimentation, all tautomeric forms of the compound. Such compounds also include crystal forms including polymorphs and clathrates, to the extent they can be made by one of ordinary skill in the art without undue experimentation. Similarly, the term "salt" is intended to include all isomers, racemates, other mixtures, Z- and E- forms, tautomeric forms and crystal forms of the salt of the compound, to the extent they can be made by one of ordinary skill in the art without undue experimentation.

[037] "Pharmaceutically acceptable salts" include, but are not limited to salts with inorganic acids, such as hydrochlorate, phosphate, diphosphate, hydrobromate, sulfate, sulfinate, nitrate, and like salts; as well as salts with an organic acid, such as malate, maleate, fumarate, tartrate, succinate, citrate, acetate, lactate,

methanesulfonate, p-toluenesulfonate, 2-hydroxyethylsulfonate, benzoate, salicylate, stearate, and alkanoate such as acetate, salts with HOOC-(CH ₂ ) _n -COOH where n is 0-4, and like salts. Similarly, pharmaceutically acceptable cations include, but are not limited to sodium, potassium, calcium, aluminum, lithium, and ammonium. [038] In addition, if a compound described herein is obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid salt.

Conversely, if the product is a free base, an addition salt, particularly a

pharmaceutically acceptable addition salt, may be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid, in

accordance with conventional procedures for preparing acid addition salts from base compounds. Those skilled in the art will recognize various synthetic methodologies that may be used without undue experimentation to prepare non-toxic

pharmaceutically acceptable addition salts.

[039] A "solvate, "such as a "hydrate," is formed by the interaction of a solvent and a compound. The term "compound" is intended to include solvates, including hydrates, of compounds, to the extent they can be made by one of ordinary skill in the art by routine experimentation. Similarly, "salts" includes solvates, such as hydrates, of salts, to the extent they can be made by one of ordinary skill in the art by routine experimentation. Suitable solvates are pharmaceutically acceptable solvates, such as hydrates, including monohydrates and hemi-hydrates, to the extent they can be made by one of ordinary skill in the art by routine experimentation.

[040] As used herein the terms "group", "radical" or "fragment" are synonymous and are intended to indicate functional groups or fragments of molecules attachable to a bond or other fragments of molecules.

[041] The term "active agent" is used to indicate a chemical substance which has biological activity. In some embodiments, an "active agent" is a chemical substance having pharmaceutical utility.

[042] "Treating," "treat," or "treatment" or "alleviation" refers to administering at least one compound and/or at least one pharmaceutically acceptable salt thereof described herein to a subject that has a disease or disorder, or has a symptom of a disease or disorder, or has a predisposition towarda disease or disorder, with the purpose to cure, heal, alleviate, relieve, alter, remedy, ameliorate, improve, or affect cancer, the symptoms ofthe disease or disorder, or the predisposition toward the disease or disorder. In some embodiments, the disease or disorder may be cancer. In some embodiments, the disease or disorder may be an inflammatory disease.

[043] The term "effective amount" refers to an amount of at least one compound and/or at least one pharmaceutically acceptable salt thereof described herein effective to "treat", as defined above, a disease or disorder in a subject responsive to the inhibition of Syk. The effective amount may cause any of the changes observable or measurable in a subject as described in the definition of "treating," "treat,"

"treatment" and "alleviation" above. For example, in the case of cancer, the effective amount can reduce the number of cancer or tumor cells; reduce the tumor size; inhibit or stop tumor cell infiltration into peripheral organs including, for example, the spread of tumor into soft tissue and bone; inhibit and stop tumor metastasis; inhibit and stop tumor growth; relieve to some extent one or more of the symptoms associated with the cancer, reduce morbidity and mortality; improve quality of life; or a combination of such effects. An effective amount may be an amount sufficient to decrease the symptoms of a disease responsive to inhibition of Syk kinase

[044] The term "effective amount" may also refer to an amount of at least one compound and/or at least one pharmaceutically acceptable salt described herein effective to inhibit the activity of Syk in a subject responsive to the inhibition of Syk..

[045]The term "inhibition" indicates a decrease in the baseline activity of a biological activity or process. "Inhibition of Syk" refers to a decrease in the activity of Syk kinase as a direct or indirect response to the presence of at least one compound and/or at least one pharmaceutically acceptable salt thereof described herein, relative to the activity of Syk kinase in the absence of the at least one compound and/or the at least one pharmaceutically acceptable salt thereof. The decrease in activity may be due to the direct interaction of the at least one compound and/or at least one pharmaceutically acceptable salt thereof described herein with the Syk kinase, or due to the interaction of the at least one compound and/or at least one pharmaceutically acceptable salt thereof described herein, with one or more other factors that in turn affect the at least one kinase activity. For example, the presence of at least one compound and/or at least one pharmaceutically acceptable salt thereof described herein, may decrease the at least one kinase activity by directly binding to the Syk kinase, by causing (directly or indirectly) another factor to decrease the at least one kinase activity, or by (directly or indirectly) decreasing the amount of the at least one kinase present in the cell or organism.

Cellular Assays

For the determination of IgE-induced Beta-hexosaminidase secretion, RBL-2H3 cells (SIBS) are seeded in 96 well plates at 4x10 ⁴ cells per well and incubated in MEM media with 15% FBS and Glutamine (2nM) for 4 hours and sensitized with 0.5 ug/ml of SPE-7 overnight. Cells are washed 3 times with Tyrode's buffer and incubated in the presence or absence of various concentrations of the testing compound for 20 min at 37 °C, 5% CO2. Cells are stimulated by adding 10 uL of DNP-BSA solution (150 ng/mL) to each well and incubating for 45 minutes at 37°C, 5% CO2. Then, 45 μΙ_ of the supernatant is taken and incubated with 100 μΙ_ of 1 mM 4-Nitrophenyl /V-acetyl-p-D-glucosaminide (Sigma, Cat. No. N9376), which is diluted in 0.05 M citrate buffer (pH 4.5), for 1 .5 hr at 37°C. The reactions are quenched by adding 185 μΙ_ of 0.05 M sodium carbonate buffer (pH 10.0). Plates are read at 405 nm on Multiskan (MK 3).
