FIELD OF THE INVENTION The present invention relates to compounds, compositions containing them, and their use for treating medical disorders where it is desirable to modulate the activity of hormone-sensitive lipase.

BACKGROUND OF THE INVENTION The overall energy homeostasis of a mammalian system requires a high degree of regulation to ensure the availability of the appropriate substrate at the appropriate time. Plasma glucose levels rise during the post-prandial state, to return to pre-prandial levels within 2-3 hours.

During these 2-3 hours, insulin promotes glucose uptake by skeletal muscle and adipose tis- sue and decreases the release of free fatty acids (FFA) from adipocytes, to ensure that the two substrates do not compete with each other. When plasma glucose levels fall, an eleva- tion in plasma FFA is necessary to switch from glucose to fat utilization by the various tis- sues.

In individuals with insulin resistance, FFA levels do not fall in response to insulin, as they do in normal individuals, preventing the normal utilization of glucose by skeletal muscle, adipose and liver. Furthermore, there is a negative correlation between insulin sensitivity and plasma FFA levels.

Hormone-sensitive lipase (HSL) is an enzyme, expressed primarily in adipocytes, that ca- talyses the conversion of triglycerides to glycerol and fatty acids. It is through the regulation of this enzyme that the levels of circulating FFA are modulated. Insulin leads to the inactiva- tion of HSL with a subsequent fall in plasma FFA levels during the post-prandial state, fol- lowed by the activation of the enzyme when the insulin concentration falls and catechola- mines rise during the post-absorptive period. The activation of HSL leads to an increase in plasma FFA, as they become the main source of energy during fasting.

The activation-inactivation of HSL is primarily mediated through the cAMP-protein kinase A and AMP-dependent kinase pathways. There are compounds like nicotinic acid and its de- rivatives, that decrease the activation of HSL via these pathways and cause a decrease in lipolysis that leads to a reduction in the FFA levels. These drugs have a beneficial effect in the utilization of glucose and in the normalization of the excess triglyceride synthesis seen in patients with elevated FFA. However, since these pathways are used by other processes in the body, these drugs have severe side effects.

We have found compounds that specifically inhibit the lipolytic activity of HSL and lead to a decrease in plasma FFA levels. These compounds can be used to treat disorders where a decreased level of plasma FFA is desired, such as insulin resistance, syndrome X, dyslipi- demia, abnormalities of lipoprotein metabolism.

One object of the present invention is to provide compounds and pharmaceutical composi- tions that inhibit the lipolytic activity of HSL. A further object is to provide compounds which have good pharmaceutical properties such as solubility, bioavailability etc.

One example is an acid addition salt of a compound having the utility of a free base. When a compound of the invention contains a free base such salts are prepared in a conventional manner by treating a solution or suspension of a free base of the compound with a chemical equivalent of a pharmaceutical acceptable acid, for example, inor- ganic and organic acids. Representative examples are mentioned above. Physiologically ac- ceptable salts of a compound with a hydroxy group include the anion of said compound in com- bination with a suitable cation such as sodium or ammonium ion.

For parenteral administration, solutions of the present compounds in sterile aqueous solution, aqueous propylene glycol or sesame or peanut oil may be employed. Such aqueous solutions should be suitable buffered if necessary and the liquid diluent first rendered isotonic with suffi- cient saline or glucose. The aqueous solutions are particularly suitable for intravenous, intra- muscular, subcutaneous and intraperitoneal administration. The sterile aqueous media em- ployed are all readily available by standard techniques known to those skilled in the art.

Suitable pharmaceutical carriers include inert solid diluents or fillers, sterile aqueous solution and various organic solvents. Examples of suitable carriers are water, salt solutions, alcohols, polyethylene glycols, polyhydroxyethoxylated castor oil, peanut oil, olive oil, gelatine, lactose, terra alba, sucrose, cyclodextrin, amylose, magnesium stearate, talc, gelatin, agar, pectin, acacia, stearic acid or lower alkyl ethers of cellulose, silicic acid, fatty acids, fatty acid amines, fatty acid monoglycerides and diglycerides, pentaerythritol fatty acid esters, polyoxyethylene, hydroxymethylcellulose and polyvinylpyrrolidone. Similarly, the carrier or diluent may include any sustained release material known in the art, such as glyceryl monostearate or glyceryl distearate, alone or mixed with a wax. The formulations may also include wetting agents, emulsifying and suspending agents, preserving agents, sweetening agents or flavouring agents.

The pharmaceutical compositions formed by combining the compounds of the invention and the pharmaceutically acceptable carriers are then readily administered in a variety of dosage forms suitable for the disclosed routes of administration. The formulations may conveniently be pre- sented in unit dosage form by methods known in the art of pharmacy.

Methods.

3180.1 : Assay for determination of inhibitor IC50 values.

A lipid emulsion with 3H-Triolein and phospholipid is used as substrate with a standard cencentration of highly purified HSL. BSA is added as product receptor. The substrate is prepared as follows : 30 pi PC: PI (20 mg/ml solution of PC: PI 3: 1 prepared in chloroform) + 128 pi cold TO + 15, ul 3H-TO are mixed and then evaporated under a gentle stream of N2 followed by 20-30 min- utes in a Speedvac to ensure the absence of residual solvent.

Compound and HSL are incubated for 30 min at 25 °C before addition of substrate. Reaction is stopped after 30 min at 25 °C by adding a mixture of methanol, chloroform and heptane at high pH. Formed product is separated from substrate by phase separation.

Standard concentrations of compound are 100, uM, 20, uM, 4, uM, 0. 8, uM, 0. 16, uM and 0. 032, uM (sample concentrations).

Results are given as percent activity relative to an un-inhibited sample (no compound).

3190.1 : Assay for determination of percent inhibition of hormone sensitive lipase by com- pound at 10, uM sample concentration.

A lipid emulsion with fluorochrome-labeled triacylglyceride and phospholipid is used as sub- strate with a standard concentration of highly purified HSL (12pg/mL initial concentration cor- responding to 600ng/mL final concentration). BSA is added as product receptor. The transfer of the fluorochrome from the lipid phase to the water (BSA) phase changes the fluorescent properties of the fluorochrome. The changes can be monitored on a fluorimeter with an exci- tation wavelength of 450nm and an emission wavelength of 545nm.

Compound and HSL (20pL compound, 1 OpL enzyme and 70pL PED-BSA buffer) is pre- incubated for 30min at 25°C before addition of substrate (100uL). Amount of formed product is measured after 120min incubation at 37°C.

Results are given as percent activity relative to a non-inhibited sample (no compound).

2848.2 : This high-volume screening assay uses para-nitrophenyl butyrate (p-NPB) as sub- strate for HSL. HSL cleaves p-NPB and the reaction is monitored as an increase in the con- centration of para-nitrophenol (p-NP). p-NP can be monitored as an increase in UV- absorbance at 405 nm. The reaction is carried out at room-temp. for 20 min. The action is not stopped, but instead UV-abs is measured at a fixed time (20 min. ) Due to autohydrolysis of the substrate the reaction is read at t = 0 min. too and t = 20 min. and the increase in Abs is calculated as the difference between the two readings. When a compound that inhibits HSL is present, it results in a relative decrease in UV-absorbance.

% Eff (%) nhibition) = (S-SOEff)/ (SmaxEff-SOEff) x 100 Where S = signal in UV-abs. , SOEff = assaybuffer alone, SmaxEff = Assaybuffer with the li- pase inhibitor.

2898.2 : This method is an enzyme assay based upon SPA (scintillation proximity assay) par- ticles. The substrate, 1, 3-(di-[3H]-stearin), 2-(PEG-Biotin)-glycerol, is marked with 3H in both fatty acid moieties in the tri-glyceride. The third moiety of the tri-glyceride is a PEG linked Biotin. The substrate binds through Biotin to streptavidin in the SPA particles and the prox- imity between the radioactive tritium in the stearic acid moiety and the SPA particle results in emission of light from the SPA particles. The assay is an on-bead assay where HSL de- grades the substrate, where after 3H-stearin acid is released from the bead. The amount of light emitted is proportional to the amount of substrate bound to the receptor. When a com- pound that inhibits the activity of HSL is present it results in a decrease in degradation of the substrate and thus an increase in the amount of light emitted and a concomitant increase in % Eff.

% Eff (% Inhibition) = (S-S0Eff)/ (SmaxEff-SOEff) x 100 Where S = signal in dpm., SOEff = no inhibitor added, SmaxEff = with maximum concentra- tion of inhibitor.
