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 tissue 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 elevation in plasma FFA is necessary to switch from glucose to fat utilization by the various tissues.
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 catalyses 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 inactivation of HSL with a subsequent fall in plasma FFA levels during the post-prandial state, followed by the activation of the enzyme when the insulin concentration falls and catecholamines 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 derivatives, 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, dyslipidemia, abnormalities of lipoprotein metabolism.
One object of the present invention is to provide compounds and pharmaceutical compositions that inhibit the lipolytic activity of HSL. A further object is to provide compounds which have good pharmaceutical properties such as solubility, bioavailability etc.

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 concentration of highly purified HSL. BSA is added as product receptor. The substrate is prepared as follows:
30 μl PC:PI (20 mg/ml solution of PC:PI 3:1 prepared in chloroform)+128 μl cold TO+15 μl 3H-TO are mixed and then evaporated under a gentle stream of N2 followed by 20–30 minutes 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 μM, 20 μM, 4 μM, 0.8 μM, 0.166 μM and 0.032 μM (sample concentrations).
Results are given as IC50 values after 4PL fit of obtained activity data.

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 μl PC:PI (20 mg/ml solution of PC:PI 3:1 prepared in chloroform)+128 μl cold TO+15 μl 3H-TO are mixed and then evaporated under a gentle stream of N2 followed by 20–30 minutes 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.
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 compound at 10 μM sample concentration.
A lipid emulsion with fluorochrome-labeled triacylglyceride and phospholipid is used as substrate with a standard concentration of highly purified HSL (12 μg/mL initial concentration corresponding to 600 ng/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 excitation wavelength of 450 nm and an emission wavelength of 545 nm.
Compound and HSL (20 μL compound, 10 μL enzyme and 70 μL PED-BSA buffer) is pre-incubated for 30 min at 25° C. before addition of substrate (100 μL). Amount of formed product is measured after 120 min incubation at 37° C.
Results are given as percent activity relative to a non-inhibited sample (no compound).
3190.2: Assay for determination of IC50 value for the inhibition of hormone sensitive lipase by compound. Standard concentrations of compound are 100 μM and 5-fold dilutions (initial concentration corresponding to 10 μM final concentration and 5-fold).
A lipid emulsion with fluorochrome-labeled triacylglyceride and phospholipid is used as substrate with a standard concentration of highly purified HSL (12 μg/mL initial concentration corresponding to 600 ng/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 excitation wavelength of 450 nm and an emission wavelength of 545 nm.
Compound and HSL (20 μL compound, 10 μL enzyme and 70 μL PED-BSA buffer) is pre-incubated for 30 min at 25° C. before addition of substrate (100 μL). Amount of formed product is measured after 120 min incubation at 37° C.
Results are given as IC50 values after 4PL fit of obtained activity data.
2848.2: This high-volume screening assay uses para-nitrophenyl butyrate (p-NPB) as substrate for HSL. HSL cleaves p-NPB and the reaction is monitored as an increase in the concentration 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(% Inhibition)=(S−S0Eff)/(SmaxEff−S0Eff)×100

Where S=signal in UV-abs., S0Eff=assaybuffer alone, SmaxEff=Assaybuffer with the lipase inhibitor.

2898.2: This method is an enzyme assay based upon SPA (scintillation proximity assay) particles. 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 proximity 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 degrades 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 compound 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−S0Eff)×100

Where S=signal in dpm., SOEff=no inhibitor added, SmaxEff=with maximum concentration of inhibitor.
