FIELD OF THE INVENTIONThe present invention relates to a pharmaceutically useful compound having inhibitory activity on endthelial lipase (hereinafter, referred to as EL).
BACKGROUND ARTEndothelial lipase (EL) is a Triglyceride Lipase family on a par with Lipoprotein Lipase (LPL) and Hepatic Lipase (HL). Studies in the knockout mouse and transgenic mouse have indicated that EL is associated with HDLc metabolism by the strong phospholipase activity, and EL is accepted as a factor which regulates plasma HDLc levels (Non-Patent Document 1).
Plasma HDLc levels have been accepted as an inverse correlate of coronary artery disease (CAD) risk. HDLc is supposed to have an anti-atherosclerotic effect through acceleration of reverse cholesterol transport accompanied with anti-oxidizing and anti-inflammatory effects. Low HDLc levels are accepted as one of the risk factors of CAD.
Therefore, an EL inhibitor serves as a therapeutic agent for CAD through its effect of increasing HDLc levels. Actually, an increase of HDLc levels and a decrease of atherosclerotic lesion area have been reported in EL-deficient atherogenic mice (Non-Patent Document 2).
These facts suggest the possibility of a selective inhibitor of EL as a therapeutic agent for dyslipideamia and atherosclerosis.
Patent Document 1, 2 and 3 disclose various compounds having an inhibitory activity on hepatic lipase and/or endothelial lipase, but oxadiazole derivative such as the present compound has not been disclosed.
Patent Document 4 discloses a compound having inhibitory activity on triglyceride lipase, lipoprotein lipase, hepatic lipase, pancreatic lipase or endothelial lipase, but oxadiazole derivative such as the present compound has not been disclosed.
Patent Document 5 to 15 disclose various compounds having inhibitory activity on EL, but oxadiazole derivative such as the present compound has not been disclosed.
Patent Document 16 discloses an oxadiazole derivative having inhibitory activity on PDF (peptide deformylase). For example, the following compound is disclosed.
But patent document 16 does not describe any inhibitory activity on EL and the increasing activity of HDLc.

After a cell was retained at a membrane potential of −80 mV by whole cell patch clamp method using an automated patch clamp system (PatchXpress 7000A, Axon Instruments Inc.), IKr induced by depolarization pulse stimulation at +40 mV for 2 seconds and, further, repolarization pulse stimulation at −50 mV for 2 seconds was recorded. After the generated current was stabilized, extracellular solution (NaCl: 135 mmol/L, KCl: 5.4 mmol/L, NaH2PO4: 0.3 mmol/L, CaCl2.2H2O: 1.8 mmol/L, MgCl2.6H2O: 1 mmol/L, glucose: 10 mmol/L, HEPES (4-(2-hydroxyethyl)-1-piperazine ethanesulfonic acid): 10 mmol/L, pH=7.4) in which the test compound had been dissolved at an objective concentration was applied to the cell under the room temperature condition for 10 minutes. From the recording IKr, an absolute value of the tail peak current was measured based on the current value at the resting membrane potential using an analysis software (DataXpress ver.1, Molecular Devices Corporation). Further, the % inhibition relative to the tail peak current before application of the test substance was calculated, and compared with the vehicle-applied group (0.1% dimethyl sulfoxide solution) to assess influence of the test substance on IKr.
Powder Solubility TestAppropriate amounts of the test substances are put into appropriate containers. To the respective containers are added 200 μL of JP-1 fluid (sodium chloride 2.0 g, hydrochloric acid 7.0 mL and water to reach 1000 mL), 200 μL of JP-2 fluid (phosphate buffer (pH 6.8) 500 mL and water 500 mL), and 200 μL of 20 mmol/L TCA (sodium taurocholate)/JP-2 fluid (TCA 1.08 g and water to reach 100 mL). In the case that the test compound is dissolved after the addition of the test fluid, the bulk powder is added as appropriate. The containers are sealed, and shaken for 1 hour at 37° C. The mixtures are filtered, and 100 μL of methanol is added to each of the filtrate (100 μL) so that the filtrates are two-fold diluted. The dilution ratio may be changed if necessary. The dilutions are observed for bubbles and precipitates, and then the containers are sealed and shaken. Quantification is performed by HPLC with an absolute calibration method.
