The present invention relates to compounds of the general formula (I), their tautomeric forms, their stereoisomers, their pharmaceutically acceptable salts, pharmaceutical compositions containing them, methods for their preparation, use of these compounds in medicine and the intermediates involved in their preparation.
The present invention is directed towards compounds which can be used to treat diseases such as hyperlipidemia and also have a beneficial effect on cholesterol.
The compounds of the general formula (I) lower or modulate triglyceride levels and/or cholesterol levels and/or low-density lipoproteins (LDL) and raises the high-density lipoproteins (HDL) plasma levels, lower blood glucose and hence are useful in combating different medical conditions, where such lowering of LDL (and/or raising of HDL) is beneficial. Thus, it could be used in the treatment and/or prophylaxis of obesity, hyperlipidemia, hypercholesteremia, hypertension, atherosclerotic disease events, vascular restenosis, diabetes and many other related conditions.
The compounds of general formula (I) are useful to prevent or reduce the risk of developing atherosclerosis, which leads to diseases and conditions such as artereosclerotic cardiovascular diseases, stroke, coronary heart diseases, cerebrovascular diseases, peripheral vessel diseases and related disorders.
These compounds of general formula (I) are useful for the treatment and/or prophylaxis of metabolic disorders loosely defined as Syndrome X. The characteristic features of Syndrome X include initial insulin resistance followed by hyperinsulinemia, dyslipidemia and impaired glucose tolerance. The glucose intolerance can lead to non-insulin dependent diabetes mellitus (NIDDM, Type 2 diabetes), which is characterized by hyperglycemia, which if not controlled may lead to diabetic complications or metabolic disorders caused by insulin resistance. Diabetes is no longer considered to be associated only with glucose metabolism, but it affects anatomical and physiological parameters, the intensity of which vary depending upon stages/duration and severity of the diabetic state. The compounds of this invention are also useful in prevention, halting or slowing progression or reducing the risk of the above mentioned disorders along with the resulting secondary diseases such as cardiovascular diseases, like arteriosclerosis, atherosclerosis; diabetic retinopathy, diabetic neuropathy and renal disease including diabetic nephropathy, glomerulonephritis, glomerular sclerosis, nephrotic syndrome, hypertensive nephrosclerosis and end stage renal diseases, like microalbuminuria and albuminuria, which may be result of hyperglycemia or hyperinsulinemia.
The compounds of the present invention can be useful as aldose reductase inhibitors; for improving cognitive functions in dementia, and in the treatment and/or prophylaxis of disorders such as psoriasis, polycystic ovarian syndrome (PCOS), cancer, osteoporosis, leptin resistance, inflammation and inflammatory bowel diseases, wound healing, xanthoma, pancreatitis, myotonic dystrophy, endothelial cell dysfunction and hyperlipidemia.
Higher LDL cholesterol levels in the plasma increase cardiovascular risk and reduction in the levels of LDL would decrease CVD risk by a comparable percentage (PNAS, 2009, 106, 9546-9547). Clearance of LDL cholesterol from plasma is through the action of LDL receptors in the liver and LDL receptors are cell surface glycoproteins that bind to apolipoprotein B100 (apoB100) on LDL particles with high affinity and mediate their endocytic uptake (Journal of Biological Chemistry, 2009, 284, 10561-10570). Defect in hepatic cholesterol clearance and elevated levels of plasma LDL cholesterol that result from the mutations cause familial hypercholesterolemia. Such mutations are identified in the human LDL receptor and later in apolipoprotein-B (Nature Structural and Molecular Biology, 2007, 14, 413-419). Recently, mutations within certain subtypes of the pro-protein convertasesubtilisin/gene such as the subtype nine (hereinafter “the gene”) were found to represent a third class of mutations associated with autosomal dominant hypercholesterolemia (ADH). The discovery, etiology and functions of this subtype gene is discussed in details in Nature Genetics, 2003, 34, 154-156, Trends in Biochemical Sciences, 2008, 33, 426-434 etc. Several missense mutations (S127R, D129G, F216L, D374H, D374Y) are associated with hypercholesterolemia and premature atherosclerosis (J Lipid Res. 2008, 49, 1333-1343). Loss-of-function mutations (R46L, L253F, A433T) lead to elevated receptor abundance, enhancing clearance of LDL cholesterol from the circulation and reducing cardiovascular risk (Nature Structural and Molecular Biology, 2007, 14, 413-419).
Detailed molecular mechanisms explaining the association of LDLR and the particular subtype gene and LDLR degradation is not very clear (Drug News Perspectives, 2008, 21, 323-330). Because of inhibition of LDLR recycling, number of LDL receptors on the cell surface are decreased and this increases plasma LDL levels (PNAS, 2009, 106, 9546-9547).
Various approaches for inhibiting this particular subtype gene are reported, including gene silencing by siRNA or antisense oligonucleotides, mAb disrupting protein-protein interactions or by peptides; all the above-mentioned strategies have shown lowering of LDL cholesterol which may be effective therapy for treating hypercholesterolemia (Biochemical Journal, 2009, 419, 577-584; PNAS, 2008, 105, 11915-11920; Journal of Lipid Research, 2007, 48, 763-767; PNAS, 2009, 106, 9820-9825). However, very little success has been reported in trying to inhibit this subtype gene by using small molecules. Such small molecule inhibitors have their obvious clinical and therapeutic benefits over the other known approaches as discussed above. We herein disclose novel small molecules which have shown to inhibit this particular gene in in-vitro studies and therefore provide an alternate beneficial approach for treating patients in need of such therapy.
We have disclosed earlier compounds which inhibits this particular gene in patent applications no. WO2015107541, WO2014192023, WO2012090220, WO2014002105. Inhibitors of this gene have been disclosed by few companies in application no WO2014150395, WO2014150326, WO 2014151936, WO2016021706, WO2016055901, WO2017222953, WO2017034990, WO2017034997, WO2017034994, WO2018165718, WO2018053517, WO2018057409, WO2020110009, WO2020150473, WO2020150474, WO 2020028723.

BODIPY-LDL Uptake Assay in HepG2 Cells.
An established assay for PCSK9 inhibition features uptake of fluorescently labeled LDL nanoparticles (BODIPY-LDL) by hepatocytes and uptake of the BODIPY-containing particles is maximized in the absence of PCSK9.
In the LDL uptake assay, HepG2 cells were seeded at a density of 6×104 cells/well in a 96-well plate. After 24 h, the test compounds at various concentrations were pre-incubated with 5 μg/ml PCSK9 in 0.2% DMSO for 60 min prior to the addition on to the cells. After 16 h the medium was removed and 1 μg/ml BODIPY-LDL (Invitrogen) in serum free media was added and incubated for 5 h. Then the cells were washed twice with 0.25% BSA in PBS. Then the fluorescence of the cells in PBS was measured using TECAN multimode reader (Excitation: 485 nm and Emission: 520 nm). The readings were taken in triplicate and the final values were normalized with the protein concentration from respective wells. The wells without test compound containing external PCSK9 is considered as zero uptake and the one without PCSK9 was considered as 100% uptake. The percentage increase in LDL uptake for the test compounds were calculated using these values. The results are presented in the table 1 below.
LDL-C Lowering Activity—in High Fat Diet C57 Mice
The in-vivo LDL-c lowering for test compound was tested in C57 mice which were kept on high fat diet for 4 weeks and the blood was collected by retro-orbital sinus puncture method under light ether anesthesia on day 0 (pretreatment). Animal are grouped based on LDL-c levels, after that 7 days treatment with vehicle or test compound orally at a dose of 30 mpk dose once a day was given. On completion of treatment on day 7 of the treatment the blood was collected for LDL-c and TC levels measurement. The percent change in LDL-c and TC in test compound group Vs Vehicle group was calculated and presented in the table 2 below
