Lipid Lowering Oxopropanylindole Hydrazone Derivatives with Antioxidant and Anti-hyperglycemic Activity.

A series of substituted oxopropanylindole hydrazone derivatives was synthesized and evaluated for anti-oxidant and anti-dyslipidemic activity. Of the 12 tested, 3 compounds (6c, 7b and 7d) showed good anti-oxidant activity, compound 6c attenuated LDL oxidation by 32%. The compounds 6c and 7d also showed good anti-dyslipidemic activity by reducing serum levels of total cholesterol (TC), phospholipids (PL) and triglycerides (TG). These two compounds were further evaluated for antiadipogenic and anti-hyperglycemic activity, where 6c showed 44% reduction in lipid accumulation and 20.5% and 24.3% reduction in blood glucose at 5h and 24h respectively, as compared to standard drug metformin. Thus, compounds 6c and 7d with balanced anti-oxidant and anti-dyslipidimic activities may be excellent candidates for lead optimization and drug development for the treatment of metabolic disorders.
