Design, synthesis and in vivo screening of some novel quinazoline analogs as anti-hyperlipidemic and hypoglycemic agents.

A novel series of substituted quinazoline derivatives were designed, synthesized and evaluated for their hypolipidemic activity in cholesterol induced hyperlipidemic rats. In vivo screening concluded that compounds A-4, C-5 and C-6 have shown potent antihyperlipidemic activity by decreasing the plasma level of triglycerides (TG), very low density lipoprotein (VLDL), low density lipoprotein (LDL), followed by increase in level of high density lipoprotein (HDL).

Synthesis of novel amides based on acridone scaffold with interesting antineoplastic activity.

In search of novel cytotoxic agents based on acridone scaffold, twenty five derivatives of acridone-2- carboxamide were synthesized and evaluated against a panel of eleven cancer cell lines by using MTT assay. Amides, A5 and A8 (IC50 = 0.3 µM) exhibited good cytotoxicity against MCF7.

Unequivocal role of pyrazine ring in medicinally important compounds: a review.

Pyrazine is one of the important class of heterocyclic compounds that can be obtained naturally or synthesized chemically. Pyrazine ring has got importance in exhibiting various biological activities in association with other scaffolds like pyrrole, pyrazole, imidazole, triazole, tetrazole, thiophene, oxazole, pyridine, piperidine and piperazine. Presence of pyrazine ring as a basic scaffold in various clinically used drugs exhibits its importance in drug design.
