Synthesis and biological evaluation of 1,3,4-oxadiazole-linked bisindole derivatives as anticancer agents
摘要:
A series of ten 1,3,4-oxadiazole-linked bisindole derivatives have been synthesized. All compounds were evaluated for anticancer activity against four human cancer cell lines (MCF-7, KB, Colo-205, and A-549). Most of these new compounds exhibited significant anticancer activity as compared to etoposide. Compounds' GI(50) values range from < 0.1 to 3.9 mu M, while the positive control etoposide has a GI(50) in the range of 0.13-3.08 mu M in the cell lines employed. Among them, four compounds showed a higher activity than etoposide.
Indole-Based Fibrates as Potential Hypolipidemic and Antiobesity Agents
摘要:
Hypolipidemic and antiobesity effects of the newly synthesized indole-based fibrates were evaluated in Triton WR-1339 and high fat diet (HFD)-induced hyperlipidemic rats. Preliminary screening of all the synthesized compounds was done by using an acute model (Triton model), in which compounds 3f and 3l showed significant antidyslipidemic activity. Furthermore, these compounds 3f and 3l were found to induce significant weight loss in the visceral fat mass of HFD-fed hyperlipidemic rats without affecting the normal feeding behavior. Histological examination of the liver of rats supplemented with 3f and 3l revealed a significant decrease in steatosis when compared to the effect of the standard drug fenofibrate. Additional effects such as an increase in lecithin cholesterol acyl-transferase (LCAT) enzyme level and increased receptor mediated catabolism of I-131-low density lipoproteins (LDL) confirm and reinforce the efficacy of both of these compounds as a new class of dual-acting hypolipidemic and antiobesity agents.
