Abstract

Abnormal proliferation of vascular smooth muscle cells (VSMCs) plays an important role in the development and progression of proliferative cardiovascular diseases, including hypertension and atherosclerosis. To find antiproliferative agent (A)-8 had inhibitory effect on VSMCs proliferation. Therefore, we examined the antiproliferative effect of A-8, a newly synthesized obovatol derivative. To investigate the antiproliferative effect of A-8, we examined cell counting and [$^3H$]-thymidine incorporation assays. The pre-incubation of A-8 (1~4 ${\mu}M$) significantly inhibited proliferation and DNA synthesis of 5% fetal bovine serum (FBS)-stimulated rat aortic VSMCs in concentration-dependent manner. Whereas, A-8 did not show any cytotoxicity in rat aortic VSMCs in this experimental condition by WST-1 assay. In addition, A-8 significantly inhibited 5% FBS-induced cell cycle progression in rat aortic VSMCs. These results show that A-8 may be developed as a potential antiproliferative agent for treatment of angioplasty restenosis and atherosclerosis. Furthermore, A-8 should be examined for further clinical application either as a single agent or in combination with other angioplasty restenosis or atherosclerosis agents.
