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 μM) 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.
