摘要：

Cilostazol, a cyclic AMP phosphodiesterase inhibitor, has been used as an antiplatelet agent. In the present study, we investigated the in vitro effect of cilostazol on DNA synthesis in rat aortic arterial smooth muscle cells (SMCs) in culture stimulated with fetal calf serum (FCS), platelet-derived growth factor (PDGF), insulin, or insulin-like growth factor-I (IGF-I). Micromolar concentrations of cilostazol inhibited [H-3]thymidine incorporation into DNA and cell growth as determined by cell number and protein concentration. Treatment with cilostazol increased the intracellular concentration of cyclic AMP, suggesting that the inhibition of SMC proliferation by cilostazol may be mediated through increased levels of cyclic AMP. The results suggested that cilostazol, by interfering with the proliferation of arterial SMCs, may have potential to prevent initiation and progression of atherosclerosis.
