To study the effects of pinacidil (Pin), nicorandil (Nic), RP 49356 (RP), and lemakalim (Lem) on phenylephrine (PE)-induced proliferation of cultured rabbit aortic smooth muscle cells (ASMC).
The [3H]thymidine incorporation into DNA and number of ASMC were measured.
[3H]Thymidine uptake induced by PE was markedly inhibited by Pin, Nic, RP, and Lem (0.1-10 mumol.L-1). Only RP inhibited [3H]thymidine uptake without PE-pretreatment. Cell growth induced by PE was completely inhibited by Pin.
Pin, Nic, RP, and Lem showed potent antiproliferation of ASMC.
研究吡那地尔(Pin)、尼可地尔(Nic)、RP 49356(RP)和雷马卡林(Lem)对去氧肾上腺素(PE)诱导的培养兔主动脉平滑肌细胞(ASMC)增殖的影响。
测定[³H]胸腺嘧啶核苷掺入DNA的量及ASMC的数量。
Pin、Nic、RP和Lem(0.1 - 10 μmol·L⁻¹)显著抑制PE诱导的[³H]胸腺嘧啶核苷摄取。仅RP在无PE预处理时抑制[³H]胸腺嘧啶核苷摄取。Pin完全抑制PE诱导的细胞生长。
Pin、Nic、RP和Lem对ASMC显示出强大的抗增殖作用。
