vascular smooth muscle cells showed a strong stimulating effect on elastin synthesis, especially compound B16, which was more active at 20 μM than diazoxide, a reference ATP-sensitive potassium channel activator. Taken together, our results show that the N-methylation of the sulfonylurea moieties of ring-opened cromakalim analogues led to new compounds blocking calcium-gated channels, which had a major
合成了两个新的含cromakalim的含磺酰脲部分的开环类似物系列(A系列:带有N-未甲基化的磺酰脲,B系列:带有N-甲基化的磺酰脲),并作为血管和呼吸道平滑肌(大鼠主动脉和气管,分别)。离体生物学评估表明,活性最高的化合物(系列B)对内皮完整的主动脉环和气管表现出显着的血管舒张活性。大多数B系列化合物的血管舒张活性(EC 50 <22μM)比参考化合物二氮嗪(EC 50)高 = 24μM)。有趣的是,与参考化合物克罗马卡林(EC 50 = 124μM),特别是化合物B4,B7和B16(EC 50 <10μM)相比,几种B系列测试化合物在气管上也表现出更强的松弛作用。与此相反,系列甲衍生物是在主动脉环差的活性(EC 50 > 57μM所有,并且EC 50 > 200μM为其中大部分),但它们中的一些显示出了一个有趣的放宽对气管(即作用A15和A33,EC 50 = 30μM)。
