an isopropyl or cyclopropyl group at the 2 position of the indolizine are among the most potent calcium antagonists known outside the 1,4-dihydropyridine series. The IC50 values for the inhibition of [3H]nitrendipine binding vary between 0.19 and 4.5 nM whereas the IC50 value for nifedipine is 2.5 nM. One of the compounds in this group (9ab) has now been selected for clinical development.
描述了一系列1-磺酰林多嗪的合成和初步生物学评估。这些化合物已被证明是一类新型的有效的慢通道钙拮抗剂。发现所有化合物的活性至少与参考钙拮抗剂维拉帕米和顺-(+)-地尔硫卓相同。结构-活性关系研究表明,所有在胺部分具有芳烷基基团和在吲哚嗪的2位上具有异丙基或环丙基基团的化合物都是1,4-二氢吡啶系列以外已知最有效的钙拮抗剂。抑制[3H]硝苯地平结合的IC50值在0.19至4.5 nM之间变化,而硝苯地平的IC50值为2.5 nM。现在已选择该组中的一种化合物(9ab)用于临床开发。
