with these compounds. In functional studies both PK 11195 (1-(2-chlorophenyl)-N-methyl-N-(1-methylpropyl)-3-isoquinolinecarboxa mide) and Ro 5-4864 (4'-chlorodiazepam) did not display selectivity between cardiac and vascular tissue. Therefore, several 7-(acyloxy)-6-arylpyrrolo[2,1-d][1,5]benzothiazepines, potent and selective peripheral-type benzodiazepine receptor ligands recently developed by us (3
描述了一系列新型吡咯并[2,1-d] [1,5]-苯并硫氮杂derivatives衍生物(54-68)的合成和心血管表征。最近发现选择性外围型苯并二氮杂receptor受体(PBR)配体(例如PK 11195和Ro 5-4864)具有低但显着的L型钙通道抑制活性,并且该特性与通过观察到的心血管作用有关。这些化合物。在功能研究中,PK 11195(1-(2-氯苯基)-N-甲基-N-(1-甲基丙基)-3-异喹啉羧甲)和Ro 5-4864(4'-氯二氮杂)均未显示对心脏和心脏的选择性。血管组织。因此,我们最近开发出了几种7-(酰氧基)-6-芳基吡咯并[2,1-d] [1,5]苯并噻氮平,有效的和选择性的外围型苯并二氮杂receptor受体配体(3,7-20),进行钙通道受体结合测定。这些化合物中的某些显示出从L型钙通道置换[3H]硝苯地平的结合作用的出乎意料的效力,远高于PK 11195和Ro
