inactive on these parameters, three of them did show interesting cardiovascular action. In particular they produced a more pronounced decrease in CPP than verapamil, with a less marked negative inotropic effect. Structure-activity relationships and the mechanism of action of the compounds are discussed.
合成了许多维拉帕米的芴基和二苯基甲烷类似物,它们被选择为具有相同的取代基,这些取代基以不同的方式排列在四级碳周围,以评估该分子在该点上立体异构的重要性。使用Langendorff技术测试这些化合物,并记录冠状动脉灌注压(CPP),左心室压(LVP)和心率(HR)。尽管大多数化合物对这些参数几乎没有活性,但其中三个确实表现出有趣的心血管作用。特别是,它们比维拉帕米产生的CPP降低更为明显,负性肌力作用较小。讨论了化合物的构效关系和作用机理。
