The synthesis of certain new 8-(arythio)- and 8-(alkylthio)-cAMP derivatives and N6-alkyl- and N6-dialkyl-8-(arylthio) and -8-(alkylthio) derivatives of cAMP is reported. On the basis of activation of protein kinase, several N6-alkyl-8-(benzylthio)-cAMP derivatives were selected for evaluation as inotropic agents using cat papillary muscle in vitro. Activity in these studies resulted in the selection
报道了某些新的8-(芳硫基)-和8-(烷硫基)-cAMP衍生物以及cAMP的N6-烷基-和N6-二烷基-8-(芳硫基)和-8-(烷硫基)衍生物的合成。基于蛋白激酶的激活,选择了几种N6-烷基-8-(苄硫基)-cAMP衍生物作为体外使用猫乳头肌的肌力药物进行评估。这些研究中的活动导致选择了几种类似物用于在麻醉犬中进行体内研究。在体内研究的基础上选择的最好的正性肌力药是N6-丁基-8-(苄硫基)-cAMP(26),其血液流速增加了85%,而心率却没有增加。据报道,通过N1-烷基化从cAMP大规模合成26,然后通过苄基硫醇进行Dimroth重排,还原,溴化和亲核取代。N6-烷基-8-取代的-cAMP衍生物代表了一类新的强力变力剂。26的直接作用机制表明该环状核苷酸可能通过快速静脉内输注治疗临床心肌梗塞。
