lactone analogue of the artificial tumor promoter benzolactam-V8 (1). To investigate the effect of hydrophobic substituents at positions 7 and 15 of 4 on binding selectivity for protein kinase C (PKC) isozymes, 7- and 15-decylbenzolactone-V8 (7, 8) were synthesized and their binding affinities for synthetic PKC isozyme C1 peptides were examined. Compound 8 showed moderate selectivity for novel PKC isozymes
苯甲内酯-V8(4)是人工肿瘤启动子苯并内酰胺-V8(1)的
内酯类似物。为了研究4位7和15上的疏
水取代基对蛋白激酶C(PKC)同工酶的结合选择性的影响,合成了7-和15-
癸基苯甲内酯-V8(7,8)以及它们对合成PKC同工酶C1的结合亲和力检查肽。化合物8对类似于9-
癸基苯甲内酯-V8(5)的新型PKC同工酶显示出中等选择性,而7则选择性较低。与8-
癸基苯并内酯-V8不同,化合物7和8在新型PKC同工酶中没有显示出明显的选择性(6)。这些结果表明,在4的8位上引入疏
水取代基最有效地开发了PKCε-和PKCeta-选择性粘合剂。
