Structure-based drug design of novel isoquinoline-5-sulfonamide inhibitors of PKB as potential antitumour agents was investigated. Constrained pyrrolidine analogues that mimicked the bound conformation of linear prototypes were identified and investigated by co-crystal structure determinations with the related protein PKA. Detailed variation in the binding modes between inhibitors with similar overall
研究了新型PKB异喹啉5磺酰胺抑制剂作为潜在抗肿瘤药的基于结构的药物设计。鉴定并模拟了线性原型的结合构象的约束吡咯烷类似物,并通过与相关蛋白PKA的共晶体结构测定进行了研究。观察到具有相似总体构象的抑制剂之间结合模式的详细变化。该系列中的强效PKB抑制剂在细胞测定中抑制GSK3beta磷酸化,与细胞中PKB激酶活性的抑制一致。
