previously reported molecular modeling analyses of the interactions between the inhibitor microcystin and the serine-threonine protein phosphatases 1 and 2A, we have designed analogues of microcystin LA with structural modifications intended to impart PP1 selectivity. The synthesis of several first generation analogues followed by inhibition assays revealed that all three are PP1-selective, as predicted
基于先前报道的抑制剂微囊藻毒素与丝氨酸-苏氨酸蛋白磷酸酶1和2A相互作用的分子模型分析结果,我们设计了微囊藻毒素LA类似物,其结构修饰旨在赋予PP1选择性。几个第一代类似物的合成以及随后的抑制分析表明,正如预测的那样,所有这三种都是PP1选择性的。尽管观察到的选择性中等,但设计的类似物之一对PP1的选择性比任何已知的小分子抑制剂都高。
