The full experimental details for the total synthesis of (+)-compactin and 19 structural analogues are reported. We have evaluated three classes of analogues as inhibitors of 3-hydroxy-3-methylglutaryl-coenzyme A reductase: (1) functional and stereoisomeric analogues that possess the full carbon skeleton of compactin or dihydromevinolin, (2) functional analogues in which one carbon of the skeleton has
报告了完整合成(+)-compactin和19种结构类似物的完整实验细节。我们已经评估了三类类似物作为3-羟基-3-甲基戊二酰辅酶A还原酶的抑制剂:(1)具有全脂类固醇或二氢Mevinolin碳骨架的功能和立体异构类似物,(2)其中一个碳原子为骨架已被氧取代,和(3)类似物,其中所有3,5-二羟基戊酸部分均被省略。我们最有效的抑制剂属于第一类类似物。化合物42(5-酮-compactin)和69(5-ketodihydromevinolin)的活性分别与天然产品Compactin和二氢Mevinolin(I50 = 1-20 nM)相同。相应的烯酮37和68活性较低,其I 50值大20-30倍。颠倒C-3或C-5或紧密质素的六氢萘环的立体化学,可将I50提高到微摩尔范围内的值,与天然底物3-羟基-3-甲基戊二酰辅酶A的KM相当。 2类类似物在该浓度范围内也具有活性。针对紧密蛋白及其类似物开
