A series of 5-substituted 3,5-dihydroxypentanoic acids and their derivatives have been prepared and tested for inhibition of HMG-CoA reductase in vitro. In general, unless a carboxylate anion can be formed and the hydroxy groups remain unsubstituted in an erythro relationship, inhibitory activity is greatly reduced. Furthermore, only one enantiomer of the ring-opened form of lactone 6a(+/-) possesses
已经制备了一系列5-取代的3,5-二羟基戊酸及其衍生物,并测试了其在体外对HMG-CoA还原酶的抑制作用。通常,除非可以形成羧酸根阴离子并且羟基以红邻关系保持未被取代,否则抑制活性会大大降低。此外,内酯6a(+/-)的开环形式的仅一种对映异构体具有外消旋体显示的活性。在5-甲醇部分和合适的亲脂性部分(例如2,4-二氯苯基)之间插入除乙基或(E)-乙烯基以外的桥联单元会减弱活性。
