and 8 of the central quinoline nucleus moderately affected the potency, whereas the alkyl side chain on the 2-position had a more pronounced influence on activity. Among the derivatives, NK-104 (pitavastatin calcium), which has a cyclopropyl group as the alkyl side chain, showed the greatest potency. We found that further modulation and improvement in potency at inhibiting HMG-CoA reductase was obtained
由喹啉羧酸酯经同源,醛基与乙酰乙酸乙酯双阴离子缩醛反应和3-羟基酮还原合成了一系列基于喹啉的3,5-二羟基庚酸衍生物,以评价其体外抑制HMG-CoA还原酶的能力。与先前的文献一致,在外环上存在严格的结构要求,并且4-氟苯基在该系统中最活跃。对于中心环,在中心喹啉核的6、7和8位上的取代会适度影响效价,而在2位上的烷基侧链对活性有更明显的影响。在衍生物中,具有环丙基作为烷基侧链的NK-104(匹伐他汀钙)显示出最大的效力。
