8-trisubstituted-4-chloro-quinoline-3-carboxylates by several reactions and evaluated for their ability to inhibit the rat HMG CoA reductase in vitro. It was found that substitution with a variety of thiophenyl groups at position 4 in quinoline resulted in retention or enhancement of the inhibition and the preferable groups were 4-isopropyl-thiophenyl and 3-methoxy-thiophenyl.

由6,7,8-三取代-4-氯喹啉-3-羧酸乙酯经数个反应合成了一系列新颖的基于4-硫代苯基喹啉的甲羟戊酸内酯衍生物,并评估了它们在体外抑制大鼠HMG CoA还原酶的能力。 。发现在喹啉的4位上被各种硫代苯基取代会导致抑制作用的保持或增强,优选的基团是4-异丙基-硫代苯基和3-甲氧基-硫代苯基。(4R,6S)-6-[(E)-2-(6,7,8-三氟-4-异丙基硫代苯基-喹啉-3-基)-乙烯基]-3,4,5,6-四氢-4-羟基-2H-吡喃-2-酮(A16)和(4R,6S)-6-[(E)-2-(6-氟-4,7-二-(3-甲氧基-硫代苯基)-喹啉-3 -基)-乙烯基] -3,4,5,
