Novel 6-[2-[2-(substituted amino)-3-quinolinyl]-ethenyl and ethyl]tetrahydro-4-hydroxypyran-2-ones and/or oxides and the corresponding dihydroxy ring opened acids and esters are described, as well as methods for the preparation and pharmaceutical compositions of same, which are useful as inhibitors of the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase) and are thus useful hypolipidemic and hypocholesterolemic agents.
本发明涉及6-[2-[2-(取代
氨基)-3-
喹啉基]-
乙烯基和乙基]四氢-
4-羟基吡喃-2-酮和/或氧化物以及相应的二羟基环开放酸和酯,以及其制备方法和制备的药物组合物。这些化合物可作为3-羟基-3-甲基戊二酰
辅酶A还原酶(
HMG-CoA还原酶)的
抑制剂,因此可作为降血脂和降
胆固醇剂使用。
