The compounds of the present invention inhibit HMG-CoA reductase, and subsequently suppress the synthesis of cholesterol. And they are useful in the treatment of hypercholesterolemia, hyperlipoproteinemia, and atherosclerosis. The compounds have the formula ##STR1## wherein R.sup.1, R.sup.2, and R.sup.3 each is independently hydrogen, optionally substituted lower alkyl, or optionally substituted aryl; R.sup.4 is lower alkyl, aralkyl, aryl, or heteroaryl, each of which is optionally substituted; X is vinylene or ethylene; Y is ##STR2## where R.sup.5 is hydrogen, lower alkyl, aryl, aralkyl, or a cation capable of forming a non-toxic pharmaceutically acceptable salt.
本发明的化合物抑制HMG-CoA还原酶,随后抑制胆固醇的合成。它们在治疗高胆固醇血症、高脂蛋白血症和动脉粥样硬化方面具有用途。这些化合物的化学式为##STR1##其中R.sup.1、R.sup.2和R.sup.3分别独立地为氢、可选择取代的较低烷基或可选择取代的芳基;R.sup.4为较低烷基、芳基烷基、芳基或杂环芳基,每种都可选择取代;X为乙烯或乙烯基;Y为##STR2##其中R.sup.5为氢、较低烷基、芳基、芳基烷基或能形成无毒药用可接受盐的阳离子。
