Certain trans-6-[2-(N-heteroaryl-3,5-disubstituted) pyrazol-4-yl)ethyl]- or ethenyl]tetrahydro-4-hydroxy-2H-pyran-2-ones and the corresponding ring-opened acids, esters and N-oxides derived therefrom which are potent inhibitors of the enzyme 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG CoA reductase) and are thus useful hypolipidemic or hypocholesterolemic agents. Pharmaceutical compositions containing such compounds, and a method of inhibiting the biosynthesis of cholesterol employing such pharmaceutical compositions are also disclosed.
某些转-6-[2-(N-杂环芳基-3,5-二取代)吡唑-4-基)乙基]-或乙烯基]四氢-4-羟基-2H-吡喃-2-酮及其相应的环开放酸、酯和N-氧化物是3-羟基-3-甲基戊二酰辅酶A还原酶(HMG CoA还原酶)的有效抑制剂,因此可用作降脂或降胆固醇药物。还公开了含有这些化合物的制药组合物,以及使用这些制药组合物抑制胆固醇生物合成的方法。
