  Inhibitors of cholesterol biosynthesis. 6. trans-6-[2-(2-N-heteroaryl-3,5-disubstituted-pyrazol-4-yl)ethyl/ethenyl]tetrahydro-4-hydroxy-2H-pyran-2-ones

  摘要：

  A series of N-heteroaryl-substituted mevalonolactones were prepared and evaluated for their ability to inhibit the enzyme HMG-CoA reductase both in vitro and in vivo, and to lower plasma cholesterol in a hypercholesterolemic dog model. The goal of the strategy employed was to design an inhibitor which possessed the pharmacological properties of lovastatin (1), and the physicochemical properties (increased hydrophilicity) of pravastatin (2). Two compounds 20a and 20b, were more potent than lovastatin at inhibiting cholesterol biosynthesis both in vitro and in vivo. In terms of plasma cholesterol lowering, 20a was much more efficacious than lovastatin. In addition to possessing increased biological activity, these compounds are significantly less lipophilic than lovastatin, in fact, 20b has a CLOGP value comparable to pravastatin.

  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 hydrolipidemic or hypocholesterolemic agents. Pharmaceutical compositions containing such compounds, and a method of inhibiting the biosynthesis of cholesterol employing such pharmaceutical compositions are also disclosed.

  本发明涉及某些特定的trans-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-酮及其相应的开环酸、酯和N-氧化物。它们是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剂。本发明还涉及含有这种化合物的药物组合物，以及使用这种药物组合物抑制胆固醇生物合成的方法。
