  摘要：

  A novel series of trans-6-(2-pyrrol-1-ylethyl)-4-hydroxypyran-2-ones and their dihydroxy acid derivatives were prepared and evaluated for their ability to inhibit the enzyme HMG-CoA reductase in vitro. A systematic study of substitution at the 2- and 5-positions of the pyrrole ring revealed that optimum potency was realized with the 2-(4-fluorophenyl)-5-isopropyl derivative 8x, which possessed 30% of the in vitro activity of the potent fungal metabolite compactin (I). A molecular modeling analysis led to the description of a pharmacophore model characterized by (A) length limits of 5.9 and 3.3 A for the 2- and 5-substituents, respectively, as well as an overall width limit of 10.6 A across the pyrrole ring from the 2- to the 5-substituent and (B) an orientation of the ethyl(ene) bridge to the 4-hydroxypyran-2-one ring nearly perpendicular to the planes of the parent pyrrole, hexahydronaphthalene, and phenyl rings of the structures examined (Figure 3, theta = 80-110 degrees). Attempts to more closely mimic compactin's polar isobutyric ester side chain with the synthesis of 2-phenylpyrroles containing polar phenyl substituents resulted in analogues with equal or slightly reduced potencies when compared to the 2-[(unsubstituted or 4-fluoro)phenyl]pyrroles, supporting the hypothesis that inhibitory potency is relatively insensitive to side-chain polarity or charge distribution in this area.

  6-[2-lSubstituted-pyrrol-1-yl)alkyl]pyran-2-ones of formula I and the corresponding ring-opened hydroxy-acids derived therefrom are potent inhibitors of the enzyme 3-hydroxy-3-methylglutarylcoenzyme A reductase (HMG-CoA reductase), and are thus useful hypolipidemic and hypocholesterolemic agents. Pharmaceutical compositions containing such compounds. and a method of preparing the compounds are also disclosed.

  式 I 的 6-[2-取代-吡咯-1-基)烷基]吡喃-2-酮 及其衍生的相应开环羟基酸是 3-羟基-3-甲基戊二酰辅酶 A 还原酶（HMG-CoA 还原酶）的强效抑制剂，因此是有用的降血脂和降胆固醇药物。此外，还公开了含有此类化合物的药物组合物以及制备这些化合物的方法。
