A series of substituted quinoline mevalonolactones were prepared and evaluated for their ability to inhibit the enzyme HMG-CoA reductase both in vitro and (cholesterol biosynthesis) in vivo. Since previous studies suggested that the 4-(4-fluorophenyl) and 2-(1-methylethyl) substituents afforded optimum potency, attention was focused on variations at position 6 of the quinoline ring. Biological evaluation
制备了一系列取代的喹啉甲戊内酯,并评估了它们在体外和体内(胆固醇生物合成)抑制HMG-CoA还原酶的能力。由于先前的研究表明4-(4-氟苯基)和2-(1-甲基乙基)取代基具有最佳效价,因此将注意力集中在喹啉环的6位上。对带有多种6-取代基的少量类似物的生物学评估表明,在此位置进行修饰对效价影响很小。鉴定了几种化合物(8b,8e和11),它们在体外和体内试验中均显示出与Compactin和mevinolin相当的效价。
