A series of novel phenyl-substituted 2-(1H)-quinolone compounds have been prepared, including the 3,4-dihydro derivatives thereof, wherein the phenyl ring moiety is a mono-or di-substituted phenyl group attached to the 5-, 6-, 7- or 8-positions of the quinolone ring. These particular compounds are useful in therapy as highly potent inotropic agents and therefore, are of value in the treatment of various cardiac conditions. Preferred member compounds include 8-methyl-6-[4-methylsulphinylphenyl]-2-(1H)-quinolone, 8-methyl-6-[4-hydroxyphenyl]-2-(1H)-quinolone and 8-methyl-6-[4-carbamoylphenyl]-2-(1H)-quinolone, respectively. Methods for preparing these compounds from known starting materials are provided.
已经制备了一系列新颖的苯基取代的2-(1H)-喹啉化合物,包括其3,4-二氢衍生物,其中苯环基团是连接到喹啉环的5-、6-、7-或8-位置的单取代或双取代苯基团。这些特定化合物在治疗中具有高度有效的正性肌力作用,因此在治疗各种心脏病症方面具有价值。首选成员化合物包括8-甲基-6-[4-甲基砜基苯基]-2-(1H)-喹啉、8-甲基-6-[4-羟基苯基]-2-(1H)-喹啉和8-甲基-6-[4-氨基甲酰基苯基]-2-(1H)-喹啉。提供了从已知起始材料制备这些化合物的方法。
