A series of novel heterocyclic-substituted 2-(1H)-quinolone compounds have been prepared wherein the heterocyclic ring moiety is a substituted pyrrolyl, imidazolyl, pyrazolyl, triazolyl or tetrazolyl group attached by a nitrogen atom of said group to the 5-, 6-, 7- or 8-positions of the quinolone ring. These particular compounds are useful in therapy as highly potent cardiac stimulants and therefore, are of value in the treatment of various cardiac conditions. Typical member compounds include those 6-(heterocyclic-substituted)-8-methyl-2-(1H)-quinolones wherein the heterocyclic ring moiety is a ring-substituted imidazol-1-yl group and preferably, an imidazol-1-yl group substituted with one or two methyl groups and a monoacetyl group. 6-(4-Acetyl-2-methylimidazol-1-yl)-8-methyl--2-(1H)-quinolone represents a typical and preferred member compound. Methods for preparing all these compounds from known starting materials are provided.
已制备了一系列新颖的杂环取代的2-(1H)-喹啉化合物,其中杂环环基是通过氮原子连接到喹啉环的5-、6-、7-或8-位置的取代吡咯基、咪唑基、吡唑基、三唑基或四唑基。这些特定化合物在治疗中具有高效的心脏刺激作用,因此在治疗各种心脏疾病方面具有价值。典型的成员化合物包括那些6-(杂环取代)-8-甲基-2-(1H)-喹啉,其中杂环环基是取代的咪唑-1-基团,最好是一个或两个甲基基团和一个单乙酰基团取代的咪唑-1-基团。6-(4-乙酰-2-甲基咪唑-1-基)-8-甲基-2-(1H)-喹啉代表一个典型和首选的成员化合物。提供了从已知起始物质制备所有这些化合物的方法。
