The synthesis and properties of some new 7-cyclopropyl-4,7-dihydro-4-oxothieno[2,3-b]pyridine-5-carboxylic acids and the 7-tert-butyl analogues, incorporating substituents at positions 2 and 3, are described. The antibacterial activity of these derivatives and of the parent 7-alkyl-2-chloro compounds, unsubstituted at position 3, has been evaluated against an assortment of micro-organisms. 2-Chloro-7-cyclopropyl-4
一些新的 7-环丙基-4,7-二氢-4-氧代噻吩并[2,3-b]吡啶-5-羧酸和 7-叔丁基类似物的合成和性质,在 2 和 3 位加入取代基,被描述。这些衍生物和 3 位未取代的母体 7-烷基-2-氯化合物的抗菌活性已针对各种微生物进行了评估。2-Chloro-7-cyclopropyl-4,7-dihydro-4-oxothieno[2,3-b]pyridine-5-羧酸 (3a) 被发现在 4-thieno[2,3- b]迄今为止已知的普利酮。然而,3-硝基-或 3-氨基-2-(4-methyl-1-piperazinyl) 衍生物 (4-6) 都没有表现出有趣的抗菌活性。
