    For the search of the more active antimicrobial compounds than the 2, 6-disubstituted derivatives, 3, 6-disubstituted 2, 3, 6, 9-tetrahydro-2, 9-dioxothiazolo [5, 4-f] quinoline-8-carboxylic acid (1, 3, 7, 8, 11, 20, 21, and 22) were synthesized from the 2-oxo-6-substituted thiazolo [5, 4-f] quinoline derivatives (2, 17, or 18). Thermal rearrangement of the 2-methylthio derivative (23) gave the 2-thioxo-3-methyl derivative (24), which was converted into the 2-oxo-3-methyl derivative (26) by reaction with mercuric acetate. The 2-ethoxy derivative (27) was also thermally rearranged to give the 2-oxo-3-ethyl derivative (8b). The 3, 6-disubstituted compounds obtained in this work showed the stronger activities against gram-negative and gram-positive bacteria in vitro than nalidixic acid and the 2, 6-disubstituted derivatives prepared in the previous work. 6-Ethyl-2, 3, 6, 9-tetrahydro-3-methyl-9-oxothiazolo [5, 4-f] quinoline-8-carboxylic acid (8a) exhibited the strongest activities among these compounds against many gram-negative bacteria including E. coli resistant to nalidixic acid and Ps. aeruginosa, and against some gram-positive bacteria.
    为了寻找比2,6-取代衍生物更活跃的抗微生物化合物,合成了3,6-取代的2,3,6,9-四-2,9-二噻唑[5,4-f]喹啉-8-羧酸(1、3、7、8、11、20、21和22),这些化合物是从2--6-取代噻唑[5,4-f]喹啉生物(2、17或18)合成的。2-甲基生物(23)的热重排反应生成了2--3-甲基生物(24),该衍生物醋酸反应转化为2--3-甲基生物(26)。2-醇乙基衍生物(27)也经过热重排生成了2--3-乙基衍生物(8b)。本研究中获得的3,6-取代化合物在体外对革兰阴性菌和革兰阳性菌的活性较之前工作中制备的喹诺酮酸和2,6-取代衍生物更强。6-乙基-2,3,6,9-四-3-甲基-9-噻唑[5,4-f]喹啉-8-羧酸(8a)在这些化合物中对包括对喹诺酮酸耐药的大肠杆菌和绿假单胞菌在内的多种革兰阴性菌,以及对一些革兰阳性菌表现出最强的活性。
