Studies on isoquinoline derivatives. IV. Synthesis and evaluation of the antimicrobial and antifungal activities of N2-arylidene-substituted 3-carbazoyl-isoquinolines.
2,4-Dimethyl-1-oxo-1,2-dihydro-3-carbazoyl-isoquinoline (II), 1-chloro-, 1-methoxy-3-carbazoyl-4-methylisoquinoline (VI, X) and a series of their hydrazonic derivatives have been synthesized and tested in vitro for antibacterial and antifungal activities. 1-(1-Chloro-4-methyl-3-isoquinolinoyl)-2-(5-nitro-2-furfurylide ne) hydrazine (VII h) proved to be the most effective in the series (MIC 0.78 micrograms/ml) and was more potent than furazolidone against several strains of S.aureus; the same compound also showed a moderate antifungal activity.
