Abstract

2-(5-Nitro-2-imidazolylmethylene)-1-indanones, -1-tetralones, and -acetophenones substituted by aminoalkoxy groups and related compounds (41-69, table ii) were synthesized and their antimicrobial activities were evaluated (table iii). Some of these compounds (e.g. 47, 52, and 59) suprisingly exhibited a broad antibacterial spectrum including Proteus species and Pseudomonas aeruginosa. Extraordinary antitrichomonal activities could also be observed in vitro (MIC of compound 59, 0.0004 pg/ml) and six of the title compounds (48, 49, 52, 58, 64, 66) displayed in vivo activity in mice against Trichomonas vaginalis comparable to that of metronidazole (70).
