Abstract
1-Benzhydryl -4- (5-nitro-2-furfurylideneamino) piperazine and 11 substituted analogs were prepared and examined for in vitro antimicrobial activity. The compounds were active against Bacillus cereus 7, Bacillus megaterium 122, Bacillus subtilis 104, Clostridium perfringens 13, and the tetracycline-resistant Clostridium perfringens 37. Regression analyses on the antibacterial activity data based on the Hansch approach, using pi, pi2, and sigma parameters, yielded several statistically significant correlation equations. 1-Benzhydryl-4-(5-nitro-2-furfurylideneamino) piperazine stopped the protein and DNA syntheses in C. perfringens 13, as indicated by precipitable radioactivity. The compound, however, showed no effect on the cell wall synthesis in the bacteria.
