Kosugi et al. In this manner of operation, the overall process efficiency is significantly increased. The diamines are condensed with phosgene to give methylene diphenyl diisocyanatea precursor to urethane polymers. The compounds bearing nitro groups were found to have significant potential against all bacterial strains. This may be due to the large difference between the values of physicochemical parameters calculated for target compounds with values of parameters calculated for standard drugs. Synthesis and evaluation of some novel derivatives of 2-propoxybenzylideneisonicotinohydrazide for their potential antimicrobial activity. Webb
