title: Synthesis of some new Mannich bases derived from 6-acyl-3-(3,5-dimethylpiperidinomethyl)-2(3H)-benzoxazolones+ ++ and their biological activities.
abstract: A number of 6-acyl-3-(3,5-dimethylpiperidinomethyl)-2(3H)-benzoxazolones have been synthesized by Mannich reaction and their antibacterial and antifungal activities have been tested. Their chemical structures have been proved by means of their IR, NMR, mass spectroscopic data and by elementary analysis. Investigation of antimicrobial activity of compounds was done by tube dilution and paper disc techniques using bacteria (Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Staphylococcus faecalis RSKK 10541) and yeast-like fungi (Candida parapsilosis, Candida albicans, Candida pseudotropicalis, Candida stellatoidea). Among the compounds tested 6-(2-chlorobenzoyl)-3-(3,5-dimethylpiperidinomethyl)-2(3H)-benz oxazolone (Compound 2) and 6-(3-chlorobenzoyl)-3-(3,5-dimethylpiperidinomethyl)-2(3H)-benz oxazolone (Compound 3) showed the most favorable activity.
