title: Antimicrobial activity of some substituted triazoloquinazolines.
abstract: Fifteen substituted 1,2,4-triazolo[4,3-c]quinazolines were tested for antibacterial and antifungal effects. The most effective derivatives had the triazoloquinazoline skeleton substituted with the pharmacologically active chromophores--morpholine, chlorine and nitro group. The broadest antimicrobial activity was found with 5-morpholin-4-yl-3-(5-nitrothien-2-yl)[1,2,4]triazolo[4,3-c]quinazoline in concentration of 10 mg/L for B. subtilis, 50 mg/L for S. aureus and 100 mg/L for C. tropicalis. The highest tested concentration of derivative caused 83% growth inhibition of R. nigricans.
