Abstract

To elucidate further our structural activity relation on the chemistry and antimicrobial activity, a series of novel N-alkylated benzotriazole derivatives bearing pharmaceutically important substituted biphenyl and benzyl halides were synthesized. The synthesized compounds were characterized and tested for in vitro antimicrobial activities by MIC determination against a panel of susceptible and resistant Gram-positive and Gram-negative microorganisms. The synthesis has been carried out using microwave irradiation method with solvent and without solvent. The obtained results showed high yields. Interestingly, compounds 2a and 2b showed a two fold increased antibacterial activity than the standard drug tested and the compounds 2d and 2e showed potent antifungal activity than the standard drug tested.
