One-pot synthesis of new triazole-sucrose derivatives via click chemistry and evaluation of their antitubercular activity

Abstract

Readily prepared copper nanoparticles are an effective catalyst for 1,3-dipolar cycloaddition of carbohydrate azide and a variety of alkynes that furnishes the corresponding 1,2,3-triazole-sucrose derivatives in excellent yields. Products were screened for their antimycobacterial activity against Mycobacterium tuberculosis H37Rv strain. Two compounds, 3b,c, demonstrate significant growth inhibitory activity against the bacterial strain with a MIC of 3.125 mg/mL. The presence of an amide group on the 1,2,3-triazole ring enhances the inhibition activity of the molecules. The active compounds are not toxic to a normal cell line which signifies the lack of general cellular toxicity of these compounds.
