Design, synthesis and antifungal activity of novel indole derivatives linked with the 1,2,3-triazole moiety via the CuAAC click reaction

摘要

A series of novel indole derivatives linked with the 1,2,3-triazole moiety was designed, synthesised by the CuCl2/Zn-catalysed Huisgen cycloaddition and characterised. The antifungal activity of all the prepared compounds against Colletotrichum capsici and cotton Physalospora pathogens was evaluated and the results indicated that these compounds showed inhibitory effect for fungi and the inhibition ratio of the best was up to 83.3%. The preliminary structure-activity relationship is also discussed in this paper.
