  Design, synthesis and antifungal activities of novel 1,2,4-triazole derivatives

  摘要：

  A series of novel 1,2,4-triazole derivatives with a 4-(4-substitutedphenyl) piperazine side chain were designed and synthesized based on the structure of lanosterol 14 alpha-demethylase (CYP51). Their antifungal activities against eight human pathogenic fungi were evaluated in vitro by measuring the minimal inhibitory concentrations. Nearly all tested compounds were found to be more potent against Candida albicans than control drug fluconazole. Noticeably, the MIC80 value of compounds 6,7,9,14 and 29 is 16 times lower than that of voriconazole against C. albicans. The activities of compounds 7 and 21 against Cryptococcus neoformans in vitro are comparable to that of voriconazole with a MIC80 value of 0.0156 mu g/mL. Moreover, the molecular model for the binding between compound 7 and the active site of CACYP51 was provided based on the computational docking results. (C) 2011 Elsevier Masson SAS.

  A series of 1-(1H-1,2,4-triazol-1-yl)-2-(2,4-difluorophenyl)-3-[(4-substitutedphenyl)-piperazin-1-yl]-prop n-2-ols have been designed and synthesized on the basis of the structure-activity relationships and antimycotic mechanism of azole antifungal agents. Their structutes were confirmed by elemental analysis, IR, MS, H-1 NMR and 13 C NMR. Results of preliminary antifungal tests against six human pathogenic fungi (Candida albicans, Candida parapsilosis, Cryptococcus neoformans, Candida tropicalis, inherently fluconazole-resistant Candida krusei, Candida glabrata) in vitro showed that all title compounds exhibited activity against fungi tested to some extent except against C. tropicalis. Compound 5b showed higher activity against C. albicans, C. parapsilosis and C. krusei than fluconazole, and its MIC values were determined to be 0.5 mu g/mL, 1 mu g/mL and 4 mu g/mL, respectively. Compound 5k showed higher activities against Torulopsis glabrata than fluconazole (with the MIC value of 2 mu g/mL). Compounds 5a, 5c, 5f, 5g, 5i exhibited higher activities against C. parapsilosis than fluconazole (with the MIC. values of 2 mu g/mL, 2 mu g/mL, 2 mu g/mL, 1 mu g/mL and 2 mu g/mL, respectively).
