Microwave assisted one pot synthesis of some novel 2,5-disubstituted 1,3,4-oxadiazoles as antifungal agents
摘要:
Sodium bisulfite has been reported first time for the synthesis of 2,5-disubstituted 1,3,4-oxadiazole using microwave and conventional method in ethanol-water. The yields obtained are in the range of 90-95% using microwave and 87-91% using conventional method. All the synthesized compounds (8a-8s) are novel and were evaluated for their in vitro antifungal activity. SAR for the series has been developed by comparing their MIC values with miconazole and fluconazole. Some of the compounds from the series like 8k was equipotent with miconazole against Candida albicans and Fusarium oxysporum. Also compound 8n was equipotent with miconazole against F. oxysporum.

Synthesis of new series of 1,2,4‐triazole with 1,2,3‐triazole and piperidine ring using ZrOCl2·8H2O as a catalyst in ethanol has been described. The yields obtained are in the range of 80–85%. All the synthesized compounds (3a–3o) are novel and were evaluated for their in vitro antifungal activities using standard agar method. Docking study of the newly synthesized compounds was performed, and results

An improved protocol for the synthesis of a novel series of 1,2,4-triazines possessing 1,2,3-triazole and piperidine ring using 1-(1-substituted piperidin-4-yl)-1H-1,2,3-triazole-4-carbohydrazide, benzil, ammonium acetate and ZrOCl2 center dot 8H(2)O as a catalyst in ethanol-water has been presented. The yields obtained are in the range of 87-94%. All the synthesized compounds (4a-4l) are novel and were evaluated for their in vitro antifungal activity. SAR for the series has been developed by comparing their MIC values with miconazole and fluconazole. Based on activity data SAR for the series has been developed. Compound 4c from the series was equipotent to miconazole against Candida albicans (MIC-25), Aspergillus niger (MIC-12.5) and Cryptococcus neoformans (MIC-25). Compound 4d was equipotent with miconazole against all tested organisms except Cryptococcus neoformans. Also compound 4i was equipotent with miconazole against C. albicans, A. niger and Fusarium oxysporum. (C) 2009 Elsevier Ltd. All rights reserved.
