synthesized compounds 4a, 4b, 4c to 7a, 7b, 7c were characterized using IR, NMR, and MS Spectroscopy. Some of the synthesized compounds 4,5,7a, 7b, 7c were evaluated for their antibacterial and antifungal activities. Most of these compounds indicated activity comparable to Gentamycine. Also some of them are more active than Tolnaftate, a known antifungal drug. J. Heterocyclic Chem., (2011)
通过2,4-二氢-4-苄基-5-(吡啶基)-3H-1,2,4-的反应合成了带有吡唑(或恶二唑)环的取代的1,2,4-三唑的几种衍生物在无水乙醇中的三唑-3-硫酮1a,1b,1c与氯乙酸乙酯,水合肼和乙酰丙酮(或CS 2 / KOH)一起使用。然后该中间体在酸性介质中经历分子内环化。使用IR,NMR和MS光谱对新合成的化合物4a,4b,4c至7a,7b,7c进行表征。一些合成的化合物4,5,图7a,图7b,图7c分别对它们的抗菌和抗真菌活性进行评价。这些化合物大多数显示出与庆大霉素相当的活性。它们中的一些还比已知的抗真菌药Tolnaftate更具活性。J.杂环化学。(2011)
