摘要: 目的 合成查耳酮类化合物并测定其抗真菌活性。方法 利用Claisen-Schmidt反应合成查耳酮,并针对四种真菌(白色念珠菌、新生隐球菌、烟曲霉菌、红色毛癣菌)做了体外抗真菌活性筛选。结果 显示所合成化合物大多具有体外抗真菌活性,尤其化合物8, 其针对浅表菌的抗真菌活性与氟康唑相当。本文还对部分查耳酮的合成做了一些探索。结论 所合成的查耳酮均有不同程度的抗真菌活性,其化学结构差异与抗菌活性相关。

Abstract: Aim To study the antifungal effect of chalcone derivatives. Methods Sixteen chalcone derivatives were synthesized and confirmed by 1H NMR and IR spectra, and tested for antifungal activity against four common pathogenic fungi. Their structure-activity relationship is discussed. Results Among 16 title compounds, there were 5 new compounds, which have not been reported before. The preliminary antifungal test showed that all title compounds exhibited antifungal activities to a certain extent. The activity of compound 8 against Trichophyton rubrum had a potency equal to that of fluconazole, with a MIC of 4 μg·mL-1. Conclusion Sixteen chalcones were prepared and their antifungal activities against four common pathogenic fungi in vitro were examined. Some of them exhibited antifungal activities to a certain extent.
