study antifungal activities. In vitro and in vivo antifungal activity results revealed that compounds 2-25, which contain a γ-butyrolactone scaffold and cinnamic aldehyde moiety, have greater potent fungicidal activity than other compounds. The preliminary structure–activity relationships (SARs) demonstrated that compounds with electron-withdrawing groups and small steric hindrance would have more desirable
鉴于倍半萜烯内酯和天然产物郁金香菌肽A具有很大的抗真菌活性,合成了52种衍生自α-亚甲基-γ-丁内酯亚结构的衍生物,以研究其抗真菌活性。体外和体内抗真菌活性结果表明,包含2-γ-丁内酯支架和肉桂醛部分的化合物2-25具有比其他化合物更大的有效杀真菌活性。初步的结构-活性关系(SAR)表明,具有吸电子基团和小的位阻的化合物将具有更理想的效价。同时,定量构效关系(QSAR)模型(R 2 = 0.947,F= 65.77,和S 2= 0.0028)表明针对灰葡萄双歧杆菌的抗真菌活性与标题化合物的分子结构具有令人信服的相关性。本研究为α-亚甲基-γ-丁内酯亚结构的抗真菌活性提供了更详细的见识,这为探索农业中的α-烯基-γ-丁内酯结构提供了潜在的期望。
