As part of our continuing research on canthin-6-one antimicrobial agents, a new series of ester derivatives of 10-hydroxycanthin-6-one were synthesized using a simple and effective synthetic route. The structure of each compound was characterized by NMR, ESI-MS, FT-IR, UV, and elemental analysis. The antimicrobial activity of these compounds against three phytopathogenic fungi (Alternaria solani, Fusarium
作为我们对canthin-6-one抗菌剂的持续研究的一部分,使用一种简单有效的合成途径合成了一系列新的10-hydroxycanthin-6-one的酯衍生物。通过NMR,ESI-MS,FT-IR,UV和元素分析对每种化合物的结构进行表征。使用菌丝体线性生长速率法和微量化学方法评估了这些化合物对三种植物病原真菌(Alternaria solani,禾谷镰刀菌和Fusarium solani)和四种细菌(蜡状芽孢杆菌,枯草芽孢杆菌,枯草芽孢杆菌,丁香假单胞菌和丁香假单胞菌)的抗菌活性。肉汤稀释法。讨论了构效关系。在测试的化合物中,4和7s对禾谷镰刀菌具有显着的抗真菌活性,在浓度为50μg/ mL时抑制率为100%。化合物5、7s和7t对所有测试细菌表现出最佳的抑制活性,最小抑制浓度(MIC)在3.91和31.25μg/ mL之间。因此,7s成为开发新型Canthine-6-one抗菌剂的有前途的先导化合物。
