A series of l-pyroglutamic acid analogues from natural product lead were designed and synthesized, as well as their antifungal activities against Phytophthora infestans, neuritogenic activities, antibacterial activities and anti-inflammatory activities are described. The bioassays and SAR study showed that the majority of l-pyroglutamic acid esters have a significant antifungal activity against P.
设计并合成了一系列来自天然产物铅的1-焦谷氨酸类似物,并描述了它们对疫霉菌的抗真菌活性,中枢神经活性,抗菌活性和消炎活性。生物测定和SAR研究表明,大多数1-焦谷氨酸酯类对P. infestans具有显着的抗真菌活性,尤其是2d和2j表现出最佳的活性,EC 50值为1.44和1.21μgmL -1,约为7倍于市售三氧化氮(7.85μgmL -1)。此外,化合物图2e,2g和4d显示了抗LPS诱导的BV-2小胶质细胞中NO产生的抗炎活性。NGF诱导的PC-12细胞中的神经生成活性是相同的。这项研究表明,化合物2d和2j是控制P. infestans的潜在药物。
