compounds, 3- O-acyl-(-)-epicatechins and 3- O-acyl-(+)-catechins possessing various aromatic groups and aliphatic chains of varying length from C4 to C16 for increasing lipophilicity were synthesized and tested for antimicrobial activities against Gram-positive, Gram-negative bacteria and fungi. The (-)-epicatechin and (+)-catechin derivatives comprised of aromatic groups increased activity and derivatives
作为抗菌促进化合物的探索性研究,3-O-酰基-(-)-表儿茶素和3-O-酰基-(+)-儿茶素具有不同的芳香族基团和从C4到C16的不同长度的脂族链,以增加亲脂性。合成并测试了对革兰氏阳性,革兰氏阴性细菌和真菌的抗菌活性。由芳族基团组成的(-)-表儿茶素和(+)-儿茶素衍生物的活性增强,并且在C8至C10的附近具有碳原子酰基链基的衍生物表现出很强的抗菌活性(MIC = 2-8 microg / ml)抵抗革兰氏阳性细菌,抗真菌活性弱。然而,当取代基的碳链长度太短(C4至C6)或太长(C16)时,活性降低。
