in Streptococcus agalactiae (Group B Streptococcus , GBS). Their significant impacts on biofilm formation were examined via SEM to reveal early‐stage inhibition of cellular adhesion. Additionally, the synthetic glycosides were evaluated against five of the six ESKAPE pathogens and two fungal pathogens. These studies reveal that the ellagic acid glycosides possess inhibitory effects on the growth of
鞣花酸衍生物对多种微生物病原体具有抗菌和抗生物膜特性。由于它们的溶解性差和反应性差,因此合成、纯化和表征鞣花酸糖苷的活性具有挑战性。在这项研究中,我们合成了三种鞣花酸糖缀合物,并评估了它们在无乳链球菌(B 组链球菌)中的抗菌和抗生物膜活性。, GBS)。通过 SEM 检查它们对生物膜形成的显着影响,以揭示细胞粘附的早期抑制。此外,还针对六种 ESKAPE 病原体中的五种和两种真菌病原体对合成糖苷进行了评估。这些研究表明,鞣花酸苷对革兰氏阴性病原体的生长具有抑制作用。
