Sialidases are key virulence factors that remove sialic acid from the host cell surface glycan, unmasking receptors that facilitate bacterial adherence and colonisation. In this study, we developed potential agents for treating bacterial infections caused by Streptococcus pneumoniae Nan A that inhibit bacterial sialidase using Turmeric and curcumin analogues. Design, synthesis, and structure analysis
唾液酸酶是关键的毒力因子,可从宿主细胞表面聚糖中去除唾液酸,从而暴露促进细菌粘附和定植的受体。在这项研究中,我们开发了治疗由肺炎链球菌 Nan A 引起的细菌感染的潜在药物,该药物使用姜黄和姜黄素类似物抑制细菌唾液酸酶。还描述了设计、综合和结构分析关系(SAR)研究。对合成衍生物的评估表明,化合物 5e 是肺炎链球菌唾液酸酶最有效的抑制剂(IC50 = 0.2 ± 0.1 µM)。该化合物的抑制活性比姜黄素提高了 3.0 倍,并表现出竞争性抑制作用。这些结果值得进一步研究证实抗肺炎球菌活性 5e 并表明姜黄素衍生物可能用于治疗细菌感染引起的脓毒症。
