KKL-40 是一种小分子抑制剂,专门针对反式转录过程,能够有效抑制甲氧西林敏感和耐药的金黄色葡萄球菌 (S. aureus),以及包括耐万古霉素的屎肠球菌、枯草芽孢杆菌和化脓性链球菌在内的其他革兰氏阳性病原体。KKL-40 与人类抗菌肽 LL-37 协同作用可抑制金黄色葡萄球菌,但与达托霉素、卡那霉素或红霉素等其他抗生素之间没有协同效应。反式转录是一种极端的重新编码形式,KKL-40 能抑制该过程,同时对 HeLa 细胞无毒。
CAY10766 is an antiviral compound.1It inhibits entry of influenza virus-like particles pseudotyped with hemagglutinin A (HA) from H5N1 influenza A virus into A549 cells (EC50= 0.24 μM). CAY10766 (1 μM) reduces H1N1 and H5N1 influenza A viral titers in infected MDCK cells. It also exhibits synergy with oseltamivir carboxylate in MDCK cells infected with the influenza A reporter PR8-NS1-Gluc virus.
Desacetyl cefapirin is an active metabolite of the cephalosporin antibiotic cefapirin .1 Desacetyl cefapirin is active against E. coli, K. pneumoniae, P. mirabilis, and S. aureus with MIC values of 120, 24, 34, and 0.42 μg ml, respectively.References1.
