Fraxidin is a class of coumarin. It is isolated from the roots of Jatropha podagrica. It also shows antibacterial activity against Bacillussubtilis with an inhibition zone of 12 mm at a concentration of 20 µg disk.
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。
Tuberine, (+)- is an alkaloid isolated from Haplophyllum tuberculatum that has high antimicrobial activity against Staphylococcus aureus, Bacillussubtilis and Saccharomyces cerevisiae. Tuberine, (+)- is also slightly inhibitory to Escherichia coli .
Antibiotic MA 144M2 is an anthracycline glycoside that inhibits the growth of gram-positive bacteria, e.g. Staphyococcus aureaus, Bacillussubtilis and Sarcina lutea, and inhibits the growth of animal tumors such as leukemia L 1210, P 388 and sarcoma 180. It's produced by fermentation of MA 144-producing strains of streptomyces and by the chemical or enzymatic conversion of aclacinomycin A or cinerubin A.
