NSC 55655 (5-[(2-Nitrophenyl)methylene]-2,4-thiazolidinedione) 具有抗菌和抗氧化活性,抑制 B. subtilis, S. aureus, K. pneumonia, E. coli, S. typhi ,A. niger 和 C. albicans 的增殖,可用于糖尿病。
Hirsutide is a cyclotetrapeptide fungal metabolite produced by the entomopathogenic fungus Hirsutella. It has antibacterial activity against C. pyogenes, S. aureus, P. aeruginosa, and K. pneumonia (MICs = 25, 13, 6, and 21 μg/cm3, respectively). Hirsutide also has antifungal activity against C. albicans, M. audouinii, A. niger, and Ganoderma (MICs = 13, 6, 25, and 6 μg/cm3, respectively).
Antibacterial agent 111 (Compound 3) exhibits potent antibacterial activity against B. cereus and K. pneumonia, with MIC values of 3.90 μg mL and 0.49 μg mL, respectively. It achieves this antibacterial effect by strongly binding to specific residues of tyrosyl-tRNA synthetase [1].
