HIDE SMILES / InChI
Nemonoxacin is a non-fluorinated quinolone antibiotic in clinical development in an oral and intravenous formulation. It exhibits potent antibacterial activities against Gram-positive, Gram-negative, and atypical pathogens, especially methicillin-resistant Staphylococcus aureus. The molecule inhibits bacterial DNA synthesis by forming a ternary complex with a DNA molecule and gyrase and topoisomerase IV enzymes, thus blocking bacterial DNA supercoiling. Nemonoxacin is developed by TaiGen Biotechnology Company and has reached worldwide approval in 2014 and is marketed under the name Taigexyn®.
