Improved antibacterial activities of coumarin antibiotics bearing 5′,5′-dialkylnoviose: biological activity of RU79115
摘要:
A new series of coumarin inhibitors of DNA gyrase B bearing a N-propargyloxycarbamate at C-3' of various 5',5'-dialkylnoviose, including RU79115, were synthesised and their antibacterial activities have been delineated. Introduction of dialkyl substituents at 5'5'-position of noviose leads to coumarin analogues with improved in vitro and in vivo antibacterial activity. (C) 2000 Elsevier Science Ltd.
