Synthesis and structure-activity relationships of novel arylfluoroquinolone antibacterial agents
摘要:
A series of novel arylfluoroquinolones has been prepared. These derivatives are characterized by having a fluorine atom at the 6-position, substituted amino groups at the 7-position, and substituted phenyl groups at the 1-position. Structure-activity relationship (SAR) studies indicate that the in vitro antibacterial potency is greatest when the 1-substituent is either p-fluorophenyl or p-hydroxyphenyl and the 7-substituent is either 1-piperazinyl, 4-methyl-1-piperazinyl, or 3-amino-1-pyrrolidinyl. The electronic and spatial properties of the 1-substituent, as well as the steric bulk, play important roles in the antimicrobial potency in this class of antibacterials. As a result of this study, compounds 45 and 41 were found to possess excellent in vitro potency and in vivo efficacy.
Quinoline compounds having the formula:
wherein R is an phenyl group or an aromatic heterocyclic group, Z is an aliphatic heterocyclic group or an amine, and R1 is hydrogen or a carboxy-protecting group. The compounds here disclosed have antibacterial properties.
