摘要:
The invention relates to derivatives of group B streptogramins of general formula (I), wherein R, R1, Ra, Rb, Rc and Rd have the meanings given in the description. Said derivatives are particularly suitable for use as antimicrobial agents, optionally coupled with at least one group A streptogramin derivative.
摘要:
The invention concerns 4-substituted quinoline derivatives active as antimicrobial agents, of general formula (I), wherein: X1, X2, X3, X4 and X5 respectively represent >C-R'1 to >C-R'5, or not more than one represents N; Y represents CHR, CO, CROH, CRNH2, CRF or CF2, R being hydrogen or alkyl; m is 1, 2, or 3 and n is 0, 1 or 2; Z is CH2 or Z represents O, S, SO, SO2 and, in that case, n is equal to 2; R2 represents -CO2R, -CH2CO2R, -CH2-CH2CO2R, -CH2OH or -CH2-CH2OH, R being as defined above; R3 represents phenyl, heteroaryl or alk-R°3, wherein alk is an alkyl and R°3 represents various groups, optionally oxygenated, sulphured or aminated, in their enantiomeric or diastereoisomeric forms or mixtures thereof, and optionally in their syn or anti forms or mixtures thereof, as well as their salts.
