N. Ohtake et al., 1-BETA-METHYL-2-(5-SUBSTITUTED PYRROLIDIN-3-YLTHIO) CARBAPENEMS .1. SYNTHESIS AND ANTIBACTERIAL ACTIVITY OF BO-2502A AND ITS RELATED-COMPOUNDS, Journal of antibiotics, 50(7), 1997, pp. 567-585
The synthesis and biological activity of (1R,5S,6S)-2-[(3S,5S)-5-subst
ituted pyrrolidin-3-ylthio]-6-[(R)- ydroxyethyl]-1-methyl-1-carbapen-2
-em-3-carboxylic acid, in which lactams and cyclic amines are introduc
ed as substituents, are described. They showed potent antibacterial ac
tivity against Gram-positive and Gram-negative bacteria including P. a
eruginosa. Among them, BO-2502A (4h-1) was selected for further evalua
tion.
