Ch. Oh et al., Synthesis and antibacterial activity of 1 beta-methylcarbapenem having a 1,3-diazabicyclo[3.3.0]octan-4-one moiety, part II, ARCH PHARM, 332(4), 1999, pp. 111-114
The synthesis of a new series of 1 beta-methylcarbapenems having a 1,3-diaz
abicyclo[3.3.0]octan-4-one moiety is described. Their in vitro antibacteria
l activities against both Gram-positive and Gram-negative bacteria are test
ed and the effect of substituent on the bicyclic ring was investigated. A p
articular compound (11h) having aminoethyl group showed the most potent ant
ibacterial activity.
