Yi. Lin et al., SYNTHESIS AND STRUCTURE-ACTIVITY RELATIONSHIPS OF NOVEL THF 1-BETA-METHYLCARBAPENEMS, Bioorganic & medicinal chemistry letters, 7(13), 1997, pp. 1671-1676
A series of twelve highly active aminomethyl-THF 1 beta-methylcarbapen
ems 3a-1 were synthesized. Of these, carbapenems 3a-f demonstrated a s
pectrum of antimicrobial activity comparable to those of imipenem and
meropenem with the exception of only moderate anti-pseudomonal activit
y. Most importantly, they demonstrated moderate intrinsic oral activit
y against an E. coli infection in mice. (C) 1997 Elsevier Science Ltd.
