Peptidic prodrugs of novel aminomethyl-THF 1β-methylcarbapenems
摘要:
Peptidic prodrugs of the five most active aminomethyl-THF 1 beta-methylcarbapenems were synthesized. Of these, only L-amino acid derivatives from la demonstrated an improved oral activity. These results indicate that the L-amino acid derivatives from la are orally absorbed most likely through the dipeptide and tripeptide transport mechanism. (C) 1997 Elsevier Science Ltd.
Synthesis and structure-activity relationships of novel THF 1β-methylcarbapenems
摘要:
A series of twelve highly active aminomethyl-THF 1 beta-methylcarbapenems 3a-1 were synthesized. Of these, carbapenems 3a-f demonstrated a spectrum of antimicrobial activity comparable to those of imipenem and meropenem with the exception of only moderate anti-pseudomonal activity. Most importantly, they demonstrated moderate intrinsic oral activity against an E. coli infection in mice. (C) 1997 Elsevier Science Ltd.
