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.
p-Nitrobenzyloxycarbonyl (pNZ) as a TemporaryNα-Protecting Group in Orthogonal Solid-Phase Peptide Synthesis - Avoiding Diketopiperazine and Aspartimide Formation
p-Nitrobenzyloxycarbonyl (pNZ) was used as a temporary protectinggroup for α-amino functionalities in solid-phase peptide synthesis. The corresponding derivatives are readily synthesized solids that perform well on solid phase. The pNZ moiety is orthogonal with the most common protectinggroups used in peptide chemistry, and is removed under neutral conditions in the presence of catalytic amounts
