Depeptidization efforts on α-ketoamide inhibitors of HCV NS3-4A serine protease: Effect on HCV replicon activity
摘要:
Depeptidization efforts of the P-3-P-2 region of P-3 capped alpha-ketoamide inhibitor of HCV NS3 serine protease I are reported. We clearly established that N-methylation of the P-2 nitrogen and modification of the P-2' carboxylic acid terminus were essential for activity in the replicon assay. (C) 2005 Elsevier Ltd.

trans-4-hydroxylpyrrolidine lactams 1 starting from amino acid is described. The utility of this method has been demonstrated in the synthesis of antipsychotic nemonapride 3 and antiangiogenic streptopyrrolidine 4. Compared four synthetic stereoisomers of natural streptopyrrolidine 4 in term of spectroscopic and physical data, the absolute structure of the natural product was proposed as (4S,5S)-configuration
