摘要

This letter describes the structure-activity relationship (SAR) of the 'right-wing' α-amino acid residue of potent tetrahydroisoquinoline (THIQ)-derived LFA-1/ICAM-1 antagonists. Novel (S)-substituted heteroaryl-bearing α-amino acids have been identified as replacements of the 'right-wing' (S)-2,3-diaminopropanoic acid (DAP) moiety. Improvement of potency in the Hut-78 assay in the presence of 10% human serum has also been achieved.Copyright © 2010 Elsevier Ltd. All rights reserved.
