摘要:
This letter describes the structure-activity relationship (SAR) of the 'right-wing' alpha-amino acid residue of potent tetrahydroisoquinoline (THIQ)-derived LFA-1/ICAM-1 antagonists. Novel (S)-substituted heteroaryl-bearing alpha-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. (C) 2010 Elsevier Ltd. All rights reserved.
