A newseries of beta amino acids, which act as CXCR3 antagonists, has been identified. The formerly optimized N,N-disubstituted benzylamine derivatives with carboxylic acid function on the N-atom was used as starting point and compounds with carboxyl function not attached to the N-atom were investigated. Affinity, metabolic stability in human and mouse liver microsomes and Caco-2 permeability were
Aromatic β-amino acid esters 2a-h were prepared in racemic and enantiomerically pure form by the Radionow reaction or based on the method described by Davis and used as mimics of the Asp-Phg C-terminus in LDV derived VLA-4 antagonists. As a promising β-amino acid ester, 11 was identified and used for the synthesis of the highly potent VLA-4 antagonist S9059 with an IC50 of 1.6 nM in a cell attachment assay.
