Abstract

Unambiguous identification of the E-selectin antagonist 1 in a mixture of potential E-selectin ligands is possible with a bioactivity assay that is based on transfer NOE. This is remarkable, since the compounds present in the mixture have similar structures and their 1H NMR signals overlap extensively.
