Abstract

Hydroxylated derivatives were designed and synthesized based on the information of oxidative metabolites. Compounds derived from beta-substituted (2R,3R)-2-amino-3-hydroxypropionic acid showed improved inhibitory activities against the binding of MIP-1alpha to human CCR5, compared with the non-hydroxylated derivatives and the other isomers.
