Abstract

We have described the synthesis, enzyme inhibitory activity, structure-activity relationships, and proposed binding mode of a novel series of pyrrole derivatives as lymphocyte-specific kinase (Lck) inhibitors. The most potent analogs exhibited good enzyme inhibitory activity (IC(50)s <10nM) for Lck kinase inhibition.
