Function

CD44_MOUSE Main cell surface receptor for hyaluronate. Adhesion to mucosal high endothelial venule and to types I and VI collagen. Probably involved in matrix adhesion, lymphocyte activation and lymph node homing.

Publication Abstract from PubMed

Selective inhibitors of hyaluronan (HA) binding to the cell surface receptor CD44 will have value as probes of CD44-mediated signaling and have potential as therapeutic agents in chronic inflammation, cardiovascular disease, and cancer. Using biophysical binding assays, fragment screening, and crystallographic characterization of complexes with the CD44 HA binding domain, we have discovered an inducible pocket adjacent to the HA binding groove into which small molecules may bind. Iterations of fragment combination and structure-driven design have allowed identification of a series of 1,2,3,4-tetrahydroisoquinolines as the first nonglycosidic inhibitors of the CD44-HA interaction. The affinity of these molecules for the CD44 HA binding domain parallels their ability to interfere with CD44 binding to polymeric HA in vitro. X-ray crystallographic complexes of lead compounds are described and compared to a new complex with a short HA tetrasaccharide, to establish the tetrahydroisoquinoline pharmacophore as an attractive starting point for lead optimization.
