GtoPdb Ligand ID: 5269

Synonyms: PB 203580 | RWJ 64809 | SB-203580
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: SB203580 inhibits p38 MAPK enzymes, with some selectivity for p38α. The compound has been used to dissect the p38 signalling pathway and to determine the binding mode and differentiate functions between the four p38 MAP kinase homologues [4,6]. The hydrochloride salt is water-soluble.
