GtoPdb Ligand ID: 9380

Synonyms: BIX 02189 | BIX-02189
Compound class: Synthetic organic
Comment: BIX02189 is an experimental, small molecule inhibitor of mitogen-activated protein kinase kinase 5 (MEK5; MAP2K5) [1]. It is more potent than BIX02188, described in the same article. Also inhibits ERK5 (MAPK7).

Bioactivity Comments
BIX02189 also inhibits catalytic activity of ERK5 (mitogen-activated protein kinase 7; MAPK7), but does not inhibit closely related kinases MEK1, MEK2, ERK2, and JNK2. In a wider kinase screening panel BIX02189 inhibited RPS6KA6 (RSK4) by 94%, RPS6KA3 (RSK2) by 88%, p90RSK by 52%, LCK by 94%, KIT by 69%, JAK3 by 55%, FGFR1 by 76%, CSF1R (FMS) by 96% and ABL by 81%.
BIX02189 inhibits phosphorylation of ERK5 and activation of the downstream transcription factor target MEF2C (myocyte-specific enhancer factor 2C) [1].
