Dimethyl fumarate (DMF) has an inhibitory effect on the production of pro-inflammatory proteins from different cells which participate in the immune reaction in psoriatic skin. Most recently it was shown that DMF is an allosteric covalent inhibitor of the p90 ribosomal S6 kinases (RSK1, 2), determined by X-ray crystallography. DMF binds to a specific cysteine residue in RSK2 and in the closely related mitogen and stress-activated kinases 1 (MSK1) which inhibits further downstream activation.
