Task: Answer the following question about the molecule with SMILES COC(=O)/C=C/C(=O)O.
Request: Please describe this drug.
Answer: Monomethyl fumarate is a dicarboxylic acid monoester resulting from the formal condensation of one of the carboxy groups of fumaric acid with methanol. Is is a metabolite of dimethyl fumarate and used for the the treatment of patients with relapsing multiple sclerosis (MS). It also induces the NFE2L2 (Nrf2) transcription factor by binding to KEAP1. It has a role as an immunomodulator, an antioxidant and a drug metabolite. It is an enoate ester, a methyl ester and a dicarboxylic acid monoester. It is functionally related to a fumaric acid.
