GtoPdb Ligand ID: 9844

Synonyms: Formula (10) [WO2012078708A1]
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: CH-4051 is an orally available methotrexate (MTX) analogue that is designed to resist metabolic degradation [4-5]. This strategy was employed to improve the safety and tolerability profile compared to MTX, since a significant proportion of the toxicity profile of MTX can be attributed to its polyglutamylated and hydroxylated metabolites. Like MTX, CH-4051 has anti-inflammatory, autoimmune and anti-tumour properties and is a potent inhibitor of dihydrofolate reductase, an enzyme required for cell proliferation. The racemic mixture of CH-4051, known as CH-1405 (represented by the non-chiral structure in PubChem CID 9846537) [3], completed Phase 2 development for rheumatoid arthritis, and exhibited comparable efficacy to MTX [1-2]. Structurally, CH-4051 is the more active L-4'-methylene-glutamic acid containing diastereomer (or S-enantiomer) of CH-1405 [5].
