Biological Activity for Masitinib

Masitinib is a potent inhibitor of the tyrosine kinase receptor colony-stimulating factor 1R (CSF-1R) (IC₅₀ = 90 nM). It is also an NLRP3 inflammasome activator. Masitinib additionally inhibits the proteolytic activity of SARS-CoV-2 main protease (M^pro) and blocks viral replication, as well as acting as a PDGFRα/β inhibitor. In vivo, Masitinib ameliorates cognitive impairment in transgenic mice model of Alzheimer's disease, and slows disease progression in a rat model of amyotrophic lateral sclerosis (ALS). Orally bioavailable.
