lifirafenib

Lifirafenib (Beigene-283) is a potent inhibitor of RAF family kinases and EGFR in biochemical assays with IC50 of 23, 29 and 495 nM for the recombinant BRAFV600E kinase domain, EGFR and EGFR T790M/L858R mutant respectively.

Ticalopride is a 5-HT3 receptor agonist used in the treatment of digestive disorders, orofacial disorders, otorhinolaryngologic disorders, and may be used in the study of bulimia nervosa, gastroesophageal reflux, and irritable bowel syndrome.

Lifirafenib, also known as Beigene-283, is a Novel potent and selective RAF Kinase and EGFR inhibitor. BGB-283-displays Potent Antitumor Activity in B-RAF Mutated Colorectal Cancers. In vitro, BGB-283 potently inhibits B-RAFV600E-activated ERK phosphorylation and cell proliferation. It demonstrates selective cytotoxicity and preferentially inhibits proliferation of cancer cells harbouring B-RAFV600E and EGFR mutation/amplification. In B-RAFV600E CRC cell lines, BGB-283 effectively inhibits the reactivation of EGFR and EGFR-mediated cell proliferation. In vivo, BGB-283 treatment leads to dose-dependent tumor growth inhibition accompanied by partial and complete tumor regressions in both cell-line derived and primary human colorectal tumor xenografts bearing B-RAFV600E mutation. BGB-283 as a potent antitumor drug candidate with clinical potential for treating CRC harbouring B-RAFV600E mutation.

Lifirafenib (BGB-283) maleate, a novel inhibitor targeting both Raf Kinase and EGFR, exhibits potent activity with IC50 values of 23 nM and 29 nM against recombinant BRaf V600E and EGFR, respectively [1].
