Description:

WARNING: This product is for research use only, not for human or veterinary use.

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.

Safety Data Sheet (SDS)
Biological target:
Lifirafenib (BGB-283) is a novel and potent Raf Kinase and EGFR inhibitor with IC50 values of 23 and 29 nM for recombinant BRafV600E and EGFR, respectively.
In vitro activity:
BGB‐283 and compound C inhibited vemurafenib‐induced ERK phosphorylation with an IC50 of 1.2 µm and 84.1 nm. All these findings demonstrate that BGB‐283 and compound C, unlike vemurafenib, inhibit RAF dimer in K‐RAS‐mutated cancer cells and in melanoma cells expressing the p61‐B‐RAFV600E dimer. Reference: Mol Oncol. 2020 Aug;14(8):1833-1849. https://pubmed.ncbi.nlm.nih.gov/32336014/
In vivo activity:
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 BRAF(V600E) mutation. These findings support BGB-283 as a potent antitumor drug candidate with clinical potential for treating colorectal cancer harboring BRAF(V600E) mutation.
