RAF mutant-IN-1 is an inhibitor of RAF kinase(IC50 values of 21 nM, 30 nM and 392 nM for C-RAF 340D Y341D, B-RAFV600E and B-RAFWT, respectively).

B-Raf IN 11 is a novel selective inhibitor. The DFG-in conformation of the B-Raf kinase V600E mutant is superior to the DFG-out conformation in colorectal cancer.

SJ-C1044 is an orally effective pan-RAF inhibitor demonstrating immunomodulatory and antitumor activities. It targets wild-type BRAF, wild-type CRAF, and BRAF(V600E) with IC50 values of 331, 257, and 187 nM, respectively. SJ-C1044 suppresses tumor cell proliferation by inhibiting kras activation and MEK-ERK phosphorylation. Additionally, it shows inhibition of VEGFR2, TIE2, and CSF1R, with IC50 values of 100, 23, and 235 nM respectively. The compound enhances the tumor immune microenvironment through inhibition of angiogenesis and modulation of macrophage function. SJ-C1044 is applicable for research in colorectal cancer.

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.

RAF-IN-1 is a potent inhibitor of b cRAF, acting on cRAF (IC50: 3.8 nM), bRAFwt (IC50: 36 nM), and bRAFV600E (IC50: 29.4 nM), and inhibiting A375 and H358 cell lines carrying the bRAFV600E mutation with a GI50 of 3.4 and 2.9 nM, respectively.

SHR902275 is a selective, potent, orally active RAF inhibitor targeting RAS mutant cancers, acting on cRAF (IC50: 1.6 nM), bRAFwt (IC50: 10 nM), and bRAFV600E (IC50: 5.7 nM). SHR902275 exhibits cell growth inhibitory effects in H358 cells (GI50: 1.5 nM), A375 cells (GI50: 0.17 nM), Calu6 cells (GI50: 0.4 nM), and SK-MEL2 cells (GI50: 0.32 nM).

VEGFR-2 BRAF-IN-1, a dual inhibitor of VEGFR-2 and BRAF kinases, demonstrates potent inhibitory activity with IC50 values of 0.049 µM for VEGFR-2, 0.063 µM for BRAF V600E, and 0.005 µM for BRAF WT. It effectively induces apoptosis and arrests the cell cycle primarily at the G1 S phase.

VEGFR-2 BRAF-IN-2, as a dual VEGFR-2 and BRAF kinase inhibitor, exhibits potent IC50 values of 0.111 µM, 0.089 µM, and 0.071 µM against VEGFR-2, BRAF V600E, and BRAF WT, respectively. This compound effectively induces apoptosis and predominantly arrests the cell cycle in the G1 phase.

MAPK-IN-2 (compound 3h) is an efficacious MAPK inhibitor with antineoplastic properties that significantly hinders proliferation across various cancer cell lines. It demonstrates robust suppression of the MAPK pathway (EGFR WT IC50 = 281 nM, c-MET IC50 = 205 nM, B-RAF WT IC50 = 112 nM, CDK4 6 IC50 = 95 and 184 nM, respectively) and exhibits pronounced activity against mutated forms of EGFR and B-RAF (EGFR T790M IC50 = 69 nM and B-RAF V600E IC50 = 83 nM) [1].
