CST905
CST905 is a potent BRAF-V600E PROTAC degrader with a DC50 of 18 nM. CST905 recruits the VHL E3 ligase to form a ternary complex, mediating the degradation of BRAF-V600E via the ubiquitin-proteasome pathway. The ligand of CST905 disrupts the RAF dimerization interface, thereby preventing the aberrant activation of the harmful MAPK/ERK pathway in RAS-mutated cells while degrading the target protein. CST905 can be used in studies related to malignant melanoma and neuroblastoma.

In Vitro
CST905 (0.1-10 μM; 4-24 h) exerts effects of degrading BRAF-V600E protein (IC50 = 18 nM) and inhibiting ERK1/2 phosphorylation (IC50 = 31 nM) in human malignant melanoma SK-MEL-28 cells[1].
CST905 (up to 10 μM; 120 h) exerts inhibitory effects on cell proliferation and reduces cell viability in human malignant melanoma SK-MEL-28 cells (GI50 = 61 nM)[1].
CST905 (0.1-10 μM; 4-24 h) does not induce abnormal activation of p-ERK1/2 or p-MEK1/2, nor does it affect the expression of wild-type BRAF protein or the level of p-ERK1/2 in human neuroblastoma SK-N-AS cells[1].

Cell Line:SK-MEL-28 cell line and SK-N-AS cell line
-
Concentration:0.1, 1, 10 μM
-
Incubation Time:4 h
-
Result:Decreased the intracellular expression level of the mutant target protein and effectively down-regulated the phosphorylation activation of downstream signaling molecules.
Did not cause paradoxical hyperphosphorylation and activation of downstream key kinase signals in the mutant cells, avoiding undesirable paradoxical activation.
