Tagarafdeg
Based on 1 publication(s) in Google Scholar
Tagarafdeg (CFT1946) is an orally active, blood-brain barrier-penetrant, and selective bifunctional BiDAC degrader of the BRAFV600E/K mutant protein, with a DC50 of 14 nM in A375 cells. Tagarafdeg mediates the ubiquitination and proteasomal degradation of BRAF mutant proteins. Tagarafdeg inhibits tumor progression in multiple models of BRAFV600E-mutant intracranial tumors, melanoma, and colorectal cancer. Tagarafdeg is applicable to tumor-related research.

[1]|
BRafV600E 14 nM (DC50) |
In Vitro
Tagarafdeg (CFT1946) (1-10000 nM; 24 h) degrades BRAFV600E protein and downregulates pERK protein levels in a dose-dependent manner in A375 cells (DC50 = 14 nM, Emax = 26%); it does not degrade wild-type BRAF protein in HCT116 cells harboring wild-type BRAF, and exerts almost no effect on the MAPK signaling pathway and cell proliferation[1].
Tagarafdeg inhibits the proliferation of BRAF inhibitor-resistant A375‑NRAS Q61K cells (GI50 = 150 nM); it exhibits weak antiproliferative activity against HepG2 cells (GI50 >10 μM)[1].
Tagarafdeg (100 nM; 24 h) induces the degradation of BRAFV600E and inhibits MAPK signal transduction, resulting in the loss of pERK in BRAFV600E cells, but exerts no effect in WTV600E cells[1].

-
Concentration:100 nM
co‑treatment with 10 μM competing ligand (targeting ligand / CRBN ligand / MLN4924 (HY-70062) / Bortezomib (HY-10227)) -
Incubation Time:24 h
-
Result:Abolished CFT1946‑mediated BRAF‑V600E degradation via target‑ligand competition, CRBN‑ligand competition, CUL4‑E3 inhibition and proteasome inhibition.
-
Cell Line:A375 cells
-
Concentration:1, 10, 100, 1000, 10000 nM
-
Incubation Time:24 h
-
Result:Induced dose‑dependent BRAF‑V600E degradation and reduced pERK levels; the CRBN‑binding‑deficient analogue CFT1946NMe failed to degrade BRAF‑V600E.
-
Cell Line:HCT116 cells
-
Concentration:1, 10, 100, 1000, 10000 nM
-
Incubation Time:24 h
-
Result:Exerted no obvious alterations on protein abundance of WT‑BRAF, pERK and total‑ERK.
In Vivo
Tagarafdeg (10-30 mg/kg; oral administration, twice daily) inhibits tumor growth in BRAF inhibitor-resistant A375-NRAS Q61K xenograft mice, and its combination with the MEK inhibitor Trametinib (HY-10999) yields an enhanced antitumor effect[1].
