CG428
Based on 1 Customer Validation
CG428 is a potent and selective CRBN-dependent tropomyosin receptor kinase (TRK) PROTAC degrader that has anti-tumor activity. CG428 reduces levels of the tropomyosin 3 TPM3-TRKA fusion protein in KM12 colorectal carcinoma cells (DC50 = 0.36 nM) and inhibits downstream PLCγ1 phosphorylation (IC50 = 0.33 nM). CG428 has a higher binding affinity for TRKA than TRKB and TRKC (Kd = 1 nM, 28 nM and 4.2 nM, respectively). CG428 can be used for the research of colorectal carcinoma.
(Pink: Trk Receptor ligand (HY-118271); Blue: Cereblon ligand (HY-41547); Black: linker (HY-W067489)).

CG428 binds with high affinity to recombinant TRKA, TRKB, and TRKC kinases, with Kd values of 1.0, 28.0 and 4.2 nM[1].
CG428 degrades endogenous TPM3-TRKA fusion protein (DC50 = 0.36 nM) and inhibits PLCγ1 phosphorylation (IC50 = 0.33 nM) in KM12 cells[1].
CG428 potently degrades endogenous wild-type TRKA in HEL cells with a DC50 of 2.23 nM[1].
CG428 (0.7-500 nM; 6 h) exhibits reduced potency for degradation of ectopically expressed AGBL4-TRKB and ETV6-TRKC fusion protein in KM12 cells, with a hook effect at high concentrations[1].
CG428 potently inhibits the growth of KM12 cells with an IC50 of 2.9 nM[1].
