Trk Receptor Degrader

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.

PROTAC NTRK1 degrader-1 is a wild-type and mutant NTRK1 PROTAC degrader with IC₅₀ values of 4 nM (wild-type), 2 nM (G595R), 5 nM (G667C), and <0.5 nM (F598L). PROTAC NTRK1 degrader-1 catalyzes ubiquitination and subsequent proteasome-mediated degradation of wild-type and mutant (G595R, G667C, F598L) NTRK1. PROTAC NTRK1 degrader-1 can be used for the research of solid tumors.

JWJ-01-378 is a selective TRK PROTAC degrader. JWJ-01-378 efficiently degrades WT TRK and TPM3-TRKA fusion proteins and inhibits downstream pERK signaling, while showing limited efficacy against TRK inhibitor resistant mutants and ALK fusions. JWJ-01-378 potently suppresses cancer cell proliferation.Pink: TRK ligand (HY-160520); Blue: CRBN ligase ligand (HY-103596); Black: linker

ZW-18-116 (compound 9) is a dual-target PROTAC degrader for the oncoproteins TRKA and RET. ZW-18-116 induces the degradation of oncoproteins TRKA and RET by recruiting the CRBN E3 ligase. ZW-18-116 exhibits potent anti-proliferative activity in various cancer cell lines harboring RET or TRKA fusions. ZW-18-116 can be used for RET or TRKA-derived cancer research, such as thyroid, lung, and colon cancers.

ZW-6-052 (compound 20), the derivative of ZW-18-116 (HY-180550), is a dual-target PROTAC degrader for the oncoproteins TRKA and RET. ZW-6-052 induces degradation of TMP3-TRKA in KM12 mouse xenograft models. ZW-6-052 can be used for RET or TRKA-derived cancer research, such as thyroid, lung, and colon cancers.
