DZX19
DZX19 (Compound C02) is an orally active, selective TRK inhibitor with a TRKA IC50 value of 1.32 nM, a TRKB IC50 of 2.28 nM, and a TRKC IC50 of 4.05 nM. DZX19 inhibits the kinase activities of wild-type TRKA, TRKA mutants (G595R, F589L, G667C), wild-type TRKB, and wild-type TRKC, and suppresses the phosphorylation of TRKA as well as its downstream AKT and ERK signaling pathways. DZX19 induces apoptosis. DZX19 inhibits tumor growth in a colorectal cancer xenograft mouse model. DZX19 is applicable for the research of colorectal cancer.

DZX19 (C02) (72 h) potently inhibits the proliferation of TRK fusion-positive and TRKA mutant-harboring cell lines, with greater efficacy than Entrectinib, and exhibits minimal off-target activity in TRK-negative A549 cells[1].
DZX19 (C02) (7.5-15 nM; 14 days) strongly suppresses the long-term colony-forming ability of TRK fusion-positive Km-12 cells more effectively than Entrectinib[1].
DZX19 (C02) (7.5-15 nM; 48 h) potently inhibits the migration of TRK fusion-positive Km-12 cells more effectively than Entrectinib[1].
DZX19 (C02) (7.5-30 nM; 24 h) dose-dependently induces G1 cell cycle arrest in TRK fusion-positive Km-12 cells, with stronger activity than Entrectinib[1].
