TRK-IN-34
TRK-IN-34 is an orally active TRKand TRKC mutant kinase inhibitor, with IC50 values of 0.75 nM and 0.96 nM against TRKAG595R and TRKAG667C, respectively. TRK-IN-34 inhibits the kinase activities of TRKAG595R and TRKAG667C at the functional level. TRK-IN-34 inhibits the proliferation of TRKA-transfected cells, exerts tumor growth-inhibitory effects and achieves partial tumor regression in xenograft models. TRK-IN-34 can be used to study TRK inhibitor-resistant cancers driven by the TRKAG667C mutation.

TRK-IN-34 (compound 5c) shows satisfactory metabolic stability in human liver microsomes with a long half-life of 153.1 min[1].
TRK-IN-34 (3 days) potently inhibits the proliferation of Ba/F3 cells expressing wild-type or mutant TRKA fusion proteins. Its IC50 values against CD74-NTRK1-WT, CD74-NTRK1-G595R, and CD74-NTRK1-G667C are 3 nM, 6 nM, and 17 nM, respectively[1].
TRK-IN-34 (1.23-300 nM; 6 h) dose-dependently inhibits the phosphorylation of TRKA and its downstream signaling proteins PLCγ1 and ERK in Ba/F3 cells expressing wild-type or mutant TRKA fusion proteins after 6 h of treatment[1].
TRK-IN-34 potently inhibits wild-type and mutant TRK kinases in a cell-free enzymatic assay. The IC50 values for key drug-resistant mutants such as TRKAG595R, TRKAG667C, TRKCG623R and TRKAF589L are 0.75 nM, 0.96 nM, 0.73 nM and 0.44 nM, respectively[1].
