Physical and Chemical Properties | Bioactive Selitrectinib (LOXO-195, BAY 2731954) is an orally active, highly effective, selective TRK kinase inhibitor with IC50 values of 2-9.8 nM for TRKA G595R, TRKC G623R and TRKA G667C. Its selectivity to targets is more than 1000 times that of non-TRK kinases detected by other 98%. |
Use | Introduction LOXO-195 is the next generation TRK kinase inhibitor. The IC50 of TRKA and TRKC is 0.6 nM and <2.5 nM respectively. |
In vitro study | LOXO-195 can effectively inhibit different activated TRK kinases in vitro. At a concentration of 1 μm, LOXO-195 was more than 98%-fold more selective for the target target than 228 of the other kinases tested (the pool contained 1000 kinases). In km2, CUTO-3 and O-91 cell lines containing TRK fusion, LOXO-195 can effectively inhibit the cell proliferation (IC50 <5 nmol/L). In the 84 cell lines that did not contain TRK fusions, LOXO-195 at concentrations up to 10 μm did not inhibit cell growth. |
In vivo study | In tumors driven by Δtrka, LOXO-195 effectively reduced phosphorylated TRKA levels. In four TRKA-dependent tumor models (a tumor model constructed by inoculating KM12 cells containing a fusion of NIH 3T3 Δtrka, Δtrka G595R, Δtrka G667C, and TPM3-NTRK1),LOXO-195 can cause tumor growth inhibition. |
