Entrectinib (NMS-E628) is an orally active, BBB-penetrated and centrally active inhibitor of TrkA/B/C, ROS1 and ALK, with IC50 values of 1, 3, 5, 12 and 7 nM, respectively. Entrectinib induces apoptosis and cycle arrest in cancer cells, has antitumor activity, and attenuates bleomycin-induced lung fibrosis in mice.

Description
Entrectinib (NMS-E628) is an orally active, BBB-penetrated and centrally active inhibitor of TrkA/B/C, ROS1 and ALK, with IC50 values of 1, 3, 5, 12 and 7 nM, respectively. Entrectinib induces apoptosis and cycle arrest in cancer cells, has antitumor activity, and attenuates bleomycin-induced lung fibrosis in mice[1][2][3].
Entrectinib (100, 200, 400 nM; 24 h) alleviates TGF-β1-induced activation of mouse lung fibroblasts[1].
Entrectinib(100, 200, 400 nM; 24 h) inhibits TGF-β1-induced epithelial to mesenchymal transition of mouse lung epithelial cells[1].
Entrectinib (10, 50, 250 nM; 2 h) abolishes autophosphorylation of TPM3-TRKA, concomitant with complete inhibition of the phosphorylation of PLCg1, AKT, and MAPK in KM12 cells[2].
Entrectinib (10, 50, 250 nM; 24, 48 h) induce KM12 cells cycle arrest (24 h) and apoptosis (48 h)[2].

*Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles. Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day. The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
