Entrectinib (NMS-E628、RXDX-101、NMS-01191372) 是一种有效的、ATP 竞争性、口服的泛 TRK、ROS1 和 ALK 抑制剂，对于 TRKA/TRKB/ 的 IC50 为 1/3/5/12/7 nM分别为 TRKC/ALK/ROS1。

Entrectinib (NMS-E628, RXDX-101, NMS-01191372) is a potent, ATP-competitive, orally available pan-TRK, ROS1 and ALK inhibitor with IC50 of 1/3/5/12/7 nM for TRKA/TRKB/TRKC/ALK/ROS1, respectively; exhibits high antiproliferative activity against colorectal carcinoma cell line KM12 with IC50 of 17 nM, abolishes autophosphorylation of TPM3-TRKA, concomitant with complete inhibition of the phosphorylation of PLCγ1, AKT, and MAPK; induces regression in relevant human xenograft tumors, including the TRKA-dependent colorectal carcinoma KM12, ROS1-driven tumors, and several ALK-dependent models.Lung Cancer Phase 2 Clinical(In Vitro):Entrectinib (NMS-E628) is found to be exquisitely active in inhibiting the proliferation of a limited number of cell lines: the TRKA-driven colorectal carcinoma cell line KM12 (IC50 of 17 nM), the ALK-dependent ALCL cell lines SU-DHL-1, Karpas-299, SUP-M2 and SR-786 (IC50 of 20, 31, 41, and 81 nM, respectively), the ALK-dependent NSCLC cell line NCI-H2228 (IC50 of 68 nM) and the FLT3-dependent AML cell line MV-4-11 (IC50 of 81 nM). Entrectinib potently blocks proliferation of Ba/F3-TEL-TRKB (IC50 of 2.9 nM), Ba/F3-TEL-TRKC (IC50 of 3.3 nM), and Ba/F3-TEL-ROS1 (IC50 of 5.3 nM) cells, with a high degree of selectivity versus parental Ba/F3 cells or those transformed by nontargeted kinases such as ABL and RET, which are inhibited with IC50s in the range of 2 to 3 μM. Entrectinib significantly inhibits the growth of TrkB-expressing NB cells in vitro, and it significantly enhances the growth inhibition of Irino-TMZ when used in combination.(In Vivo):Oral administration of entrectinib to tumor-bearing mice induces regression in relevant human xenograft tumors, including the TRKA-dependent colorectal carcinoma KM12, ROS1-driven tumors, and several ALK-dependent models of different tissue origins, including a model of brain-localized lung cancer metastasis. Single agent therapy results in significant tumor growth inhibition in animals treated with entrectinib compared to control animals.
