Crizotinib (PF-02341066)Crizotinib (PF-02341066) is a potent inhibitor of c-Met and ALK with IC50 of 11 nM and 24 nM in cell-based assays, respectively. It is also a potent ROS1 inhibitor with Ki value less than 0.025 nM. Crizotinib induces autophagy through inhibition of the STAT3 pathway in multiple lung cancer cell lines. |
(c) Western blot analyses of p-Akt (Ser473) and p-S6RP (Ser235 and Ser236) in two RCT-E565 transplanted tumors treated with vehicle or PF02341066. Samples were isolated 4 h after the last dose from mice treated with PF02341066 for 3 d. (d) Responses of RCT-E565 transplanted tumors in athymic mice to PF02341066 or vehicle. Data are means ±s.e.m. (each group, n = 6). *P < 0.005, **P < 0.001 (Student,s t test). |

Merestinib (LY2801653)Merestinib (LY2801653) is a type-II ATP competitive, slow-off inhibitor of MET tyrosine kinase with a dissociation constant (Ki) of 2 nM, a pharmacodynamic residence time (Koff) of 0.00132 min(-1) and t1/2 of 525 min. Merestinib (LY2801653) also inhibits MST1R, AXL, ROS1, MKNK1/2, FLT3, MERTK, DDR1 and DDR2 with IC50 of 11 nM, 2 nM, 23 nM, 7 nM, 7 nM, 10 nM, 0.1 nM and 7 nM, respectively. |

Entrectinib (RXDX-101)Entrectinib (RXDX-101, NMS-E628) is an orally bioavailable pan-TrkA/B/C, ROS1 and ALK inhibitor with IC50 ranging between 0.1 and 1.7 nM. Entrectinib (RXDX-101) induces autophagy. Phase 2. |
Tumor cells were treated with entrectinib (10 nmol/L) for 4 hours or c-PARP for 48 hours, and harvested lysates were assessed by Western blotting. Data shown are representative of three independent experiments with similar results.

Brigatinib (AP26113)Brigatinib (AP26113) is a potent and selective ALK (IC50, 0.6 nM) and ROS1 (IC50, 0.9 nM) inhibitor. It also inhibits IGF-1R, FLT3, and mutant variants of FLT3 (D835Y) and EGFR with lower potentcy. |
Immunoblotting analysis of H3122 and H3122-CER cells showing that brigatinib did not inhibit EGFR phosphorylation (p-EGFR). Total EGFR (t-EGFR) is also shown. Actin was used as a loading control. The cells were treated with brigatinib for 2 hours.
