PF-06463922 is a potent and selective ALK/ROS1 inhibitor with IC50 values ranging from 0.19-0.53 nM for the kinase activity of ROS1 fusion enzymes [1].
The receptor tyrosine kinase c-ros oncogene1 (ROS1) is a receptor with a kinase domain that is related to the anaplastic lymphoma kinase/lymphocyte-specific protein tyrosine kinase (ALK/LTK) and insulin receptor (INSR) RTK families [1].
Via cellular ROS1 autophosphorylation in the recombinant enzyme assay, PF-06463922 showed a 30-fold improved potency against ROS1, compared with crizotinib, ceritinib, alectinib and foretinib (XL-880). Engineered NIH 3T3 cells were expressing oncogenic human ROS1 fusions. In these cells, PF-06463922 was more potent than foretinib and crizotinib by >10 folds, more potent than alectinib and ceritinib by >100 folds against cellular ROS1 autophosphorylation [1].
Oncogenic gene fusions involving the 3' region of ROS1 kinase had been found in various human cancers [2]. Mice bearing CD74-ROS1, CD74-ROS1G2032R and FIG-ROS1(S) s.c. Tumors (250 mm3) were used. Treatments with PF-06463992 at various doses were applied consecutively for 7 or 9 d. At dosages of 0.2 to 1 mg/kg/d, PF-06463922 significantly inhibited the growth of both established FIGROS1(S) and CD74-ROS1 tumors compared with vehicle control. At 2-6 mg/kg/d, PF-06463922 significantly made tumor volumes regress (58–85%, P < 0.0001). In animals bearing NIH 3T3-CD74-ROS1G2032R tumors, treatment with PF-06463922 at 1.0, 3.0, and 10 mg/kg/d significantly inhibited tumor growth by 28%, 44% and 90%, respectively. At 30 mg/kg/d, PF-06463922 made tumor regress by 12%, compared with vehicle [1].

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
