ALK-IN-12 is a highly potent and orally active inhibitor of anaplastic lymphoma kinase (ALK), demonstrating an exceptional IC50 value of 0.18 nM. Additionally, ALK-IN-12 displays inhibitory activity against insulin-like growth factor 1 receptor (IGF1R) and insulin receptor (InsR), with IC50 values of 20.3 nM and 90.6 nM, respectively. Notably, its antitumor effects have been observed, making it a promising compound for targeted cancer therapy.
ALK-IN-9 (compound 40) is a highly effective ALKinhibitor. It demonstrates remarkable inhibitory activity against cell proliferation, with IC50 values of <0.2 nM for Ba F3-EML4-ALK, KM 12 (TPM3-TRKA), and KG-l cell (OP2-FGFR1).
Trk-IN-7 (compound I-6) is a highly potent inhibitor of TRK, exhibiting IC50 values ranging from 0.25-10 nM for TRKA, TRKB, and TRKC, respectively. In addition, Trk-IN-7 demonstrates notable inhibition against EML4-ALK (IC50 <15 nM), as well as ALK G1202R, ALK C1156Y, ALK R1275Q, ALK F1174L, ALK L1197M, and ALK G1269A (IC50 = 5-50 nM) [1].
Trk-IN-10 (Compound 14j) is a highly effective inhibitor of TRK, with an IC50 of 0.86 nM against TrkA and 6.92 nM against TrkA G595R. As an RTK, Trk plays a crucial role as a drug target in solid tumors. Trk-IN-10 (IC50 = 350 nM against ALK) demonstrates superior selectivity ininhibiting Trk, which has potential implications for toxicity reduction [1].
PF-06463922 acetate is a potent, selective brain-penetrable inhibitor of both anaplastic lymphoma kinase (ALK) and c-ros Oncogene 1 (ROS1) with strong activity against all known ALK and ROS1 mutants identified in patients with crizotinib-resistant disease. PF-06463922 is in clinical trials for the treatment of non–small cell lung cancer (NSCLC).
