Discovery of N -(5-((5-chloro-4-((2-(isopropylsulfonyl)phenyl)amino)pyrimidin-2-yl)amino)-4-methoxy-2-(4-methyl-1,4-diazepan-1-yl)phenyl)acrylamide (CHMFL-ALK/EGFR-050) as a potent ALK/EGFR dual kinase inhibitor capable of overcoming a variety of ALK/EGFR associated drug resistant mutants in NSCLC
摘要:
Recently, more and more concomitant EGFR mutations and ALK rearrangement are observed from the clinic, which still lacks effective single-agent therapy, Starting from ALK inhibitor 14 (TAE684), we have developed a highly potent EGFR/ALK dual kinase inhibitor compound 18 (CHMFL-ALK/EGFR-050), which potently inhibited EGFR L858R, del 19 and T790M mutants as well as EML4-ALK, R1275Q L1196M, F1174L and C1156Y mutants biochemically. Compound 18 significantly inhibited the proliferation of EGFR mutant and EML4-ALK driven NSCLC cell lines. In the cellular context it strongly affected EGFR and ALK mediated signaling pathways, induced apoptosis and arrested cell cycle at G0/G1 phase. In the in vivo studies, 18 significantly suppressed the tumor growth in H1975 cell inoculated xenograft model (40 mg/kg/d, TGI: 99%) and H3122 cell inoculated xenograft model (40 mg/kg/d, TGI: 78%). Compound 18 might be a potential drug candidate for EGFR- or ALK-individual as well as concomitant EGFR/ALK NSCLC. (C) 2017 Elsevier Masson SAS. All rights reserved.
The present application provides a compound of formula I, which is a EGFR and ALK dual inhibitor and can be used alone or in combination with other therapeutic agents to treat diseases such as non-small cell lung cancer. The compounds of the present application are useful in the treatment of diseases carrying the EGFR wild-type gene, or carrying the EGFR T790M mutant gene and/or the EGFR L858R mutant gene and/or the EGFR delE746_A750 mutant gene, or in the treatment of diseases carrying the ALK wild-type gene, ALK F1174L mutant gene and/or ALK F1196M gene and/or EML4-ALK mutant gene and/or NPM-ALK mutant gene, and can be used in the first-line treatment of anaplastic lymphoma kinase (ALK) positive late-stage non-small cell Lung cancer.
