Design, synthesis and pharmacological evaluation of 2-(thiazol-2-amino)-4-arylaminopyrimidines as potent anaplastic lymphoma kinase (ALK) inhibitors

Add time:07/15/2019    Source:sciencedirect.com

A series of new 2,4-diarylaminopyrimidine analogues (DAAPalogues) was developed by incorporation of a substituted 2-aminothiazole component as the C-2 substituent of the center pyrimidine core. Compound 5i showed highest potency of 12.4 nM against ALK and 24.1 nM against ALK gatekeeper mutation L1196M. Although only having moderate cellular potency in the SUP-M2 cells harboring NPM-ALK, compound 5i showed good kinase selectivity and dose-dependently inhibited phosphorylation of ALK and its down-stream signaling pathways.
