In this study, a series of novel 2,4-diaminopyrimidines bearing fused tricyclic ring moiety was described for ALK inhibitor. The pyrazole, imidazole, 1,2,4-triazole, piperazine and phenanthridine moieties were employed at the 2-position of pyrimidine. Among the compounds synthesized, 28, 29, 36, and 42 showed promising anti-ALK activities in enzymatic- and cell-based assays. In vivo H3122 xenograft model study showed that compound 29 effectively suppressed ALK-driven tumor growth, similar to the extent of ceritinib, suggesting that it could be used for a novel ALK inhibitor development.
