Aiming to identify novel potent ALK and ROS1 dual inhibitors, the relatively bulky piperidine fragment in ceritinib was replaced with substituted imidazolidin-2-one moiety which gave rise to a series of 2,4-diaryl-aminopyrimidine (DAAP) analogs (6–33). SAR studies were conducted based on cellular assays on five cell lines and most compounds exerted moderated to excellent activities. Among them, 15 showed excellent inhibitory activities against ROS1 and ALK positive cell lines, especially Ba/F3G1202R, with IC50 values ranging from 14 to 37 nM. As a continuation, several compounds were tested in enzymatic assays and 15 displayed encouraging activities against wild-type ALK (1.2 nM), ROS1(0.43 nM) as well as extremely resistant ALKL1196M and ALKG1202R mutants with IC50 values of 0.73 nM and 6.7 nM, respectively. To our delight, both cellular and enzymatic results of 15 were in good accordance with western blot assays on H2228 and HCC78 cell lines. Importantly, pharmacokinetic (PK) profiles of 15 were obtained with quite satisfying AUC and Cmax values. Besides, the binding models of 15 with ALKWT, ALKG1202R and ROS1 clearly present the essential interactions within the active site.

In order to explore novel ALK and ROS1 dual inhibitors capable of overcoming crizotinib-resistant mutants, two series of 2,4-diarylaminopyrimidine derivatives were designed, synthesized and evaluated for their in vitro cytotoxic activity. In this work, we retained the 2,4-diarylaminopyrimidine scaffold and derivatize the DAAP scaffold with sulfonyl and acrylamide moieties to extend the structure–activity relationship (SAR) study. To our delight, some compounds exhibited excellent inhibitory activity with a double-digit nanomolar level in MTT assay. Four compounds were selected for enzymic assays further, the results led to the identification of a potent ALK and ROS1 dual inhibitor X-17, with IC50 values of 3.7 nM, 2.3 nM, 8.9 nM and 1.9 nM against ALK, ALKL1196M, ALKG1202R and ROS1, respectively. Ultimately, the molecular docking studies on X-17 clearly disclosed reasonable and optimal binding interactions with ALK.
