NUAK, the member of AMPK (AMP-activated protein kinase) family of protein kinases, is phosphorylated and activated by the LKB1 (liver kinase B1) tumor suppressor protein kinase. Recent work has indicated that NUAK1 is a key component of the antioxidant stress response pathway, and the inhibition of NUAK1 will suppress the growth and survival of colorectal tumors. As a promising target for anticancer drugs, few inhibitors of NUAK were developed. With this goal in mind, based on NUAK inhibitor WZ4003, a series of derivatives has been synthesized and evaluated for anticancer activity. Compound 9q, a derivative of WZ4003 by removing a methoxy group, was found to be the most potential one with stronger inhibitory against NUAK1/2 enzyme activity, tumor cell proliferation and inducing apoptosis of tumor cells. By in vivo efficacy evaluations of colorectal SW480 xenografts, 9q suppresses tumor growth more effectively with an excellent safety profile in vivo and is therefore seen as a suitable candidate for further investigation.

Aiming to develop novel Type-I1/2 inhibitors of ALK to overcome extensive resistance mutations, especially the L1196M mutation surrounding the ATP pocket, two series of 2-arylaminopyrimidine derivatives (11a-f and 22a-t) were designed based on scaffold hopping. The extensive structural elaboration discovered compound 22o which possessed excellent IC50 values of 0.06 and 0.23 μM against ALK-positive Karpas299 and H2228 cell lines, respectively. Meanwhile, 22o displayed encouraging inhibitory potency in the ALKWT (2.5 nM) and ALKL1196M (6.5 nM) enzymatic assays. Furthermore, the AO/EB and Hoechst 33258 assays illustrated 22o could induce cell apoptosis in a dose-dependent manner. Eventually, the molecular docking of 22o with ALK clearly presented the vital interactions within the active site, which was in accordance with Type-I1/2 inhibitor binding mode.
