ZX-29

ZX-29 is a potent and selective ALK inhibitor with an IC 50 of 2.1 nM, 1.3 nM and 3.9 nM for ALK , ALK L1196M and ALK G1202R mutations, respectively. ZX-29 is inactive against EGFR . ZX-29 induces apoptosis by inducing endoplasmic reticulum (ER) stress and overcomes cell resistance caused by an ALK mutation. ZX-29 also induces protective autophagy and has antitumor effect In Vitro ZX-29 (0-81 nM; 24-72 hours; NCI-H2228 cells) treatment leads to a time- and dose-dependent decrease in NCI-H2228 cell viability. ZX-29 (10 nM; 24 hours; NCI-H2228 cells) treatment causes typical signs of autophagy and the formation of autophagosomes. ZX-29 enhances the expression level of LC3 and Beclin1. ZX-29 (10 nM; 0-48 hours; NCI-H2228 cells) inhibits the proliferation of NCI-H2228 cells and arrests the cells in G1 phase. ZX-29 (10-40 nM; 24-48 hours; NCI-H2228 cells) treatment induces apoptosis of NCI-H2228 cells. ZX-29 dose-dependently upregulates the expression levels of proapoptotic protein Bax, increases the production of activated forms of caspase 3, and downregulates the expression level of antiapoptotic protein Bcl-2. ZX-29 (30-300 nM; 24 hours; NCI-H2228 cells) treatment significantly down-regulates the expression of p-ALK and its downstream signaling proteins, including p-Akt and p-STAT3, in a dose-dependent manner. ZX-29 (20 nM; 0-48 hours; NCI-H2228 cells) treatment significantly increases the mRNA level of CHOP. ZX-29 dose-dependently inhibits colony formation of NCI-H2228 cells. With an increase in ZX-29 concentration, the cell density decreased gradually, and the cells lost their normal morphology and become sharp and slender.
