FPHPB inhibits gastric tumor cell proliferation by inducing G2-M cell cycle arrest
2018
Abstract Gastric cancer is a common cancer in the world with high morbidity and mortality. Here, we report that FPHPB (4-(4-(2-fluoropyridin-3-yl)phenyl)- N -(4-hydroxyphenyl)), a derivative of CMPD-1/MK2a Inhibitor, had anti-tumor activities by inhibiting gastric tumor SNU-16 and SGC7901 cells. FPHPB dose-dependently inhibited cell proliferation, induced cell apoptosis and arrested SNU-16 and SGC7901 cells in G2-M cell cycle checkpoint. Upon treatment with FPHPB, apoptotic proteins cleaved PARP and cleaved caspase-3 were remarkably increased, and G2-M regulatory molecules, the phosphorylation of Cdc2 and Chk2, were significantly accentuated. Collectively, FPHPB has anti-tumor activities and may be a potential candidate for treating gastric cancers.
