Novel agent #2714 potently inhibits lung cancer growth by suppressing cell proliferation and by inducing apoptosis in�vitro and in�vivo

This is the authors' abstract. We don't add key points for this paper.

The use of small molecule compounds to inhibit cell proliferation is one of the most promising approaches in cancer therapy. In the present study, a cell viability assay, flow cytometry analysis, western blotting and mouse xenograft models were used to investigate the anticancer activities of #2714 and its underlying mechanisms in lung cancer. The present in vitro results suggested that #2714 significantly inhibited the viability of the human non‑small cell lung cancer line SPC‑A1 in a concentration‑ and time‑dependent manner, with a half‑maximal inhibitory concentration value of 5.54 µM after 48 h of treatment. Additionally, #2714 inhibited SPC‑A1 cell proliferation via the Wnt/β‑catenin pathway and by impairing mitochondrial membrane potential. The protein expression levels of Wnt 3a, Wnt 5a/b, phosphorylated (p)‑β‑catenin, p‑glycogen synthase kinase 3β, and p‑mitogen‑activated protein kinase 14 were downregulated following treatment with #2714. Furthermore, using a mouse xenograft model, #2714 was identified to significantly inhibit tumor growth and to decrease cancer cell proliferation in vivo. #2714 may represent a novel effective anticancer compound targeting lung cancer cells. Additionally, #2714 was able to induce apoptosis and decrease cell proliferation in SPC‑A1 cells via the Wnt/β‑catenin pathway.
