(-)-Hinesol (Hinesol) is a potent anticancer agent. (-)-Hinesol induces apoptosis and cell cycle arrest at G0/G1 phase. (-)-Hinesol downregulates MEK/ERK pathway and NF-κB pathway and mediates theexpression of cyclin D1, Bax and Bcl-2. (-)-Hinesol has the potential for the research of non–small cell lung cancer.
