β-lap also shows anti-cancer activity against a number of human breast and prostate cancer cell lines [37], [38], [39]by selectively inducing NQO1-dependent apoptosis, as well as inducing NQO1-independent apoptosis in the HepG2 hepatoma cell line through the induction of Bax and the activation of caspases [40]. Here, NQO1 is linked to cancer.
