There are some other compounds that induce cancer cell death or an anti-proliferative effect, such as artonin E (22) [72], myricetin (23) [73], xanthones (24) [138], cycloartobiloxanthone (25) [139], paratocarpin E (26) [74], and puerarin 6′’-O-xyloside (27) by regulating the Bcl-2 family proteins [75]. Here, BCL2 is linked to cancer.
