Other natural compounds which have exhibited anti-cancer properties in breast cancer through modulation of STAT3 activity include: naringenin, ilamycin C, esculentoside A, catechol, dihydrotanshinone, DT-13, cucurbitacin E, galiellalactone, schisandrin A, pectolinarigenin, eupalinolide J, betulinic acid, deguelin, picrasidine G, and cantharidin (Table 1) (166–171, 173, 177, 180, 183, 185, 186, 190–192). This evidence concerns the gene STAT3 and cancer.
