Pinitol is a cyclitol, a cyclic polyol. It is a known anti-diabetic agent isolated from Sutherlandia frutescens leaves. Gall plant tannins can be differentiated by their content of pinitol. It was first identified in the sugar pine (Pinus lambertiana). Certain variants of the bacteria Pseudomonas putida have been used in organic synthesis, the first example being the oxidation of benzene, employed by Steven Ley in the synthesis of (+/-)pinitol. Breast cancer is the most prevalent malignant neoplasm in the world, and chemoprevention through dietary intervention strategy is an emerging option to reduce the incidence. D-pinitol (DP), a major component of soya bean, possesses attractive biological actions. We have investigated whether D-pinitol have an effect on tumor growth in vivo against 7,12-dimethylbenz(a)anthracene (DMBA)-initiated rat mammary carcinogenesis and investigated its mechanism of action.
