Dietary intake of pyrolyzed deketene curcumin inhibits gastric carcinogenesis

Abstract

Gastric cancer is the second leading cause of cancer-related mortality worldwide. Curcumin, a phytochemical, possesses molecular inhibitory potentials for regulating malignancies. However, the lower potential of curcumin warrants improvement. Thus, we synthesized diarylpentanoid analogs with higher potency; however, these differed structurally from curcumin—a heptanoid. Recently, one diarylpentanoid was formed following pyrolysis of curcumin, which is identical to our GO-Y022. The growth inhibition of gastric cancer cells by GO-Y022 was five-fold higher than by curcumin; GO-Y022 displayed superior apoptosis induction ability. Besides, it suppressed the gastric tumor growth to a third in a mouse model. GO-Y022 was moved to the epithelial and gastric tumors but not detected in the bloodstream. Moreover, oral GO-Y022 was effective topically, exhibited no adverse events in mice, and was detected in the commercially available curry paste. Briefly, GO-Y022 can inhibit gastric carcinogenesis; it is dietary and can be safely used as an oral functional food.
