Isothiocyanates, which are the bioactive components in broccoli and other cruciferous vegetables, have been shown to suppress COX-2 and IL-6 production from inflammation. The polyacetylene gymnasterkoreayne B (GKB) was previously shown to increase detoxification enzymes, but has not previously been tested for anti-cancer activity (1). Here we tested 10% broccoli, 5% broccoli sprouts, GKB and a GKB-rich extract from Gymnaster koriensis (GE) for their ability to prevent inflammation-enhanced colon cancer, using the dextran sulfate sodium/ azoxymethane mouse model. GKB (500 µmol/kg diet daily), GE (providing an equal dose of GKB) and broccoli protected against some aspects of inflammation, including cyclooxygenase-2 levels in colonic mucosa. The extract and the 10% broccoli diet, but not purified GKB or 5% broccoli sprouts, protected against colon cancer, decreasing adenocarcinomas by 90%.
