We are continously working on projects and one of our aims is to investigate if the polyacetylenes Falcarinol and Falcarindiol from selected carrot cultivars prevent neoplastic transformation and growth in humans, with the benefit of having no side effects. The selective COX-2 inhibitory effect and the antineoplastic effect has been described in both human cancer cell lines and in rats primed to develop bowel cancer. We hope that we can individualise the treatment of patients with high-risk polyps in the colon.
