Deguelin is a derivative of rotenone. Both are compounds classified as rotenoids of the flavonoid family and are naturally occurring insecticides. They can be produced by extraction from several plant species belonging to three genera of the Fabaceae or Legume family, Lonchocarpus, Derris, or Tephrosia.
Contents
Cubé resin, the root extract from Cubé (Lonchocarpus utilis) and from Barbasco (Lonchocarpus urucu), is used as a commercial insecticide and piscicide (fish poison). The major active ingredients are rotenone and deguelin. Although "organic" (produced by nature) cubé resin is no longer considered environmentally safe.
Pharmacokinetics
Deguelin and anti-cancer activity
Deguelin displays anti-cancer activity by inhibiting the growth of pre-cancerous and cancerous cells - particularly for lung cancer. So far the compound has shown no toxic effects on normal cells. However, high doses of deguelin are suspected of having negative effects on the heart, lungs and nerves. The molecular mechanisms include the induction of apoptosis, mediatated through AKT/PKB signaling pathways in malignant and premaligant human bronchial epithelia (HBE) cells, with only minimal effects on normal HBE cells. Deguelin inhibits AKT by both Phosphoinositol-3-phosphate kinase (PI3K)-dependent and PI3K-independent pathways.
Deguelin and Parkinson's disease
Research has shown a correlation between intravenous deguelin and Parkinson's disease in rats. The study does not suggest that deguelin exposure is responsible for Parkinson's disease in humans, but is consistent with the belief that chronic exposure to environmental toxins can increase the likelihood of the disease.
