Description

Oleoyl-estrone (OE) is a fatty acid ester of estrone. This hormone occurs naturally and is found circulating in various animal species and humans. It has been shown in animal studies to promote the loss of body fat while maintaining body protein storage, maintaining nitrogen balance. Body protein loss is an unpleasant effect of fat loss by the restriction of calories, and studies show that this drug appears to avoid this effect.

Pharmacodynamics

Oleoyl-estrone is a fatty acid ester of estrone, and may be directly involved in the control of body weight (PMID: 8782737).

Mechanism of action

Based on extensive preclinical studies, it is believed that oleoyl-estrone (OE) works by a dual mechanism of action. Centrally, OE appears to act at the brain's hypothalamus, resetting the body's ponderostat, the “food control center” in the brain that detects and integrates signals that control both appetite and metabolic behavior. Peripherally, OE also causes reduced storage of fat in “white fat” tissue and allows skeletal muscle to use fat as an alternate energy source.
