Cis-9,10-Octadecenoamide
Also known as oleamide. A naturally-occurring derivative of oleic acid (a monounsaturated fatty acid) that induces sleep. Research is ongoing, but in-vitro and rodent experiments indicate it may have other functions as well. For example, it may have anxiolytic (anxiety-reducing) and anti-convulsant activities. Oleamide derivatives also inhibit the metastasis of cancer cells in-vitro.
