Anatabine (uh-nat-uh-been,-bin) is one of the minor alkaloids found in plants in the Solanaceae family, which includes the tobacco plant and tomato. Commercial tobacco plants typically produce alkaloids at levels between 2% and 4% of total dry weight, with nicotine accounting for about 90% of the total alkaloid content, and the related compounds anabatine, nornicotine, and anabasine making up nearly all the rest. These compounds are thought to be biologically active, and part of plants' natural defense system against insects.
Anatabine has been studied in animal models and in cells to see if it might be useful for treating nicotine addiction and inflammation, and has been studied in models of diseases characterized by inflammation, such as Alzheimer's Disease, thyroiditis, and multiple sclerosis. On a biochemical level, it appears to be active against certain nicotinic acetylcholine receptors.
