Common NameLeptosine
DescriptionLeptosine, also known as leptosin j, is a member of the class of compounds known as pyrroloindoles. Pyrroloindoles are compounds containing a pyrroloindole moiety, which is a tricyclic heterocycle which consists of a pyrrole ring fused to an indole. Pyrrole is 5-membered ring consisting of four carbon atoms and one nitrogen atom. Indole is a bicyclic compound consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. Leptosine is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Leptosine can be found in american cranberry, which makes leptosine a potential biomarker for the consumption of this food product.
