Yohimbine
Yohimbine is an indole alkaloid with alpha2-adrenoceptor antagonist activity. It is produced by Corynanthe johimbe and Rauwolfia serpentina. It has a role as an alpha-adrenergic antagonist, a serotonergic antagonist and a dopamine receptor D2 antagonist. It is functionally related to a yohimbic acid. A plant alkaloid with alpha-2-adrenergic blocking activity. Yohimbine has been used as a mydriatic and in the treatment of impotence. It is also alleged to be an aphrodisiac. Yohimbine is an indole alkaloid derived from the bark of the Central African yohimbe tree (Pausinystalia yohimbe) that is widely used as therapy for erectile dysfunction. Yohimbine use has been associated with occasional severe adverse events, but has not been linked to serum enzyme elevations or clinically apparent acute liver injury. Yohimbine is a natural product found in Rauvolfia yunnanensis, Tabernaemontana corymbosa, and other organisms with data available. A plant alkaloid with alpha-2-adrenergic blocking activity. Yohimbine has been used as a mydriatic and in the treatment of ERECTILE DYSFUNCTION. See also: Yohimbine Hydrochloride (active moiety of) ... View More ... Yohimbine is only found in individuals that have used or taken this drug. It is a plant alkaloid with alpha-2-adrenergic blocking activity. Yohimbine has been used as a mydriatic and in the treatment of impotence. It is also alleged to be an aphrodisiac. [PubChem]Yohimbine is a pre-synaptic alpha 2-adrenergic blocking agent. The exact mechanism for its use in impotence has not been fully elucidated. However, yohimbine may exert its beneficial effect on erectile ability through blockade of central alpha 2-adrenergic receptors producing an increase in sympathetic drive secondary to an increase in norepinephrine release and in firing rate of cells in the brain noradrenergic nuclei. Yohimbine-mediated norepinephrine release at the level of the corporeal tissues may also be involved. In addition, beneficial effects may involve other neurotransmitters such as dopamine and serotonin and cholinergic receptors.

vellosimine
Vellosimine is a member of the class of compounds known as macroline alkaloids. Macroline alkaloids are alkaloids with a structure that is based on the tetracyclic macroline skeleton. The macroline skeleton arises by scission of the C-21 to N-4 bond of the akuammilan skeleton, and mostly occurs in bisindole alkaloids. Vellosimine is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Vellosimine can be found in a number of food items such as caraway, italian oregano, star anise, and fox grape, which makes vellosimine a potential biomarker for the consumption of these food products.
