Biological Activity

Description Yohimbine (Antagonil) has been used as a mydriatic and in the treatment of impotence. It is also alleged to be an aphrodisiac.
Targets
alpha 2-adrenergic receptor [2]
In vitro Yohimbine(Antagonil) has been used as a mydriatic and in the treatment of impotence. It is also alleged to be an aphrodisiac. [1] Yohimbine is a pre-synaptic alpha 2-adrenergic blocking agent. 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.

In vivo LD50: Mice 55mg/kg (i.p.) [3]
