Application

Yohimbine hydrochloride has been:
  • used to study its in vitro antiviral, antibacterial and antifungal activities and cytotoxicity
  • used as a tyramine receptor blocker to oppose the effects of increased tyramine in relation with flight initiation and maintenance deficits in experimental flies
  • used alone and as well as with brimonidine to study the neuroprotective effect of brimonidine in the presence of glutamate-induced neurotoxicity, oxidative stress and hypoxia on in vitro cultures of purified rat retinal ganglion cells

Biochem/physiol Actions

Yohimbine is derived from the Coryanthe yohimbe tree cortex. It is an alkaloid. Yohimbine hydrochloride is an α2-adrenergic receptor antagonist. It blocks the central α2-adrenergic receptors in the brain, thus preventing and reducing the effects of xylazine, an α2-adrenergic agonist. The sedative effects and respiratory depression that accompany xylazine administration are both antagonized and reversed by yohimbine. Yohimbine hydrochloride also produces an antidiuretic effect, and increases heart rate and blood pressure. It is useful in treating erectile dysfunction and promotes sexual functioning.

In line with the idea that cholecystokinin (CCK) is involved in anxiety-related behaviours, previous investigations showed that stressful conditions and an 'anxiogenic' drug, yohimbine, increased the cortical release of CCK like-material (CCKLM) in awake rats, and that this effect could

Intracellular calcium ([Ca(2+)]i) influx through N-methyl-d-aspartic acid (NMDA) receptors in cortical neurons is central to NMDA receptor-mediated excitotoxicity. Drugs that uncompetitively modulate NMDA receptor-mediated [Ca(2+)]i influx are potential leads for development to treat NMDA receptor-mediated neuronal damage since these drugs
