Sarpagine is primarily studied for its biological activity, particularly in the field of pharmacology. It exhibits antihypertensive properties by acting as a vasodilator, helping to lower blood pressure through relaxation of vascular smooth muscle. The compound also shows potential as an antiarrhythmic agent, influencing cardiac rhythm regulation. Additionally, sarpagine has demonstrated antimicrobial and anti-inflammatory effects in preliminary studies, making it a subject of interest for drug development. Its ability to interact with central nervous system receptors may contribute to sedative or neuroprotective applications, though further research is needed to fully explore these effects in clinical settings.
