Vincamine is a monoterpenoid indole alkaloid found in the leaves of Vinca minor (lesser periwinkle), comprising about 25–65% of its indole alkaloids by weight. It can also be synthesized from related alkaloids.[1]

Uses

edit

Vincamine is sold in Europe as a prescription medicine for the treatment of primary degenerative and vascular dementia.[citation needed] In the United States, it is permitted to be sold as a dietary supplement when labeled for use in adults for six months or less.[2] Most common preparations are in the sustained release tablet forms.

Chemistry

edit

Synthesis

edit

Tabersonine can be used for semi-synthesis of vincamine.[3]

Derivatives

edit

Vinpocetine is a synthetic derivative of vincamine used for cerebrovascular diseases and as dietary supplement.[4] Vincamine derivatives have been also studied as anti addictive[5] and antidiabetic[6] agents.

Research

edit

It may have nootropic effects.[3] It has been investigated as novel anticancer drug.[7]

Concerns over long-term use have been documented by the US National Toxicology Program.[8]
