Reaction scheme for total synthesis of the natural product.
The pharmacokinetics and metabolism of vincamine, vinpocetine, methylene-methoxy-apovincaminic acid ester and eburnamine have been reviewed. The main route of elimination for vincamine, vinpocetine and methylene-methoxy-apovincaminic acid ester is ester cleavage and conjugation in the case of eburnamine. Vincamine and its derivatives show significant differences in metabolic pathway and their.
Vincamine, a naturally occurring alkaloid, is a drug which is used for preventive or curative treatment in cerebral circulatory insufficiency. It was originally extracted from Periwinkles (Vincaminor) but is now produced by synthesis or hemisynthesis.

Vincamine (sold under the trademark Oxybral-SR, Figure 12) is a peripheral vasodilator that increases blood flow to the brain can be used as a nootropic agent to combat the effects of aging. Vincamine is an indole alkaloid found in the Vinca minor and Catharanthus roseus. Vincamine can be synthesized in the lab from related alkaloids.
Sources. The Madagascan periwinkle Catharanthus roseus L. is the source for a number of important natural products, including catharanthine and vindoline and the vinca alkaloids it produces from them: leurosine and the chemotherapy agents vinblastine and vincristine, all of which can be obtained from the plant. The newer semi-synthetic chemotherapeutic agent vinorelbine is used in the.
