Vinpocetine
Vinpocetine

A semisynthetic derivative of vincamine, which is extracted from the
periwinkle plant.
It increases cerebral blood flow and is said to improve memory.[citation
needed]
It is an inhibitor of
phosphodiesterases I and IV, with an IC50 of
approximately 10-5 M.
The substance is widely sold as a supplement; however, there appears to
be some controversy over the possibility of adverse reaction, and low
initial dose is recommended by some retailers. Vinpocetine is included in
many performance-enhancing supplements to help with delivery of
nutrients to muscles after workout[citation needed]. There is one isolated
claim of
agranulocytosis[citation needed].
