Usage

Uses

(3R,14S,16S)-Vincamine is a diastereomer of Vincamine (V314030) which is often used as a nootropic agent to combat the effects of aging, or in conjunction with other nootropics (such as piracetam) for a variety of purposes. Vincamine is a peripheral vasodilator that increases blood flow to the brain.

Preparation methods for chiral impurities of vincamine

The invention relates to preparation methods for chiral impurities of vincamine. Through oriented synthesis method and the later column chromatography separation, high purity product of seven chiral impurities can be obtained, and the preparation methods can be used for the qualitative and quantitative analysis of impurities in the production of vincamine, so that the separation and confirmation of the seven chiral impurities in vincamine drugs can be realized, and the drug standard of the vincamine can be enhanced, and therefore, the vincamine with high purity can be obtained. Compared with existing preparation methods for the vincamine, the preparation methods relate to the preparation of seven chiral isomers, and are more complete and simpler in operation.

Syntheses and Cardiovascular Activity of Stereoisomers and Derivatives of Eburnane Alkaloids

The synthesis of all the possible isomers of the eburnamenine-vincamine type alkaloids 1b, 2a*, 3a and derivatives 4, 8, 9, 10 is described.Structures were determined by 1H- and 13C-NMR spectroscopy including special techniques such as DR, DEPT, DNOE, and 2D-HSC.In contrast to the known cerebrovascular effects of cis-(3S,16S) compounds, trans-(3S,16R) derivatives show a significant peripheral vasodilator effect.
