OBJECTIVE Vincamine is a plant alkaloid used clinically as a peripheral vasodilator that increases cerebral blood flow and oxygen and glucose utilization by neural tissue to combat the effect of aging. The main purpose of the present study is to investigate the influence of vincamine on amyloid-β 25-35 (Aβ25-35) induced cytotoxicity, to gain a better understanding of the neuroprotective effects...

Microbial transformation is a complementary tool in the investigation of drug metabolism. In the present investigation, biotransformation of vincamine was studied using microbial cultures. Bacterial, fungal, and yeast cultures were employed to elucidate the metabolism of vincamine. The results indicate that a number of microorganisms metabolized vincamine to various levels to yield three major ...

Lesser Periwinkle (Vinca minor L.), a member of Apocynaceae, is not only an ornamental plant with lilac-blue flowers, but also a medical plant producing an important alkaloid, vincamine, found in the leaves which shows a pronounced cerebrovasodilatory and neuroprotective activity. This plant is native to northern Spain, western France, central and southern Europe, and Caucasus. It has been rece...

The ion-molecule reactions of ions from acetone, dimethyl ether, 2-methoxyethanol, and vinyl methyl ether with vincamine were investigated. Reactions with dimethyl ether result in [M+13](+) and [M+45](+) products, reactions with 2-methoxyethanol produce [M+13](+) and [M+89](+) ions, and reactions with acetone or vinyl methyl ether ions generate predominantly [M+43](+) ions. Collision-activated ...

The role of oxidative stress is known among the patients diabetes as level reactive oxygen species was high diabetic patients. This generated in due to continuous glucose levels that cause decrease defence mechanism for antioxidant enzymes within body. reduction leads towards generation hydroxyl radicals consequently results lipid peroxidation. objective this study examine efficacy Vincamine ex...

An easy, rapid and selective adsorptive stripping voltammetry (AdSV) method for the determination of vincamine in its formulation and human serum was developed and validated. It was based on the oxidation of the drug onto a Nujol-based carbon paste electrode. The stripping step was carried out by using a square-wave (SW) potential-time voltammetric excitation signal. The optimal experimental va...
