Vincamine

Vincamine (CAS No.: 1617-90-9) is a naturally occurring monoterpenoid indole alkaloid isolated from the leaves of Vinca minor and related species, widely studied in biomedical research for its vasoactive and neurovascular regulatory properties. It functions primarily as a peripheral vasodilator with selective effects on cerebral microcirculation, enhancing regional cerebral blood flow and oxygen delivery, which underpins its investigation in models of cerebrovascular and metabolic disorders. Mechanistically, vincamine has been reported to modulate vascular tone and exhibit activity as a GPR40 agonist, contributing to β-cell protection, improved glucose-stimulated insulin secretion, and enhanced glucose homeostasis in metabolic disease models. In vitro studies indicate pharmacological activity in the low micromolar range in cerebrovascular tissues, supporting its utility in probing smooth muscle responsiveness and microvascular function. Vincamine is commonly employed in cellular and animal studies to investigate neuroprotection, cerebral ischemia, and metabolic regulation, as well as in drug discovery programs targeting vascular dysfunction and type 2 diabetes, with experimental concentrations or dosing regimens varying according to specific study designs and endpoints.
