生物活性

Vinpocetine (Ethyl apovincaminate) is a derivative of the alkaloid Vincamine that blocks voltage-gated Na channels. The IC50 value of Vinpocetine on direct IKK inhibition in the cell-free system is 17.17 μM. Vinpocetine is a phosphodiesterase (PDE) inhibitor and inhibits NF-κB-dependent inflammatory responses by directly targeting IκB kinase complex (IKK), and has been widely used for the treatment of cerebrovascular disorders.

体外研究

Vinpocetine (5-50 μM; 7 hours; VSMCs, HUVECs, A549 cells and RAW264.7 cells) potently inhibits TNF-α-induced NF-κB-dependent transcriptional activity in a dose-dependent manner with an approximate IC50 value of 25 μM. Vinpocetine do not have a significant effect on cell viability.
Vinpocetine (50 μM; 7 hours; VSMCs, HUVECs, A549 cells and RAW264.7 cells) potently inhibits TNF-α-induced up-regulation of TNF-α, IL-1β, IL-8, MCP-1, VCAM-1, ICAM-1and MIP-2 transcripts in several cell types.

RT-PCR

Result: Inhibited TNF-α-induced up-regulation of TNF-α, IL-1β, IL-8, MCP-1, VCAM-1, ICAM-1and MIP-2 transcripts in several cell types.
体内研究

Vinpocetine (2.5-10 mg/kg; intraperitoneal injection; C57BL/6 mice) potently inhibits TNF-α- or LPS-induced up-regulation of proinflammatory mediators, including TNF-α, IL-1β, and MIP-2, and decreases interstitial infiltration of polymorphonuclear leukocytes in a mouse model of TNF-α- or LPS-induced lung inflammation.

Animal Model: C57BL/6 mice (8 weeks of age)
Dosage: 2.5 mg/kg, 5 mg/kg, and 10 mg/kg
Administration: Intraperitoneal injection
Result: Inhibited TNF-α- or LPS-induced up-regulation of proinflammatory mediators, including TNF-α, IL-1β, and MIP-2, and decreased interstitial infiltration of polymorphonuclear leukocytes in a mouse model of TNF-α- or LPS-induced lung inflammation.
