Deferoxamine mesylate是Deferoxamine的甲磺酸盐，它可形成铁络合物并用作螯合剂。Deferoxamine 是一种铁死亡的抑制剂，可在体外低氧和高血糖状态下稳定 HIF-1α 的表达并改善HIF-1α的活性。Deferoxamine 可降低 beta-amyloid (Aβ) 的沉积并诱导自噬。请不要用生理盐水或者PBS配制储存液，可能会产生沉淀。

| 体内研究 | Deferoxamine (100 mg/kg, i.p.) lowers the mortality rate of subarachnoid hemorrhage (SAH) rat. Deferoxamine (100 mg/kg, i.p.) attenuates Evan’s blue extravasation in cortex, ameliorates the tight junction detachment and preserves the integrity of the base membrane examined in electron microscope at day 3 after SAH. Deferoxamine attenuates degradation of BBB proteins after SAH and significantly reduces ferritin expression at day 3 in the cortex, and improves neurologic behavior and cognitive deficits after experimental. Ten µL of 1 mM deferoxamine-treated wounds display significantly accelerated healing from day 7 onward and heal significantly faster than control-treated wounds in diabetic mice. Deferoxamine-treated wounds and dimethyloxalylglycine-treated wounds heal significantly faster than control-treated wounds in aged mice. In deferoxamine (10 mg/mL)-treated TG mice, there is a decrease in both soluble and insoluble Aβ40 and Aβ42. Both pGSK3β and β-catenin are significantly increased by approximately 50% in the deferoxamine-treated mice. |
| 体外研究 | Deferoxamine treatment significantly increases HIF-1α binding under all culture conditions, including hypoxic and high-glucose. The mechanism of deferoxamine is through improving HIF-1α biological function through scavenging oxygen free radicals. Deferoxamine (5 μM) has significant effect on the tumor-associated stromal cells cellular multiplication, and cells die at day 7 after exposure to 50 μM and 100 μM deferoxamine. Deferoxamine (5 μM-100 μM) inhibits the proliferation of BMMSCs, and induces apoptosis of MSCs in a dose-dependent manner. Deferoxamine influences the expression of adhesion proteins on MSCs. Deferoxamine (30, 60, 120 μM) shows lower expression of HIF-1α in a concentration dependent way in AdMSCs. |
