生物活性

Davunetide is an eight amino acid snippet derived from activity-dependent neuroprotective protein (ADNP), a neurotrophic factor that exists in the mammalian CNS. Davunetide possesses neuroprotective, neurotrophic and cognitive protective roperties. Davunetide, a microtubule-stabilizing peptide, interacts with and stabilises neuron-specific βIII-tubulin in vitro. Davunetide penetrates the blood-brain barrier and is non-toxic. Davunetide inhibits Aβ aggregation and Aβ-induced neurotoxicity.

体内研究

Davunetide (2 μg/kg; Intranasally; daily, 5 days a week, for 16 weeks) shows protective effects for central nervous system complications in a diabetes rat model.

Animal Model:	Male Sprague-Dawley rats (Induced by an i.p. streptozotocin (STZ) injection)
Dosage:	2 μg/kg
Administration:	Intranasally beginning on the day following the STZ injection and were given daily, 5 days a week, for 16 weeks
Result:	Impaired spatial memory of the diabetic rats was observed in the water maze by attenuated learning curve and worsened performance in the probe memory test. Davunetide treatment significantly improved both measurements.

In Vivo:

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：

——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用；以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

1.

请依序添加每种溶剂： 10% DMSO 90% (20% SBE-β-CD in saline)
Solubility: ≥ 2.08 mg/mL (2.52 mM); Clear solution

此方案可获得 ≥ 2.08 mg/mL (2.52 mM，饱和度未知) 的澄清溶液。
以 1 mL 工作液为例，取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中，混合均匀。
