生物活性

Dehydroepiandrosterone sulfate, a neuroactive neurosteroid, plays a major role in brain development and aging by influencing the migration of neurons, arborization of dendrites, and formation of new synapses.

体外研究

Dehydroepiandrosterone sulfate (DHEAS) selectively increased the length of neurites containing the dendritic marker MAP-2.
Dehydroepiandrosterone sulfate (DHEAS) has been reported to increase neuronal excitability (firing rate) when directly applied to septal-preoptic neurons.
Dehydroepiandrosterone (DHEA) is produced in prodigious quantities by the human adrenal, principally as the 3-sulfoconjugate DHEA sulfate (DS) during intrauterine life.
Dehydroepiandrosterone sulfate (DHEAS) is generally nontoxic and lacks adverse side effects even when it is administered chronically.

体内研究

DHEAS chronic administration produces a dose-dependent effect on performance.

Animal Model: Sixty-four male Sprague-Dawley rats, approximately 90 days of age (300-400 g).
Dosage: 5, 10, or 20 mg/kg.
Administration: Subcutaneous injection starting 7 days post-surgery and 1 h prior to all behavioral testing.
Result: Significantly effective in improving latency to reach the platform as compared to injured rats receiving vehicle.

  • 1.

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% saline

    Solubility: ≥ 2.5 mg/mL (6.78 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (6.78 mM,饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in saline)

    Solubility: ≥ 2.5 mg/mL (6.78 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (6.78 mM,饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例,取 100 μL 25.0 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。
