生物活性

(S)-Trolox is an analogue of vitamin E, in which the phytyl chain is replaced with a carboxyl group. (S)-Trolox is frequently used as a model compound for studies of structural features, as well as a standard for evaluation of antioxidant activity. (S)-Trolox has potent and specific neuroprotective and antioxidant effects.

体外研究

The neuroprotective efficacy of antioxidant molecules against iodoacetate (IAA) neurotoxicity in rat cerebellar granule cell (CGC) cultures is investigated. In the absence of MK-801, (S)-Trolox displays marginal neuroprotective effects. In the presence of MK-801 (10 μM), the neuroprotective efficacy of (S)-Trolox is greatly enhanced, giving rise to a recovery in MTT-reductase activity equivalent to 80–100% of control cultures. (S)-Trolox displays EC50 value of 78 μM. The fluorescence increase in IAA-stimulated DCFH-DA-loaded cultures is inhibited in a dose-dependent manner by the antioxidants (S)-Trolox with an IC50 value of 97 μM. The antioxidant (S)-Trolox demonstrate apotent and specific neuroprotective action in an in vitro model of neurodegeneration induced by inhibition of the glycolytic enzyme GAPDH.

  • 1.

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

    Solubility: ≥ 2.5 mg/mL (9.99 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (9.99 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。
