生物活性

JSH-23 is an NF-κB inhibitor which inhibits NF-κB transcriptional activity with an IC50 of 7.1 μM in lipopolysaccharide (LPS)-stimulated macrophages RAW 264.7. JSH-23 inhibits nuclear translocation of NF-κB p65 without affecting IκBα degradation.

体外研究

JSH-2 (1-300 μM; 24 hours) at <100 μM does not show significant cytotoxic effects on the RAW 264.7 cells.
Nuclear amount of NF-κB p65 is markedly increased upon exposure to LPS for 1 h. Treatment of JSH-23 (30 μM; 1 hours) to LPS- stimulated RAW 264.7 cells decreases nuclear content of NF-κB p65 in a dose-dependent manner.

Cell Cytotoxicity Assay

Cell Line: Macrophages RAW 264.7
Concentration: 1, 3, 10, 30, 100, 300 μM
Incubation Time: 24 hours
Result: Did not show significant cytotoxic effects at <100 μM.

Western Blot Analysis

Cell Line: Macrophages RAW 264.7 with LPS-stimulated
Concentration: 30 μM
Incubation Time: 1 hour
Result: Decreased nuclear content of NF-κB p65 in a dose-dependent manner, corresponding to 49±4% inhibition at 3 μM, 75±7% at 10 μM and 95±8% at 30 μM.
体内研究

JSH-23 (1 mg/kg, 3 mg/kg; orally administered; daily; for 2 weeks) significantly reverses the nerve conduction and nerve blood flow deficits seen in diabetic rats.

Animal Model: Male Sprague Dawley diabetic rats (250-270 g)
Dosage: 1 mg/kg, 3 mg/kg
Administration: Orally administered; daily; for 2 weeks
Result: Produced significant improvement in motor nerve conduction velocity (MNCV).

  • 1.

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

    Solubility: ≥ 2.5 mg/mL (10.40 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (10.40 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。
