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[1].

IC50 & Target[1]

NF-κB

7.1 μM (IC50, in RAW 264.7 cells)

体外研究
(In Vitro)

JSH-2 (1-300 μM; 24 hours) at <100 μm does not show significant cytotoxic effects on the raw 264.7 cells[1].
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[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Cytotoxicity Assay[1]

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[1]

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
(In Vivo)

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[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

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