生物活性

Withanolide B is an active component of W. somnifera Dunal. Withanolide B promotes osteogenic differentiation of hBMSCs via ERK1/2 and Wnt/β-catenin signaling pathways. Withanolide B exhibits neuroprotective, anti-arthritic, anti-aging and anti-cancer effects[1][2][3].

体外研究
(In Vitro)

Withanolide B (1-100 nM; 3-5 days) significantly increases the expression of COL1A1 and RUNX2 genes and proteins in hBMSCs[1].
Withanolide B (1-100 nM; 11 or 3 days) increases the formation of extracellular matrix calcium deposits and increased the activity of alkaline phosphatase (ALP)[1].
Withanolide B (1-100 nM; 3-5 days) increases the protein expressions of p-ERK and active β-catenin of hBMSCs[1].
Withanolide B (10-100 μM; 48 h) reverses the Aβ42 aggregation-induced toxicy in SK-N-SH cells[2].

Cell Viability Assay[1]

Cell Line: Human bone mesenchymal stem cells
Concentration: 1, 10, 100 nM
Incubation Time: 3, 5 days
Result: Significantly increased the expression of COL1A1 and RUNX2.

体内研究
(In Vivo)

Withanolide B (10 mg/kg; topical administration) promotes bone healing in a rat tibial defect model[1].

Animal Model: Male Sprague-Dawley rats (8 weeks, 200 g) with tibial defect[1]
Dosage: 10 mg/kg
Administration: Injected in situ at the bone defect site at different time points (0, 3, 5, 7, and 9 days)
Result: Increased the trabecular number, trabecular thickness and the thickness of the cortical bone.
