Withanolide B, a natural product isolated from Withania somnifera Dunal, promotes osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (hBMSCs) via the ERK1/2 and Wnt/β-catenin signalling pathways, thereby enhancing bone healing. Withanolide B exhibits affinity for the catalytic domain of PARP-1.

| Targets&IC50 | SK-N-SH cells:14.84±1.45 μM |
| In vitro | Methods: SK-N-SH cells were treated with Withanolide B (10-100 μM, 48 hours), and cell viability was assessed using the MTT assay. Results: The IC50 value of Withanolide B for SK-N-SH cells was 14.84±1.45 μM, indicating that Withanolide B exhibits low toxicity to neuronal cells. [1] |
| In vivo | Methods: By injecting Withanolide B (10 mg/kg) into the bone defect site of the SD rat tibial osteotomy model, the effect of Withanolide B on the osteogenic differentiation of hBMSCs was investigated. Results: Micro-CT scanning and histological analysis demonstrated that Withanolide B significantly promoted the healing of bone defects. [2] |
