WP9QY
Based on 1 Customer Validation
WP9QY is an inhibitor targeting TNFα and RANKL, which blocks the TNFα-TNFR1 interaction and inhibits TNFα-mediated apoptosis, cytotoxicity and bone destruction. WP9QY inhibits osteoclastogenesis and promotes osteoblast differentiation, induces chondrocyte proliferation and glycosaminoglycan production, and synergizes with TGF-β3 to promote chondrogenesis. WP9QY effectively repairs full-thickness articular cartilage defects in rabbits via intra-articular injection, and inhibits methylmercury-induced reduction of NeuN-positive cells in mouse brain slices. WP9QY can be applied to the research of diseases related to methylmercury-induced neuronal death, cartilage injury, osteoarthritis and bone loss.

Biological Activity
WP9QY-functionalized PEG hydrogels (100-250 μM; 24 h TNFα exposure, 6 d NGF differentiation culture) protect differentiated PC12 cells from apoptosis induced by 50 ng/mL human TNFα, maintain cell viability, and prevent the elevation of caspase 3/7 activation levels[1].
WP9QY-functionalized PEG hydrogel (100 μM; 24 h) protects encapsulated mouse islets from 50 ng/mL human TNFα-induced apoptosis and impaired insulin secretion, and maintains cell viability and function[1].
WP9QY (10 μM; 72 h) inhibits neuronal cell death induced by 50 μM methylmercury in cultured mouse organotypic brain slices in vitro[2].
WP9QY (100 μM; 14 d) significantly enhances chondrogenic differentiation of hMSCs in a two-dimensional culture system via accumulation of glycosaminoglycan matrix, as confirmed by Alcian Blue staining (HY-D0001) and absorbance measurement[3].
WP9QY (25-100 μM; 72 h) dose-dependently promotes the proliferation of hMSCs cultured in maintenance medium, chondrocyte differentiation medium, and osteoblast differentiation medium, and this result is confirmed by Hoechst 33342 (HY-15559) fluorescence assay[3].
WP9QY (100 μM; 14 d) induces chondrocyte differentiation in both control and RANKL-knockdown C3H10T1/2 cells in a RANKL signaling-independent manner[3].
WP9QY (5-50 μM; 20 min) dose-dependently inhibits RANKL-induced signaling pathways in RAW 264.7 cells, without affecting M-CSF-induced signaling pathways[4].
