| Hazard Information | Back Directory | [Description]
Sciadopitysin is a biflavonoid originally isolated from G. biloba and has diverse biological activities.1,2,3,4 It reduces cytotoxicity induced by amyloid-β (1-42) (Aβ42; Item No. 20574) in PC12 cells (EC50 = 9.84 μM).2 Sciadopitysin (0.1-10 μM) decreases methylglyoxal-induced insulin secretion, production of reactive oxygen species (ROS), cardiolipin peroxidation, and cytotoxicity in RIN-m5F pancreatic β-cells.3 It inhibits P-glycoprotein (P-gp; IC50 = 53.42 μM) and increases cellular toxicity of paraquat and paclitaxel (Item No. 10461) in MDR1-MDCKII cells.5 Sciadopitysin inhibits RANKL-induced mRNA expression of the osteoclast-specific genes CTSK, TRAP, and MMP-9, activation of NF-κB, and osteoclastogenesis in a mouse model of LPS-induced bone loss.4 | [Uses]
Sciadopitysin is a type of biflavonoids in leaves from ginkgo biloba[1]. Sciadopitysi inhibits RANKL-induced osteoclastogenesis and bone loss by inhibiting NF-κB activation and reducing the expression of c-Fos and NFATc1[2]. | [Definition]

Sciadopitysin (i.p.; 10 mg/kg; every other day for 8 days) can reverse the bone loss in LPS-induced mice model (C57BL/6 mice; 6 weeks old)[2]. | [target]
