Background:

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) 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 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
