Sedanolide is a natural phthalide first isolated from seed oil of the Umbelliferae family, including celery.

Sedanolide suppressed J5 cell viability by inducing autophagy. Phosphoinositide 3-kinase (PI3K)-I, mammalian target of rapamycin (mTOR) and Akt protein levels decreased, whereas PI3K-III, LC3-II and Beclin-1 protein levels increased following Sedanolide treatment in J5 cells. In addition, Sedanolide treatment upregulated nuclear p53 and damage-regulated autophagy modulator (DRAM) and downregulated cytosolic p53 and Tp53-induced glycolysis and apoptosis regulator (TIGAR) expression in J5 cells. Furthermore, the cytosolic phosphorylation of inhibitor of kappa B (IκB) and nuclear p65 and the DNA-binding activity of NF-κB increased after Sedanolide treatment. These results suggest that Sedanolide induces J5 cell autophagy by regulating PI3K, p53 and NF-κB autophagy-associated signaling pathways in J5 cells.
