sedanolide is a natural compound produced in edible umbelliferous plants, such as celery seed oil [1].in hepg2 and caco-2 cells, treatment with sedanolide (7-500 μm) for 24h showed no effect on cell viability. in hepg2 cells cultured in sedanolide-free medium, sedanolide (500 μm) treatment for 72h decreased cell viability. pretreatment with sedanolide (100 μm) for 24 h and exposement to either h2o2 or tbooh did not exhibit statistically significant difference in viability from controls. in hepg2 following 24-h incubation with 500 μm sedanolide, a significant increase in dna strand breaks was observed. sedanolide did not modulate h2o2- and tbooh-induced dna damage. sedanolide was relatively nontoxic to cells in culture [1]. sedanolide (sn) possesses antioxidant effects. in human liver cancer (j5) cells, treatment with sedanolide suppressed j5 cell viability by inducing autophagy. sedanolide decreased protein expression levels of phosphoinositide 3-kinase (pi3k)-i, mammalian target of rapamycin (mtor) and akt and increased pi3k-iii, lc3-ii and beclin-1 protein levels. sedanolide increased the cytosolic phosphorylation of inhibitor of kappa b (iκb) and nuclear p65 and the dna-binding activity of nf-κb. sedanolide induced j5 cell autophagy by regulating pi3k, p53 and nf-κb autophagy-associated signaling pathways in j5 cells [2]. sedanolide (100 μg/ml) inhibited cyclooxygenases-1 and -2 at 250 pg/ml and blocked topoisomerase-i and-ii activity [3].
