Biological Activity
Dioscin, a saponin extracted from the root of Polygonatum Zanlanscianense Pamp, can markedly inhibit proliferation of Hela cells, underwent apoptosis in dose- and time-dependent manner.[1]
Dioscin shows remarkable protective effect against acetaminophen-induced liver damage in vitro and in vivo by adjusting mitochondrial function.[2]
Dioscin induces generation of reactive oxygen species through mitochondria dysfunction, is capable of inducing apoptosis in mammalian cells, in which the mitochondria-initiated apoptosis pathway plays an important role.[3]
Dioscin can restore the activity of the anticancer agent adriamycin in multidrug-resistant human leukemia K562/adriamycin cells by down-regulating MDR1 via a mechanism involving NF-κB signaling inhibition.[4]
Dioscin shows little inhibition activity of tyrosinase, whereas oxyresveratrol, a known tyrosinase inhibitor, shows a strong tyrosinase inhibitory activity , and a mixture of oxyresveratrol and dioscin (IC50 = 5.1 and 5.7 μg/ml) highly increases the inhibition of tyrosinase activity with l-tyrosine or l-DOPA as the substrate as compared to either oxyresveratrol (IC50 = 7.8 and 10.9 μg/ml) or dioscin (IC50 > 100 and 100 μg/ml) alone.[5]
Dioscin has been shown to promote anticancer activity against several forms of cancers, it induces apoptosis in cancer cells through the induction of oxidative stress, peroxiredoxins 1and 6 (PRDX 1 and 6) are key targets in the process of dioscin-induced apoptosis that involves intracellular elevated ROS.[6]
Rhizoma Dioscoreae septemlobae (RDSE) and its main component dioscin (DIS) display a weak xanthine oxidase (XO) inhibition activity compared with allopurinol, therefore, they processed uricosuric and nephroprotective actions by regulation of mOAT1, mURAT1 and mOCT2.[7]
