Massarigenin C is a fungal metabolite that has been found inM. flavoroseaand has enzyme inhibitory activities.1,2Massarigenin C inhibits neuraminidasein vitro(IC50= 4.15 μM).2It is also an inhibitor of yeast α-glucosidase (IC50= 1.25 mM).1It reduces the postprandial peak in blood glucose levels in an oral sucrose tolerance test in normo- and hyperglycemic mice when administered at doses of 3.2, 10, and 31.6 mg kg.
Erigeroside has the protective effects on cerebral ischemia-reperfusion injury in rat, its ability of anti-oxidation and scavenging oxidation free radical may be one of its protective mechanisms.
Hellebrigenin has anti-hepatoma activities, it induces cell cycle arrest and apoptosis in human hepatocellular carcinoma HepG2 cells through inhibition of Akt. Hellebrigenin exhibites moderate to strong activity against human HL-60, SF-295, MDA-MB-435, and HCT-8 cancer cell strains without hemolysis of mouse erythrocytes.
