Cycloheterophyllin has an antioxidant effect, it is a photoprotective agent that inhibits ultraviolet A (UVA)-induced oxidative stress and damage, and could be used in the research on and prevention of skin photoaging.
Isopedicin has anti-inflammatory functions, it inhibits the O(2)(*)(-) production in human neutrophils by an elevation of cellular cAMP and activation of PKA through its inhibition of cAMP-specific PDE.
Rehmannic acid and oleanolic acetate inhibit succinoxidase activity. Both Rehmannic acid and Icterogenin are potent uncouplers, abolishing the phosphate uptake, the respiration being inhibited by the former and increased by the latter.
Sprengerinin C exerts anti-tumorigenic effects in hepatocellular carcinoma via inhibition of proliferation and angiogenesis and induction of apoptosis, it can strongly suppress tumor angiogenesis in human umbilical vein endothelial cells, it blocks vascul
Cistanoside F shows vasorelaxant, and antioxidative effects, it shows a strong free radical scavenging activity on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and xanthine/xanthine oxidase (XOD) generated superoxide anion radical (O2-.).
8alpha-Tigloyloxyhirsutinolide 13-O-acetate shows inhibitory activity toward CYP2A6 and MAO-A and MAO-B enzymes. 8alpha-Tigloyloxyhirsutinolide 13-O-acetate has anti-cancer activity, it is active against both cancer cell lines (IC50 = 3.50 microM for HT29
