Protopine has antiplatelet effects,which is due to inhibition on thromboxane formation and phosphoinositides breakdown and then lead to the decrease of intracellular calcium concentration.Protopine seems to inhibit the heterotypic cell adhesion between MD
Catalponol can enhance dopamine biosynthesis by inducing TH activity and protect against L-DOPA-induced cytotoxicity in PC12 cells, which was mediated by the increased levels of cyclic AMP.
Kushenol A is a kind of Adenosine 3', 5'-cyclic monophosphate(cAMP)phosphodiesterase inhibitiors, it shows selective alpha-glucosidase inhibitory activity. Kushenol A and kushenol C exhibit inhibitory activity against Sodium-dependent glucose cotransporter 2(SGLT2).
Catalpalactone exhibits high antitermitic, and cytotoxic activities, it exhibits potent inhibitory effects on lipopolysaccharide-induced NO synthesis in RAW 264.7 cells , with IC50 values of 9.80 microM. Catalpalactone can inhibit dopamine biosynthesis by
Dodoviscin A may be a new promising pigmentation-altering agent for cosmetic and therapeutic applications, it can inhibit melanin biosynthesis induced by 3-isobutyl-1-methylxanthine and PD98059.Dodoviscin A can promote adipocyte differentiation as charact
Vulpinic and gyrophoric acids are known as ultraviolet filters for natural lichen populations, they can effectively prevent cytotoxic, apoptotic and cytoskeleton alterative activities of 2.5 J/cm(2) UVB in a dose-dependent manner, suggest that vulpinic and gyrophoric acids can be promising cosmetic ingredients to photo-protect human skin cells. Gyrophoric acid also has anti-proliferative/cytotoxic effect.
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.
