Citreorosein is a cAMP phosphodiesterase inhibitor, it has anti-inflammatory effect, inhibits proinflammatory cytokines production through the inhibition of both MAPKs and AKT-mediated IκB kinase (IKK) phosphorylation and subsequent inhibition of transcription factor NF-κB activation.
Panaxydol has anti-cancer activity, can inhibit the growth and apoptosis of cancer cells, the signaling mechanisms involve a [Ca(2+)](i) increase, JNK and p38 MAPK activation, cAMP, MAP kinase and ROS generation through NADPH oxidase and mitochondria.
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
Fargesone B inhibits the vascular smooth muscle contraction by suppressing the voltage- and receptor-activated calcium influxes in a nonselective manner.
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.
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.
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
Manassantin A is a high potent HIF-1 inhibitor, it protects the gastric mucosa from ethanol-induced acute gastric injury, and suggest that these protective effects might be associated with COX PGE2 stimulation, inhibition of iNOS production and NF-κB act
Licoarylcoumarin is a strong inhibitor of adenosine 3',5'-cyclic monophosphate (cAMP) phosphodiesterase. Licoarylcoumarin has antibacterial effects on the VRE strains; it has anti-HIV activity, and it has inhibitory effects on xanthine oxidase.
ent-3-Acetoxy-labda-8(17),13-dien-15-oic acid have vasorelaxant and hypotensive actions, the mechanisms underlying the cardiovascular actions of the labdane involve the activation of the endothelial NO-cGMP pathway, the opening of K+ channels and the alteration on Ca2+ mobilization.
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
Methyl orsellinate is a phytotoxic compound, it exhibits antifungal activity, it can cause significant inhibition of radicle growth of Amaranthus hypochondriacus and Echinochloa crus-galli, interact with bovine-brain calmodulin and inhibit the activation of the calmodulin-dependent enzyme cAMP phosphodiesterase. Methyl orsellinate can inhibit PTP1B activity with 50% inhibitory concentration values of 277 + - 8.6 microM, the selective inhibition of PTP1B has been widely recognized as a potential drug target for the treatment of type 2 diabetes and obesity, methyl orsellinate may can treat the type 2 diabetes and obesity.
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.
Trans-caffeic acid stearyl ester is posited to inhibit melanogenesis signaling while suppressing cAMP levels and, subsequently, MC1R, MITF, tyrosinase, TRP-2 and TRP-1 down-regulation, resulting in the suppression of tyrosinase activity, DOPA oxidase activity and melanin synthesis.
