Protodioscin
Catalog No: CFN99517

Protodioscin has been shown to exhibit multiple biological actions, such as anti-hyperlipidemia, anti-cancer, sexual effects and cardiovascular properties. It appears to possess aphrodisiac activity probably due to its androgen increasing property, it will be useful in developing health food supplement(s) and/or drug(s) against hyperlipidemia.

Protogracillin
Catalog No: CFN93054

Protogracillin may have inhibitions on platelet aggregation (PAG) and thrombosis.

Protopine
Catalog No: CFN99399

Protopine acts as a potent inhibitor of thromboxane synthesis and PAF with hepatoprotective, antidepressant, antioxidant, antispasmodic and relaxant properties. Protopine is also a novel microtubule-stabilizing agent, causes mitotic arrest and apoptotic cell death in human hormone-refractory prostate cancer cell lines. Protopine blocks phosphorylation of mitogen-activated protein kinases (MAP kinases) and also blocks activation of a nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB).

Protopine hydrochloride
Catalog No: CFN98520

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 MDA-MB-231 cells, and human umbilical vein endothelial cells by changing the expression of adhesive factors.

Protopseudohypericin
Catalog No: CFN90677

Protosappanin A
Catalog No: CFN96956

Protosappanin A has anti-oxidative/nitrative activities on brain immune and neuroinflammation through regulation of CD14/TLR4-dependent IKK/IκB/NF-κB inflammation signal pathway; it exerts anti-neuroinflammatory effect by inhibiting JAK2-STAT3 pathway in lipopolysaccharide-induced BV2 microglia. Protosappanin A induces immunosuppression of rats heart transplantation targeting T cells in grafts via NF-kappaB pathway. Protosappanin A and protosappanin B have antimicrobial activity, they show both alone activities and resistance reversal effects of amikacin and gentamicin against MRSA. Protosappanin A shows strong effect against HIV-1 IN with an IC50 value of 12.6 uM.

Protosappanin B
Catalog No: CFN90135

Protosappanin B possesses antitumor, anti-inflammation and anti-oxidation properties, it protects PC12 cells against oxygen–glucose deprivation-induced neuronal death by maintaining mitochondrial homeostasis via induction of ubiquitin-dependent p53 protein degradation.

Protostemonine
Catalog No: CFN80139

Protostemonine has anti-inflammatory activity, it effectively attenuates LPS-induced inflammatory responses in vitro and in vivo; the beneficial effects are associated with the decreased phosphorylation of MAPK and AKT and the reduced expression of pro-inflammatory mediators, such as iNOS, NO and cytokines. Protostemonine shows significant antitussive activity in a citric acid-induced guinea pig cough model following peripheral administration. It attenuates LPS/GalN-induced acute liver failure and upregulating HO-1 expression is implicated in its hepatoprotective activity. Protostemonine shows strong nematicidal activity against Panagrellus redivevus, with the IC50 value of 0.10 uM.

Protoveratrine A
Catalog No: CFN98521

Protoveratrine A has anti-hypertensive action, it has some effects on cardiovascular and respiratory systems in rats in reducing the blood pressure and heart rate,prolonging the QTc interval,decreasing the respiratory rate and increasing the respiratory width. Protoveratrine A can increase K + uptake from frog skeletal muscle and cause this tissue to release more calcium (Ca ++ ). Protoveratrine A seems to involve at least in part an inhibition of dopaminergic neuron activity, it enhances the release of acetylcholine from the nerve terminals during the resting period and at low frequency of stimulation.
