Stephanine
Catalog No: CFN98828

l-Stephanine is a potent and highly selective alpha 1 adrenoceptor blocker, inhibits anococcygeus muscle contraction induced by phenylephrine with pA2 values of 6.76. Stephanine shows significant antiplasmodial activities with IC(50) ranged from 1.2 uM to 52.3 uM. Stephanine and crebanine have high inhibitory activity against gram-positive animal pathogenic bacteria, with MIC values of 0.078-0.312g/l, but low inhibitory activity against gram-negative animal pathogenic bacteria, they also inhibit hyphal growth of the plant pathogens Cercospora kaki.

Steppogenin
Catalog No: CFN98949

Steppogenin exhibits significant tyrosinase inhibition activity, it also shows strong mushroom tyrosinase inhibitory activity with IC(50) values lower than 50 microM, more potent than kojic acid (IC(50) = 71.6 microM), a well-known tyrosinase inhibitor.

Sterebin A
Catalog No: CFN91078

Sterebin A may have anti-inflammatory activity.

Sterebin E
Catalog No: CFN91079

Sterebin E may have anti-inflammatory activity.

Stevenleaf
Catalog No: CFN99189

1. Gypenosides (Gyp, Stevenleaf) induce apoptosis in human hepatoma cells through the up-regulation of Bax and Bak, and down-regulation of Bcl-2, release of mitochondrial cytochrome c and activation of caspase cascade.
2. Gypenosides induce ER stress and production of reactive oxygen species and Ca 2+ , change the ratio of Bcl-2 and Bax, followed by the dysfunction of mitochondria, cause cytochrome c release, activation of caspase-3 before leading to apoptosis, these results provide information towards an understanding of the mechanisms by which Gyp induces cell cycle arrest and apoptosis in human tongue cancer cells.
3. Gypenosides can inhibit invasion and migration of human tongue SCC4 cells by down-regulating proteins associated with these processes, resulting in reduced metastasis.
4. Gypenosides imply their remarkable preventative and therapeutic potential in treatment of neurological diseases involving glutamate and oxidative stress.
5. The extensive antioxidant effect of gypenosides may be valuable to the prevention and treatment of various diseases such as atherosclerosis, liver disease and inflammation.

Steviol
Catalog No: CFN93068

Steviol, a natural sweetener, it inhibits proliferation of the gastrointestinal cancer cells intensively. Steviol can treat polycystic kidney disease, it slowed cyst growth, in part, by reducing AQP2 transcription, promoted proteasome, and lysosome-mediated AQP2 degradation. Steviol can induce a significant increase in CYP3A29 expression.

Steviolbioside
Catalog No: CFN96485

Steviolbioside is a natural sweetener, it presents notable inhibition on human hepatocarcinoma cell Hep3B, human breast cancer cell MDA-MB-231 and human pancreatic cancer cell BxPC-3, thus, steviolbioside could be a potential remedy for human breast cancer. Steviolbioside also exhibits moderate antituberculosis activity against M. tuberculosis strain H37RV in vitro.

Stevioside
Catalog No: CFN99548

Stevioside is a safe natural sweetener, has no allergic reactions, suited for both diabetics, and PKU patients, as well as for obese persons intending to lose weight by avoiding sugar supplements in the diet. Stevioside enjoys a dual positive effect by acting as an antihyperglycemic and a blood pressure-lowering substance, it may have therapeutic potential in the treatment of type 2 diabetes and the metabolic syndrome.Stevioside exerts anti-inflammatory and anti-apoptotic properties by inhibiting the release of cytokines and the activation of TLR2 and proteins of the NF-κB and MAPK signaling pathways, as well as caspase-3 and Bax.

Stigmast-4-ene-3,6-dione
Catalog No: CFN98968

Stigmast-4-ene-3,6-dione has anti-inflammatory and anti-allergic properties.

Stigmast-7-en-3-ol
