Type:
NF-kB signaling
Nuclear factor kappa B (NF-κB) is a transcription factor that plays a crucial role in regulating immune response, inflammation, cell proliferation, and survival.
NF-κB is often found to be constitutively active in many types of cancer cells. This persistent activation can promote tumorigenesis by enhancing cell survival, proliferation, and metastasis.

Dose↝, oral administration of 240 mg of silybin to 6 healthy volunteers the following results were obtained 377 : maximum\,plasmaconcentration0.34±0.16⁢𝜇⁢g/m⁢L
Half-Life↝, and time to maximum plasma concentration 1.32 ± 0.45 h. Absorption half life 0.17 ± 0.09 h, elimination half life 6.32 ± 3.94 h
BioAv↓, silymarin is not soluble in water and oral administration shows poor absorption in the alimentary tract (approximately 1% in rats,
BioAv↓, Our conclusion is that, from a bioavailability standpoint, it is much easier to achieve migration inhibition, than proliferative reduction.
BioAv↓, Combination with succinate: is available on the market under the trade mark Legalon® (bis hemisuccinate silybin). Combination with phosphatidylcholine:
toxicity↝, 13 g daily per os divided into 3 doses was well tolerated. The most frequent adverse event was asymptomatic liver toxicity.
Half-Life↓, It may be necessary to administer 800 mg 4 times a day because the half-life is short.
ROS↓, its ability as an antioxidant reduces ROS production

- Review, NA, NA
*ROS↓, (1) Direct scavenging free radicals and chelating free Fe and Cu are mainly effective in the gut.
*IronCh↑,
*MMP↑, (2) Preventing free radical formation by inhibiting specific ROS-producing enzymes, or improving an integrity of mitochondria in stress conditions, are of great importance.
*NRF2↑, (3) Maintaining an optimal redox balance in the cell by activating a range of antioxidant enzymes and non-enzymatic antioxidants, mainly via Nrf2 activation
*Inflam↓, (4) Decreasing inflammatory responses by inhibiting NF-κB pathways is an emerging mechanism of SM protective effects in liver toxicity and various liver diseases.
*hepatoP↑,
*HSPs↑, (5) Activating vitagenes, responsible for synthesis of protective molecules, including heat shock proteins (HSPs), thioredoxin and sirtuins
*Trx↑,
*SIRT2↑, increased expression of protective molecules (GSH, Thioredoxins, heat shock proteins (HSPs), sirtuins, etc.)
*GSH↑,
*ROS↑, Similarly, production of O2− and NO in isolated rat Kupffer cells were inhibited by silibinin in a dose-dependent manner, with IC50 80 μM
*NADPH↓, It also decreased the NADPH oxidase, iNOS and NF-κB over expression by As and upregulated the Nrf2 expression in the renal tissue.
*iNOS↓,
*NF-kB↓,
*BioAv↓, active free silibinin concentration in plasma after oral consumption of SM, depending on dose of supplementation, could be in the range 0.2–2.0 μM.
*Dose↝, healthy volunteers, after an oral administration of SM (equivalent to 120 mg silibinin), total (unconjugated + conjugated) silibinin concentration in plasma was 1.1–1.3 μg/mL
*BioAv↑, For example, silibinin concentration in the gut could reach 800 μM

3300- SIL,    Toward the definition of the mechanism of action of silymarin: activities related to cellular protection from toxic damage induced by chemotherapy
- Review, Var, NA
*ROS↓, silymarin and silibinin protect the liver from oxidative stress and sustained inflammatory processes, mainly driven by Reactive Oxygen Species (ROS) and secondary cytokines

3295- SIL,    Hepatoprotective effect of silymarin
- Review, NA, NA
*hepatoP↑, The hepatoprotective and antioxidant activity of silymarin is caused by its ability to inhibit the free radicals that are produced from the metabolism of toxic substances such as ethanol, acetaminophen, and carbon tetrachloride.
*ROS↓,
*GSH↑, Silymarin enhances hepatic glutathione and may contribute to the antioxidant defense of the liver.
*BioAv↝, For example, the level of silymarin absorption is between 20% and 50%. low solubility in water, low bioavailability, and poor intestinal absorption reduce its efficacy
ERK↓, treatment of melanoma cells with silybin attenuated the phosphorylation of extracellular signal-regulated kinase (ERK)-1/2 and RSK2,
NF-kB↓, silybin resulted in the reduced activation of nuclear factor-kappa B (NF-κB), activator protein-1, and STAT3

COX2↓, cytoprotective effect in liver is also caused by the inhibition of the cyclooxygenase cycle
Inflam↓, These affects reduce inflammation
IronCh↑, chelating iron, and slowing calcium metabolism,
lipid-P↓, Silymarin also affects intracellular glutathione, which prevents lipoperoxidation of membranes
ALAT↓, led to significantly reduced levels of alanine aminotransferase (ALT) and aspartame aminotransferase (AST) (AST/ALT < 1)
AST↓,
TNF-α↓, It also reduced the level of TNF-α, which reduces inflammation.
*α-SMA↓, There was also a reduction in FR and reduced markers of fibrosis such as alpha smooth muscle actin, collagen α 1(I), and in the caspase cytotoxicity marker.
*SOD↑, The activity of the enzymes superoxide dismutase (SOD) and glutathione-S-transferase (GST) increased significantly.
