SIL, Silymarin (Milk Thistle) silibinin: Click to Expand ⟱

Features:

Silymarin (Milk Thistle) Flowering herb related to daisy and ragweed family.
Silibinin (INN), also known as silybin is the major active constituent of silymarin, a standardized extract of the milk thistle seeds.
-a flavonoid combination of 65–80% of seven flavolignans; the most important of these include silybin, isosilybin, silychristin, isosilychristin, and silydianin. Silybin is the most abundant compound in around 50–70% in isoforms silybin A and silybin B

-Note half-life 6hrs?.
BioAv not soluble in water, low bioA (1%). 240mg yielded only 0.34ug/ml plasma level. oral administration of SM (equivalent to 120 mg silibinin), total (unconjugated + conjugated) silibinin concentration in plasma was 1.1–1.3 μg/mL, so can on acheive levels used in most in-vitro studies.
Pathways:
- results for both inducing and reducing ROS in cancer cells. In normal cell seems to consistently lower ROS. Given low bioavailability seems unlikely one could acheieve levels in vivo to raise ROS(except level in GUT could be much higher (800uM).

α-SMA, α-smooth muscle actin: Click to Expand ⟱

Type: protein

α-smooth muscle actin (α-SMA) is a protein that is often associated with cancer progression. It is a key component of the actin cytoskeleton and plays a crucial role in cell migration, invasion, and contraction.
α-SMA is often expressed by cancer-associated fibroblasts (CAFs), which are a type of stromal cell that surrounds the tumor. CAFs expressing α-SMA can promote tumor growth and metastasis.
High levels of α-SMA expression have been correlated with poor prognosis in various types of cancer, including breast, lung, and colorectal cancer.

Silymarin: a review on paving the way towards promising pharmacological agent

Review,

Nor,

Review,

Arthritis,

*hepatoP↑, It improves hepatic function, lessens hepatotoxicity caused by high acetaminophen intake, and can lessen oxidative stress in experimental mice, according to a study on animals
*Inflam↓,
*chemoP↑, moreover reducing the side effect of chemotherapeutic agents.
*glucose↓, Silymarin is effective anti-diabetic as it lowers serum glucose levels thus preventing the development of diabetic nephropathy
*antiOx↑, Various studies revealed that Silymarin could exert antioxidant properties in several mechanisms, which includes direct hindrance in free radical production,
*ROS↓,
*ACC↓, down-regulation of acetyl-CoA carboxylase, fatty acid synthase, and peroxisome proliferator-activated receptor
*FASN↓,
*radioP↑, More studies have revealed radioprotective properties of Silymarin in the testis tissues of mice and rats
*NF-kB↓, Silymarin inhibits NF-kB, down-regulates TGF-ß1 mRNA
*TGF-β↓,
*AST↓, Silymarin significantly decreased the elevation of aspartate aminotransferase (AST), alanine aminotransferase, and alkaline phosphatase in serum, and also reversed the altered expressions of α-smooth muscle actin in fibrotic tissue
*α-SMA↝,
*eff↑, Okda et al.[Citation76] currently reported that silymarin with ginger has significantly decreased the severity and incidence of liver fibrosis.
*neuroP↑, Researchers demonstrated that silymarin inhibits microglia activation, and protects dopaminergic neurons from lipopolysaccharide (LPS)-induced neurotoxicity
eff↑, The Silymarin with a selenium dose of 570 mg/d, for 6 months caused no side effects and was effective in reducing prostate cancer growth
ROS↓, Silymarin shows anti-cancerous properties considered to be linked to oxidative stress inhibition, apoptosis induction, growth cycle arrest, and mitochondrial pathway inhibition

Hepatoprotective effect of silymarin

Review,

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
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.
