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).

MMPs, Matrix metalloproteinases: Click to Expand ⟱

Source:

Type:

Family of zinc-dependent proteolytic enzymes that play a key role in degrading the extracellular matrix (ECM).; are metalloproteinases that are calcium-dependent zinc-containing endopeptidases;[1] other family members are adamalysins, serralysins, and astacins. The MMPs belong to a larger family of proteases known as the metzincin superfamily.[2]
MMP secretion: matrix metalloproteinase (MMP) is a kind of enzymes secreted.
by tumor cell to degrade ECM, facilitating the migration of tumor cells.

MMPs are generally considered protumorigenic due to their role in promoting tumor invasion, metastasis, and angiogenesis. They facilitate the breakdown of the extracellular matrix, allowing cancer cells to invade surrounding tissues and spread to distant sites.

Silymarin: Unveiling its pharmacological spectrum and therapeutic potential in liver diseases—A comprehensive narrative review

Review,

NA,

*antiOx↑, silymarin, demonstrating remarkable antioxidant and hepatoprotective properties in extensive preclinical investigations.
*hepatoP↑, It can protect healthy liver cells or those that have not yet sustained permanent damage by reducing oxidative stress and mitigating cytotoxicity.
*Half-Life↑, The main ingredient in silymarin, silibinin, normally takes two to four hours to reach its peak plasma concentration after oral consumption, and it has a 6‐hour plasma half‐life
*ROS↓, silibinin has potent anti‐ROS qualities,
*GSH↑, silymarin, the precursor to silibinin, can increase glutathione production in the liver and hence increase the liver tissues' antioxidant capacity
*hepatoP↑, silymarin, the precursor to silibinin, can increase glutathione production in the liver and hence increase the liver tissues' antioxidant capacity
*lipid-P↓,
*TNF-α↓, inhibit the production of pro‐inflammatory cytokines, such as TNF‐α, IFN‐γ, IL‐2, and IL‐4, which are crucial in the inflammatory cascade
*IFN-γ↓,
*IL2↓,
*IL4↓,
*NF-kB↓, Silymarin's mechanism involves suppressing NF‐κB activation,
*iNOS↓, It downregulates inflammatory mediators like interleukins, TNF‐α, and iNOS, which are involved in various diseases.
*OATPs↓, Its inhibition of transporters, including OATPs and OCTs, may also affect members of the solute carrier family
*OCT4↓,
*Inflam↓, Silymarin may have anti‐inflammatory properties that limit the production of inflammatory mediators like NF‐B and inflammatory metabolites like prostaglandin E2 (PGE2)
*PGE2↓,
MMPs↓, Silymarin significantly inhibits matrix metalloproteinases (MMPs), essential for cancer metastasis,
VEGF↓, Additionally, silymarin down‐regulates VEGF expression, contributing to anti‐angiogenic effects, and has the potential to reverse STAT‐3‐associated cancer drug resistance.
angioG↓,
STAT3↓,
*ALAT↓, The research revealed improved liver function as seen by lower levels of ALT, AST, and alkaline phosphatase, as well as a considerably lower likelihood of developing DILI four weeks after starting silymarin treatment
*AST↓,
Dose↝, The suggested dosage of silymarin has been used in clinical trials for up to 48 weeks at a dose of 2100 mg/day and for up to 4 years at a dose of up to 420 mg/day.
