silymarin

Silymarin is a natural polyphenolic flavonolignan mixture extracted from the seeds of Silybum marianum. It can inhibit tumor cell proliferation and angiogenesis, and improve insulin resistance, thus being widely used in liver disease-related research and adjuvant applications. Studies have shown that silymarin exhibits inhibitory activity against the SARS-CoV-2 main protease, and it has potential research value in the mechanism-related studies of COVID-19.

Silybin A is the major active constituent of silymarin, a standardized extract of the milk thistle seeds, containing a mixture of flavonolignans consisting of silibinin, isosilibinin, silicristin, silidianin and others. Silibinin itself is a mixture of two diastereomers, silybin A and silybin B, in approximately equimolar ratio. Both in vitro and animal research suggest that silibinin has hepatoprotective (antihepatotoxic) properties that protect liver cells against toxins. Silibinin has also demonstrated in vitro anti-cancer effects against human prostate adenocarcinoma cells, estrogen-dependent and -independent human breast carcinoma cells, human ectocervical carcinoma cells, human colon cancer cells, and both small and nonsmall human lung carcinoma cells.

m-PEG3-Tos is a PEG-based PROTAC linker used in the synthesis of Silymarin [1].

m-PEG4-Tos, a PEG-based PROTAC linker derived from silybin ethers, finds application in the synthesis of Silymarin[1].

m-PEG5-Tos is a PEG-based PROTAC linker derived from silybin ethers. This compound serves as an essential component in the synthesis of Silymarin[1].

Tos-PEG8-m, a PEG-based PROTAC linker, is a derivative of silybin ethers. It is utilized in the synthesis of Silymarin[1].

(±)-Taxifolin ((±)-Dihydroquercetin) is the racemate of Taxifolin, a flavonoid with anti-tyrosinase and anti-fibrotic activity, commonly found in onion, silymarin, French maritime pine bark, and Douglas fir bark. It inhibits collagenase with an IC50 value of 193.3 μM and acts as a free radical scavenger with antioxidant capacity.

Silibinin-d3 is the deuterium-labelled compound of silibinin, used for isotope tracing. Silibinin is the primary active component of milk thistle, capable of inhibiting cancer cell proliferation and migration.

Silibinin (Standard) is a reference standard for research and analysis in studies involving Silibinin. Silibinin (Silybin) is the major active constituent of silymarin, a standardized extract of the milk thistle seeds, containing a mixture of flavonolignans consisting of silibinin, isosilibinin, silicristin, silidianin and others.

Silybin B (Standard) is a reference standard for research and analysis in studies involving Silybin B. Silybin B (Silibinin B) is an effective inhibitor of raloxifene 4 '- and 6-glucosalylation, an effective anti-fibrinogenic and anti-oligomeric component of Silymarin, with free radical scavenging activity of 1, 1-diphenyl-2-pyridinyl hydrazine (DPPH), and a protective effect against cisplatin-induced neurotoxicity by alleviating DNA damage and apoptosis. Silybin B can inhibit the growth of human chronic myeloid leukemia K562 cells and induce apoptosis.

Isosilybin B (Standard) is a reference standard for research and analysis in studies involving Isosilybin B. Isosilybin B is a flavonolignan extracted from silymarin that exhibits anti-prostate cancer (PCA) activity, inhibits cancer cell proliferation, and contributes to G1-phase blockade and apoptosis.Isosilybin B induces degradation of the androgen receptor.

Alcesefoliside has statistically significant cytoprotective activity similar to that of silymarin, tested at 60 ug/mL.
