What is Silydianin?
Description
Silydianin is a flavonolignan found in S. marianum and has diverse biological activities. It inhibits tyrosinase (IC50 = 2.6 μM for the mushroom enzyme) and scavenges DPPH radicals in a cell-free assay (IC50 = 66.8 μM). Silydianin (100 μM) protects against cytotoxicity induced by allyl alcohol, carbon tetrachloride, paracetamol (acetaminophen), or D-galactosamine in primary human hepatocytes. It inhibits the proliferation of DU145 and PC3 prostate cancer cells when used at a concentration of 90 μM. Silydianin (1%) prevents methacholine-induced airway hyperresponsiveness (AHR) and reduces blood and bronchoalveolar lavage fluid (BALF) levels of eosinophils in an ovalbumin-sensitized mouse model of allergic asthma when administered via inhalation.
Originator
Silydianin was isolated for the first time by G. M schlin during initial experiments with S. marianum fruits as a compound named E5.
The Uses of Silydianin
Silydianin is an active constituent of Silybium marianum and is known the exhibit anti-inflammatory activity which regulates caspase-3 activation which affects cell membranes and acts as a free radica l scavenger.

Cytotoxicity
Cell suspensions were incubated with different concentrations of silydianin (up to a final concentration of 1–100 μM) for 30 min at 37 °C in a dark incubator and untreated control samples. The samples were then centrifuged at 800–900 rpm, PMNs were resuspended in RPMI 1640, and 0.4% trypan blue and the viable and dead cells were scored. The cell viability was 94.8 ± 3.8% for silydianin at concentrations of 1–100 μM, indicating no cytotoxicity toward neutrophils[2].
