[Flavonolignans - compounds not only for liver treatment]

Area of Science:

• Phytochemistry
• Pharmacology
• Medicinal Botany

Background:

• Milk thistle (Silybum marianum) contains flavonolignans, the primary bioactive compounds in silymarin.
• Historically used for various ailments, silymarin's hepatoprotective properties have been recognized since the 1970s.
• Flavonolignans consist of a flavonoid (taxifolin) and a phenylpropane (coniferyl alcohol) unit linked by an oxerane ring.

Purpose of the Study:

• To review the diverse health benefits of flavonolignans beyond liver protection.
• To highlight recent research on flavonolignans' biological activities and therapeutic potential.

Main Methods:

• Literature review of scientific studies on flavonolignans from Silybum marianum.
• Analysis of research investigating flavonolignans' effects on cell signaling and metabolism.
• Examination of studies on silybin's interaction with blood coagulation factors and anticancer properties.

Main Results:

• Flavonolignans modulate cell signaling pathways and inhibit arachidonic acid metabolism, reducing inflammation.
• Silybin, a major flavonolignan, inhibits thrombin and FXa, key blood coagulation factors.
• Flavonolignans exhibit potential as anticancer agents.

Conclusions:

• Flavonolignans possess a wide range of health benefits extending beyond liver protection.
• Their anti-inflammatory, anticoagulant, and potential anticancer activities warrant further investigation.
• This review underscores the therapeutic versatility of milk thistle's bioactive compounds.
