Biological Activities

Lithospermum erythrorhizon is a highly valued medicinal plant known for its diverse range of therapeutic properties. Its bioactive compounds, particularly shikonin and its derivatives, demonstrate significant antiviral activity against pathogens such as the Dengue virus and enterovirus 71. Research also highlights the plant's potent anticancer potential, though ongoing studies aim to improve the selectivity of these derivatives to protect healthy cells. Beyond these effects, the plant exhibits notable antibacterial and antifungal activities, showing effectiveness against various yeast-like and filamentous fungi. Furthermore, its role in treating inflammation and providing analgesic relief is well-documented, particularly when used in traditional herbal formulations.

Compounds

Lithospermum erythrorhizon is a medicinal plant renowned for its rich profile of bioactive naphthoquinone derivatives. Among its most significant constituents is shikonin, a primary active component valued for its diverse therapeutic properties. The roots of this plant also contain various other specialized derivatives, including acetylshikonin, deoxyshikonin, and propionylshikonin. Furthermore, the metabolic processes within the plant facilitate the production of lithospermic acid B, a caffeic acid tetramer. Together, these diverse chemical compounds contribute to the plant's significant pharmacological potential in treating skin diseases and fungal infections.

Conditions

Lithospermum erythrorhizon serves as a medicinal plant with significant therapeutic potential, including the ability to treat cancer through the inhibition of adenosine deaminase. It effectively treats inflammation, as demonstrated by its capacity to modulate inflammatory responses and reduce cell infiltration in skin wounds and pancreatitis models. The plant also protects against AP-associated lung injury by reducing damage and cytokine production in mouse models. Furthermore, its derivatives exhibit potent antifungal activity, specifically working to treat C. glabrata with potency comparable to fluconazole. Finally, the plant's constituents are highly effective in treating C. krusei, often demonstrating stronger activity than standard antifungal treatments.

Preparations

Lithospermum erythrorhizon is prepared as cell suspension cultures to produce significant amounts of lithospermic acid B and various shikonin derivatives. This medicinal plant is also prepared as Acetylshikonin (ASK), a naphthoquinone used to regulate gut microbiota and inhibit the transfer of colistin-resistant plasmids. Researchers utilize BK-39 callus culture to study the production of shikonin naphthoquinones. From these initial cell aggregates, selected BK-39F cultures are developed to achieve higher resistance to inhibitors and increased derivative content. Additionally, the plant is prepared as callus to derive exosome-like vesicles that possess anti-inflammatory and regenerative properties for wound healing.
