Lithospermum erythrorhizon, the purple gromwell, red-root gromwell, 紫草 zicao (Pinyin: zǐcǎo), 紫草 murasaki・sō (Japanese) is a plant species in the genus Lithospermum.
The dried root of Lithospermum erythrorhizon (lithospermum root or Lithospermi Radix, Kanji: 紫根, Katakana: シコン, Pinyin: zǐ gēn, Traditional Chinese: 紫根, Simplified Chinese: 紫根) is a Chinese herbal medicine with various antiviral and biological activities, including inhibition of human immunodeficiency virus type 1 (HIV-1).[1][2]

Biochemistry
The enzyme 4-hydroxybenzoate geranyltransferase utilizes geranyl diphosphate and 4-hydroxybenzoate to produce 3-geranyl-4-hydroxybenzoate and diphosphate. Biosynthetically, alkannin is produced in plants from the intermediates 4-hydroxybenzoic acid and geranyl pyrophosphate. This enzyme is involved in shikonin biosynthesis.
The enzyme geranylhydroquinone 3''-hydroxylase uses geranylhydroquinone, NADPH, H+ and O2 to produce 3-hydroxygeranylhydroquinone, NADP+ and H2O.

- Shikonin exerts anti-inflammatory effects in a murine model of lipopolysaccharide-induced acute lung injury by inhibiting the nuclear factor-kappaB signaling pathway.
- Liang D, Sun Y, Shen Y, Li F, Song X, Zhou E, Zhao F, Liu Z, Fu Y, Guo M, Zhang N, Yang Z, Cao Y.Author information Department of Clinical Veterinary Medicine, College of Veterinary Medicine, Jilin University, Changchun, Jilin Province 130062, People's Republic of China.AbstractShikonin, an analog of naphthoquinone pigments isolated from the root of Lithospermum erythrorhyzon, was recently reported to exert beneficial anti-inflammatory effects both in vivo and in vitro. The present study aimed to investigate the potential therapeutic effect of shikonin in a murine model of lipopolysaccharide (LPS)-induced acute lung injury (ALI). Dexamethasone was used as a positive control to evaluate the anti-inflammatory effect of shikonin in the study. Pretreatment with shikonin (intraperitoneal injection) significantly inhibited LPS-induced increases in the macrophage and neutrophil infiltration of lung tissues and markedly attenuated myeloperoxidase activity. Furthermore, shikonin significantly reduced the concentrations of TNF-α, IL-6 and IL-1β in bronchoalveolar lavage fluid induced by LPS. Compared with the LPS group, lung histopathologic changes were less pronounced in the shikonin-pretreated mice. Additionally, Western blotting results showed that shikonin efficiently decreased nuclear factor-kappaB (NF-κB) activation by inhibiting the degradation and phosphorylation of IκBα. These results suggest that shikonin exerts anti-inflammatory properties in LPS-mediated ALI, possibly through inhibition of the NF-κB signaling pathway, which mediates the expression of pro-inflammatory cytokines. Shikonin may be a potential agent for the prophylaxis of ALI.

Vicent Andrés Estellés s/n, 46100-Burjassot, Valencia, Spain.AbstractShikonin is the major constituent of the root of Lithospermum erythrorhizon, which has been used in traditional Chinese medicine to treat external wounds, burns, or dermatitis for centuries. Nowadays, this root is commonly used as an herbal medicine against cancer. Studies carried out over the past 30 years have demonstrated that many of the effects historically associated with the use of this root have a scientific basis, with shikonin and its derivatives being responsible for its pharmacological properties. These include both anti-inflammatory and anticancer effects. While previous summaries have focused on the pharmacokinetics and toxicity of shikonin, the aim of this review is to report on the most current findings with regard to shikonin's antitumor activity by summarizing and comparing the various studies published in the last ten years and discussing the pharmacological aspects that make shikonin a promising anticancer agent.
