Breast cancer (BC) is the most common cancer in women and, among different BC subtypes, triple negative (TN) and human epidermal growth factor receptor 2 (HER2)-positive BCs have the worst prognosis. In this study, we investigated the anticancer activity of the root ethanolic and hexane extracts
Acetylshikonin, a naphthoquinone derivative derived from Lithospermum erythrorhizon, has been shown to have various pharmacological activities; however, its effect on diabetes has rarely been reported. We investigated the hypoglycemic effect of acetylshikonin and found that it decreased blood
This study has demonstrated that acetylshikonin (ACS), the isolated ingredient from Lithospermum canescens Lehm. roots, in a daily dose of 200 microg for 3 days, inhibited cutaneous angiogenesis induced by L-1 sarcoma cells in Balb/c mice.
Lithospermum erythrorhizon has been used for treatment of inflammatory diseases and cancer as a folk remedy. Based on the evidences that anti-inflammatory agents frequently exert antiangiogenic activity, thus we examined comparatively the antiangiogenic activities of three naphthoquinone derivatives
Shikonin derivatives, which are the active components of the medicinal plant Lithospermum erythrorhizon, exhibit many biological effects including apoptosis induction through undefined mechanisms. We recently discovered that orphan nuclear receptor Nur77 migrates from the nucleus to the
Context: Acetylshikonin, a naphthoquinone derivative, is mainly extracted from some species of the family Boraginaceae, such as Lithospermum erythrorhizon Sieb. et Zucc., Arnebia euchroma (Royle) Johnst., and Arnebia
Although acetylshikonin (ACS) is known to have antioxidant and antitumor activities, whether ACS regulates the expression of proinflammatory mediators in lipopolysaccharide (LPS)-stimulated microglial cells remains unclear. In this study, it was found that ACS isolated from Lithospermum
OBJECTIVE
Recently, shikonin derivatives from Lithospermum erythrorhizon have been suggested as potential chemotherapeutic agents against numerous types of cancers in addition to their traditional uses, e.g., as anti-inflammatory agents. Acetylshikonin, one of shikonin derivatives, has also been
Zicao (Lithospermum erythrorhizon) has been used in clinics as a traditional Chinese medicine for thousands of years. Acetylshikonin (AS) is the main ingredient of Zicao, Xinjiang, China. The objective of this study was to investigate the anti-obesity and anti-nonalcoholic fatty liver disease
BACKGROUND
Acetylshikonin is one of the biologically active compounds derived from the root of Lithospermum erythrorhizon, a medicinal plant with anti-cancer and anti-inflammation activity. Although there have been a few previous reports demonstrating that acetylshikonin exerts anti-cancer activity
Lithospermum erythrorhizon, which has traditionally been used as a vegetable and to make the liquor Jindo Hongju, contains several naphthoquinone pigments, including shikonin. This study aimed to evaluate the antiobesity effects of Lithospermum erythrorhizon ethanol extract (LE) and elucidate the
Acetylshikonin (AS), a naphthoquinone constituent derived from Lithospermum erythrorhizon, has been revealed various pharmacological activities including anti-oxidative, anti-inflammatory and antifertility effects. Our previous study has illuminated the effects of AS on preventing obesity and
Plants produce a large variety of specialized (secondary) metabolites having a wide range of hydrophobicity. Shikonin, a red naphthoquinone pigment, is a highly hydrophobic metabolite produced in the roots of Lithospermum erythrorhizon, a medicinal plant in the family Boraginaceae. The shikonin
Activity-guided fractionation of a hexane-soluble extract of the roots of Lithospermum erythrorhizon, using a mouse brain monoamine oxidase (MAO) inhibition assay, led to the isolation of two known naphthoquinones, acetylshikonin and shikonin, and a furylhydroquinone, shikonofuran E. These compounds
Five red shikonin pigments, deoxyshikonin, shikonin, acetylshikonin, isobutylshikonin, and beta-hydroxyisovalerylshikonin, were isolated from the roots of Lithospermum erythrorhizon cultivated in Korea. The purified pigments were red, purple, and blue at acidic, neutral, and alkaline pH values,
