Description

Biochem/physiol Actions

β,β-Dimethylacrylshikonin (Arnebin-1) is a main active naphthoquinone from herbal plants Lithospermum erythrorhizon (Zicao) and Arnebia euchroma that exhibits anti-neoplasm and antihyperglycemic activities. It stimulates autophagy in lung adenocarcinoma cells through activation of CaMKKβ-AMPK-mTOR pathway. β,β-Dimethylacrylshikonin facilitates wound healing through PI3K pathway. β,β-Dimethylacrylshikonin improves nonalcoholic fatty liver disease induced by a high-fat diet in rats.
