acanthopanax koreanus/phosphatase

Inhibition of protein tyrosine phosphatase 1B (PTP1B) has been proposed as a therapy to treat type 2 diabetes and obesity. In our preliminary screening study on the PTP1B inhibitory activity, a CH2Cl2-soluble extract of the roots of Acanthopanax koreanum (Araliaceae) was found to inhibit PTP1B

New neo-lignan, (7S, 8R)-3-hydroxyl-4-methoxyl-balanophonin (1), together with seven known compounds (2-8) were isolated from the EtOAc-soluble extract of Acanthopanax senticosus. The structure of the new neo-lignan was elucidated with spectroscopic and physico-chemical analyses. All the isolates

Non-alcoholic fatty liver disease (NAFLD) is common in obesity. However, weight reduction alone does not prevent the progression of NAFLD to end-stage disease associated with the development of cirrhosis and liver disease. In a previous experiment, 50% ethanol extract of Acanthopanax senticosus stem

BACKGROUND Syringin, also called eleutheroside B, is a main bioactive phenolic glycoside in Acanthopanax senticosus (Rupr. et Maxim.) Harms. Based on the "kidney dominates bone" theory of TCM, A. senticosus can strengthen bone and Syringin may be one of the responsibilities. OBJECTIVE The objectives

A new norlupane-triterpene, 3alpha,11alpha-dihydroxy-20,23-dioxo-30-norlupane-28-oic acid (1), and four known compounds; 3alpha,11alpha-dihydroxy-23-oxo-lup-20(29)-en-28-oic acid (2), 3alpha,11alpha-dihydroxylup-20(29)-en-28-oic acid (3), ent-kaur-16-en-19-oic acid (4), and betulabuside B (5) were

In the present study, the potential antioxidant and anti-inflammatory effects of Acanthopanax divaricatus vat. albeofructus (AE) and acanthoside-D (AD) isolated from AE against hepatic ischemia-reperfusion (I/R) injury were investigated in a rat model. Male Sprague-Dawley rats (200-220 g) were
