BACKGROUND Berberine is an active compound in Coptidis Rhizoma (Huanglian) with multiple pharmacological activities including antimicrobial, antiviral, anti-inflammatory, cholesterol-lowering and anticancer effects. The present study aims to determine the hepatoprotective effects of berberine on serum and tissue superoxide dismutase (SOD) levels, the histology in tetrachloride (CCl4)-induced li...
BACKGROUND/AIMS Berberine, a naturally occurring isoquinoline alkaloid, acts against oxidative stress (OS) and endoplasmic reticulum stress (ERS), both of which are responsible for Aldosterone (Aldo) -induced podocyte injury. However, the direct effects of berberine on Aldo-induced OS, ERS, and podocyte injury are not well defined. METHODS Uninephrectomized Sprague-Dawley rats were given 1% N...
Berberine is an isoquinoline alkaloid, occurring in nature as the main constituent of several plants with medicinal use in kidney stone disease. This work was undertaken to evaluate its antiurolithic potential and explore the possible underlying mechanism(s). Berberine was tested in vitro for the antioxidant effect and in vivo for diuretic and antiurolithic effects on an animal model of calcium...
Alkaloids comprise one of the largest groups of plant secondary metabolites. Berberine, a benzylisoquinoline alkaloid, is preferentially accumulated in the rhizome of Coptis japonica, a ranunculaceous plant, whereas gene expression for berberine biosynthetic enzymes has been observed specifically in root tissues, which suggests that berberine synthesized in the root is transported to the rhizom...
Rapamycin is clinically used as an immunosuppressant. Increasing evidence suggests that rapamycin has an important inhibitory role in the development and progression of different types of cancer and that it is a promising candidate for cancer chemotherapy. Berberine is an isoquinoline alkaloid isolated from medicinal plant species, which has been used in traditional Chinese medicine with no sig...
The cytotoxicity of berberine on C6 rat glioma cells indicated that berberine induced morphological changes and caused cell death through G2/M arrest and apoptosis. While undergoing apoptosis, there was a remarkable accumulation of G2/M cells with the upregulatoin of Wee1 but it also inhibited cyclin B, CDK1 and Cdc25c that led to G2/M arrest. Along with cytotoxicity in C6 cells, several apopto...
Berberine (B1), isolated from stems of Coscinium fenestratum (Goetgh.) Colebr, was used as a principle structure to synthesize three phenolic derivatives: berberrubine (B2) with a single phenolic group, berberrubine chloride (B3) as a chloride counter ion derivative, and 2,3,9,10-tetra-hydroxyberberine chloride (B4) with four phenolic groups, to investigate their direct and indirect antioxidant...
Mouse peritoneal mast cells (PMC) express a connective tissue-type mast cell (CTMC) phenotype, including reactivity with the heparin-binding fluorescent dye berberine sulfate and incorporation of [35S] sulfate predominantly into heparin proteoglycans. When PMC purified to greater than 99% purity were cultured in methylcellulose with IL-3 and IL-4, approximately 25% of the PMC formed colonies, a...
Berberine is a quaternary ammonium salt from the protoberberine group of isoquinoline alkaloids found in such plants as gender Berberis. Berberine is recognised to improve glucose and lipid metabolism disorders and preliminary clinical evidences suggest the ability of berberine to reduce endothelial inflammation improving vascular health, even in patients already affected by cardiovascular dise...
The present study was carried out to determine the effect of berberine on glucose homeostasis and several biomarkers associated with insulin sensitivity in male Wistar rats with intraperitoneal injection of streptozotocin (STZ)-induced diabetes. Rats with fasting blood glucose 16.7 mmol/L after 2 weeks of STZ injection were divided into two groups. One group was used as the diabetic control and...
