Alzheimer's disease (AD) is an age-related neurodegenerative disorder characterized by memory deficits and cognitive decline. Excessive amyloid-β (Aβ) peptide aggregates and forms soluble oligomers and insoluble cerebral amyloid plaques, which is widely thought to be the underlying pathogenic mechanism of AD. Therefore, effective regulation of Aβ metabolism is an important aspect of preventing and improving AD. Berberine, which is the main active component of the traditional medicinal herb Coptidis rhizoma, has a positive effect on reducing Aβ levels...

Practitioners of traditional Chinese medicine (TCM) commonly prescribe medicinal formulations relying on the purported synergism of a combination of plant species, sometimes incorporating animal parts and minerals. Bear bile, obtained from either wild or farmed bears, is a commonly used constituent of traditional medicine formulations. With several bear species now listed under Convention on International Trade in Endangered Species of Wild Fauna and Flora as threatened with extinction and with bear farming being actively campaigned against on ethical grounds, it is important to seek and promote alternatives to the use of bear bile as medicine...

BACKGROUND: Due to increasing antimicrobial resistance, a bismuth-based quadruple regimen has been recommended as an alternative first-line therapy for Helicobacter pylori (H pylori) eradication. However, different results are varied greatly and the availability of bismuth was limited in some countries. We assessed the efficacy and safety of 14-day berberine-containing quadruple therapy as an alternative regimen for H pylori eradication. METHODS: In a randomized, open-label, non-inferiority, phase IV trial between November 25, 2014, and October 15, 2015, 612 treatment-naive patients were randomly assigned to 14-day berberine-containing (n = 308) or 14-day bismuth-containing (n = 304) quadruple therapy...

Quercetin, naringenin, and berberine are plant bioactives that can cross the blood-brain barrier and offer neuroprotection. In the present study, we looked into the effect of them on expression of various glucose transporters and key components of brain insulin signalling, namely, insulin receptor substrate 1 (IRS 1), phosphatidyl inositol 3 kinase (PI3K), Akt 1 and low-density lipoprotein receptor-related protein 1 (LRP1) in brain of control, diabetic and bioactive-treated rats by Western blot. Amongst the bioactives tested, quercetin was more potent and restored LRP1 and brain insulin signalling components as well as glucose transporters such as GLUTs 1, 2, 3 and 4 in diabetic animals...

The association between diabetes and dementia has been well-demonstrated by epidemiologic studies. Berberine (BBR) has been reported to ameliorate diabetes and diabetic encephalopathy (DE). However, the mechanism is still unknown. In this study, we employ a diabetic model, db/db mice, to explore whether BBR could protect DE through SIRT1/endoplasmic reticulum (ER) stress pathway. The behavioral results (Morris water maze, Y-maze spontaneous alternation test and fearing condition test) showed that oral administration of BBR (50 mg/kg) improved the learning and memory ability...

Low-density lipoprotein cholesterol (LDL-C) reduction is associated with a significant decrease in mortality, and statins represent the most effective drugs to achieve this. However, side effects of statins are very common and may lead to treatment discontinuation. Nutraceuticals are a combination of natural components that have shown efficacy in lowering LDL-C concentration when used alone or in association with other agents in patients who are intolerant to high-dose statins. Our aim was to compare the efficacy and tolerability of low-dose statin (LDS) therapy versus combined therapy of LDS plus a nutraceutical combination containing red yeast rice, policosanol, berberine, folic acid, coenzyme Q10 and astaxanthin (Armolipid Plus) in high-risk patients...

Riemerella anatipestifer, an important infectious bacterium affecting the duck industry, has 5-75% mortality, depending on strain virulence. We previously demonstrated that proinflammatory cytokines are involved in inflammation during, and regulating susceptibility to, R. anatipestifer infection. We investigated the effects of the anti-inflammatory compound berberine in duck splenic lymphocytes stimulated with killed R. anatipestifer, and in R. anatipestifer-infected ducks. IL-17A, IL-17F, and IL-1β transcripts were downregulated, and IFN-γ and IL-10 transcripts enhanced, in berberine-treated stimulated splenic lymphocytes, compared to stimulated untreated splenic lymphocytes...

Berberine (BBR) is a natural isoquinoline alkaloid with very impressive health benefits. It is one of the most effective natural supplements available; however, its ameliorative mechanism against methotrexate (MTX)-induced liver injury is not well defined. This study investigated the protective effect of BBR against MTX hepatotoxicity, focusing on its ability to attenuate oxidative stress and apoptosis and to activate nuclear factor (erythroid-derived 2)-like 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling and peroxisome proliferator activated receptor gamma (PPARγ)...

The human ether-a-go-go-related gene (hERG) potassium channel conducts rapid delayed rectifier potassium currents (IKr) and contributes to phase III cardiac action potential repolarization. Drugs inhibit hERG channels by binding to aromatic residues in hERG helixes. Berberine (BBR) has multiple actions, and its hydrogenated derivative dihydroberberine (DHB) is a potential candidate for developing new drugs. Previous studies have demonstrated that BBR blocks hERG channels and prolongs action potential duration (APD)...

Doxorubicin (DOX) is one of the most widely used anti-neoplastic agents. However, treatment with DOX is associated with cumulative cardiotoxicity inducing progressive cardiomyocyte death. Sirtuin 3 (Sirt3), a mitochondrial deacetylase, regulates the activity of proteins involved in apoptosis, autophagy and metabolism. Our hypothesis is that pharmacological modulation by berberine (BER) pre-conditioning of Sirt3 protein levels decreases DOX-induced cardiotoxicity. Our results showed that DOX induces cell death in all experimental groups...
