The arachidonic acid pathway consists of several enzymes and targeting them is favored for developing anti-inflammatory drugs. However, till date the current drugs are generally active against a single target, leading to undesirable side-effects. Phytochemicals are known to inhibit multiple targets simultaneously and hence, an attempt is made here to investigate their suitability. A pharmacophore based study is performed with three sets of reported phytochemicals namely, dual 5-LOX/mPGES1, alkaloids and FLAP inhibitors...

In this study, we explored the effect of berberine treatment on the AGEs-RAGE pathway in a rat model of diabetic nephropathy, and we investigated the mechanism by which key factors caused kidney injury and the effects of berberine. In vivo, berberine improved fasting blood glucose, body weight, the majority of biochemical and renal function parameters and histopathological changes in the diabetic kidney. Western blotting and immunohistochemistry revealed significant increases in the levels of AGEs, RAGE, P-PKC-β and TGF-β1 in injured kidneys, and these levels were markedly decreased by treatment with berberine...

The current study was designed to investigate the therapeutic potential of berberine on monosodium urate (MSU) crystal stimulated RAW 264.7 macrophages and in MSU crystal induced rats. Our results indicate that berberine (25, 50 and 75μM) suppressed the levels of pro-inflammatory cytokines (interleukin-1beta (IL-1β) and tumor necrosis factor alpha (TNFα)) and intracellular reactive oxygen species in MSU crystal stimulated RAW 264.7 macrophages. The mRNA expression levels of IL-1β, caspase 1, nucleotide-binding oligomerization domain-like receptor pyrin domain containing 3 (NLRP3), thioredoxin interacting protein (TXNIP) and kelch-like ECH-associated protein 1 (Keap1) were found downregulated with the upregulation of nuclear factor erythroid-2-related factor 2 (Nrf2) transcription factor and its associated anti-oxidant enzymes: Heme oxygenase I (HO-1), superoxide dismutase (SOD1), glutathione peroxidase (GPx), NADPH quinone oxidoreductase-1 (NQO1) and catalase (CAT) in MSU crystal stimulated RAW 264...

Inflammation is a known mediator of adverse ventricular remodeling after myocardial infarction (MI) that may lead to reduction of ejection fraction and subsequent heart failure. Berberine is a isoquinoline quarternary alkaloid from plants that has been associated with anti-inflammatory, anti-oxidative, and cardioprotective properties. Its poor solubility in aqueous buffers and its short half-life in the circulation upon injection, however, have been hampering the extensive usage of this natural product. We hypothesized that encapsulation of berberine into long circulating liposomes could improve its therapeutic availability and efficacy by protecting cardiac function against MI in vivo...

Status epilepticus (SE) is a life-threatening neurologic condition, instigating epileptogenesis to transform normal brain to an epileptic condition. SE is followed by spontaneous recurrent seizures (SRS) and final development of temporal lobe epilepsy (TLE) that is resistant to treatment. Neuroprotective strategies are increasingly put forward as a promising therapy to prevent and/or manage epileptic conditions. In this study, we investigated whether berberis alkaloid, i.e. berberine (BBR), could ameliorate intrahippocampal kainate-induced SE and its consequent epileptogenic process and to explore some underlying mechanisms...

BACKGROUND: Berberis aristata, because of its berberine content, and Monascus purpureus fermented rice, because of the presence of monacolins (naturally derived statins), are widely investigated food-grade ingredients used to formulate cholesterol-lowering supplements. Although they are extensively used, berberine is poorly absorbed and monacolins are poorly chemically characterized, not standardized, and possibly contaminated with toxic compounds. Silymarin is reported to enhance berberine absorption, while Monakopure™-K20 (MK-20) is a highly standardized red yeast rice containing monacolins K and KA in the ratio of 1:1 but not secondary monacolins, dehydromonacolins, or citrinin...

Berberrubine (BRB) is the primary metabolite of berberine (BBR) that has shown a stronger glucose-lowering effect than BBR in vivo. On the other hand, BRB is quickly and extensively metabolized into berberrubine-9-O-β-D-glucuronide (BRBG) in rats after oral administration. In this study we compared the pharmacokinetic properties of BRB and BRBG in rats, and explored the mechanisms underlying their glucose-lowering activities. C57BL/6 mice with HFD-induced hyperglycemia were administered BRB (50 mg·kg(-1)·d(-1), ig) for 6 weeks, which caused greater reduction in the plasma glucose levels than those caused by BBR (120 mg·kg(-1)·d(-1)) or BRB (25 mg·kg(-1)·d(-1))...

Emerging evidence has shown that berberine has a protective effect against metabolic syndrome such as obesity and type II diabetes mellitus by activating AMP-activated protein kinase (AMPK). AMPK induces CD36 trafficking to the sarcolemma for fatty acid uptake and oxidation in contracting muscle. However, little is known about the effects of AMPK on CD36 regulation in the liver. We investigated whether AMPK activation by berberine affects CD36 expression and fatty acid uptake in hepatocytes and whether it is linked to hepatic lipid accumulation...

Alzheimer's disease (AD) is the most common age-related neurodegenerative disease and is characterized by the production of β-amyloid (Aβ) proteins and progressive loss neurons. Berberine, an isoquinoline alkaloid isolated and extracted from Coptidis and rhizome and Cortex phellodendri, has a wide range of pharmacological effects. Here, we examined the neuroprotective effects of Berberine against neuronal insults induced by Aβ25-35 in primary cultured hippocampal neurons. Exposure of these neurons to the Aβ25-35 protein significantly increased cell viability loss and apoptosis...

Berberine (BBR), one of the main bioactive compounds in Rhizoma coptidis, has multiple pharmacological activities. It has been reported that 8-cetylberberine (8-BBR-C16) has increased anti-microbial property in vivo and a higher bioavailability in hamsters. Therefore, in the present study, we used apolipoprotein E-deficient mice (ApoE(-/-)) as an atherosclerosis model to investigate the anti-atherosclerosis effects of 8-BBR-C16. After 12weeks of treatment, the atherosclerotic plaque area of the aorta, serum lipid profile, the plasma redox state and the expression of inflammatory cytokines in ApoE(-/-) mice were determined...

Osteosarcoma is one of the most devastating cancers with associated poor prognosis. Chronic bone inflammation frequently predisposes to tumorigenesis and progression of osteosarcoma. In the tumor inflammatory microenvironment, caspase-1 and its processed cytokines such as interleukin 1β (IL-1β) play an important role in the occurrence and development of cancer. Berberine is an isoquinoline alkaloid extracted from the dry root of Coptidis Rhizoma, which has been found to exhibit significant anticancer effects on a wide spectrum of carcinomas including osteosarcoma...
