Synthesis and anti-diabetic activity of new N,N-dimethylphenylenediamine-derivatized nitrilotriacetic acid vanadyl complexes.

Synthesis and anti-diabetic activity of new N,N-dimethylphenylenediamine-derivatized nitrilotriacetic acid vanadyl complexes. J Inorg Biochem. 2017 Jul 08;: Authors: Niu X, Yang J, Yang X Abstract Vanadium compounds are promising anti-diabetic agents. However, reducing the metal toxicity while keeping/improving the hypoglycemic effect is still a big challenge towards the success of anti-diabetic vanadium drugs. To improve the therapeutic potency using the anti-oxidative strategy, we synthesized new N,N-dimethylphenylenediamine (DMPD)-derivatized nitrilotriacetic acid vanadyl complexes ([VO(dmada)]). The in vitro biological evaluations revealed that the DMPD-derivatized complexes showed improved antioxidant capacity and lowered cytotoxicity on HK-2 cells than bis(maltolato)oxidovanadium (IV) (BMOV). In type II diabetic mice, [VO(p-dmada)] (0.15mmolkg(-1)/day) exhibited better hypoglycemic effects than BMOV especially on improving glucose tolerance and alleviating the hyperglycemia-induced liver damage. These insulin enhancement effects were associated with increased expression of peroxisome proliferator-activated receptor α and γ (PPARα/γ) in fat, activation of Akt (v-Akt murine thymoma viral oncogene)/PKB (protein kinase-B) in fat and liver, and inactivation of c-Jun NH2-terminal protein kinases (JNK) in liver. Moreover, [VO(p-dmada)] showed no tissue toxicity at the therapeutic dose in diabetic mice and the oral acute toxicity (L...

AbstractIntroductionInflammasome is a multi-protein complex which is an important constituent of innate immunity. It mainly consists of three parts, apoptosis-associated speck-like protein containing caspase recruitment domain (ASC), caspase protease, and a NOD-like receptor (NLR) family protein (such as NLRP1) or an HIN200 family protein (such as AIM2). Inflammasome is widely studied in many autoimmune diseases and chronic inflammatory reactions, such as familial periodic autoinflammatory response, type 2 diabetes, Alzheimer's disease, and atherosclerosis. Activation of inflammasome in the kidney has been widely reported ...

Basel, 22 May 2020 - Roche (SIX: RO, ROG; OTCQX: RHHBY) will present new pooled pivotal satralizumab safety results for the treatment of neuromyelitis optica spectrum disorder (NMOSD), a rare, debilitating central nervous system disorder. These data are being presented at the 6th Annual Meeting of the European Academy of Neurology (EAN) and show satralizumab was well-tolerated in a broad patient population – including adolescents, for whom there is no approved medicine. Satralizumab is an investigational humanised monoclonal antibody that targets the interleukin-6 (IL-6) receptor, believed to play a key role in the i...

Giustino Orlando Claudio Ferrante Anacamptis pyramidalis (L.) Rich. forms part of the Orchidaceae family that is highlyvalued for its horticultural as well as therapeutic benefits. The present study set out to investigatethe inhibitory activity of A. pyramidalis tubers against key biological targets for the management oftype 2 diabetes, Alzheimer disease, and skin hyperpigmentation. In addition, the antioxidantpotential of the extracts was also assessed using multiple methods. The detailed phytochemicalprofiles of the extracts were determined using high‐performance liquid chromatography. Based onqualitative phyto...

A, Lima LM Abstract A sedentary life-style is a significant public health issue. It increases the incidence of type-2 diabetes mellitus (DM2) and systemic arterial hypertension (SAH), which in turn may impair physical and mental health. In fact, disrupted glucose metabolism is one of the characteristics of Alzheimer's dementia, and it is often dubbed as type-3 diabetes. The purpose of this crosssectional study was to assess the level of activity, body composition, cardio-vascular risk and cognitive profile of patients with DM2 and/or SAH. Various parameters were evaluated, such as anthropo-metric variables, pedo-...

Abstract BACKGROUND: β-Site APP-cleaving enzyme 1 (BACE1) is a key enzyme involved in the pathophysiology of Type 2 diabetes mellitus (T2DM) and mild cognitive impairment (MCI). We aimed to investigate the potential associations of plasma BACE1 levels and BACE1 gene polymorphism with different cognitive performances in T2DM patients with MCI. METHODS: The recruited 186 T2DM subjects were divided into 92 MCI group and 94 healthy-cognition controls, according to the Montreal Cognitive Assessment (MoCA) scores. Sociodemographic characteristics, clinical parameters and neuropsychological tests were assessed....

CONCLUSION: Research has shown that insulin insensitivity in T2DM leads to neurodegeneration through mechanisms involving a variety of extracellular, membrane receptor, and intracellular signaling pathway disruptions. Some therapeutics, such as intranasal administration of insulin and neuroactive substances have shown promise but face problems related to genetic background, accessibility to the brain, and invasiveness of the procedures.

AbstractAims/hypothesisMendelian randomisation studies have not shown a clear causal effect of high plasma glucose on the risk of Alzheimer ’s disease. We tested the hypothesis that high plasma glucose caused by genetic variation has a causal effect on the risk of unspecified dementia, Alzheimer’s disease and vascular dementia in the general population.MethodsA Mendelian randomisation design was used with data from 115,875 individuals from the Copenhagen General Population Study and the Copenhagen City Heart Study. Findings for Alzheimer ’s disease were validated in a two-sample Mendelian design with 455,...
