INTRODUCTION: Dimethyl fumarate (DMF) is a novel oral therapy used for the treatment of relapse-remitting multiple sclerosis (RRMS). In two 2-year pivotal Phase 3 trials in patients with RRMS, DMF significantly reduced disease activity based on both clinical and magnetic resonance imaging (MRI) findings and demonstrated an acceptable safety profile. However, there is currently a lack of comparative data which explore the relationship between work productivity and health-related quality of life (HRQoL) outcomes in RRMS and how these differ among RRMS therapies, including DMF...

INTRODUCTION: Annonaceous acetogenins (AAGs) constitute a group of environmental neurotoxins, possibly implicated in sporadic atypical Parkinsonism/dementia complexes. The recent evidencing of complex mixtures of AAGs in edible fruits and derived food products requires efficient and practical analytical tools for an estimation of human exposure. OBJECTIVE: To develop a simple method for the direct quantitation of the majority of AAGs (sub-types 1a and 1b) within crude extracts, using commonly available (1) H-NMR spectrometers, for food control...

The transcription factor NRF2 (NFE2L2), regulates important antioxidant and cytoprotective genes. It enhances cancer cell proliferation and promotes chemoresistance in several cancers. Dimethyl fumarate (DMF) is known to promote NRF2 activity in non-cancer models. We combined in vitro and in vivo methods to examine the effect of DMF on cancer cell death and the activation of the NRF2 antioxidant pathway. We demonstrated that at lower concentrations (< 25 μM), DMF has a cytoprotective role through activation of the NRF2 antioxidant pathway...

Multiple Sclerosis (MS) is a neurological condition driven in part by immune cells from the peripheral circulation, the targets for current successful therapies. The autoimmune and MS risk gene ZMIZ1 is underexpressed in blood in people with MS. We show that, from three independent sets of transcriptomic data, expression of ZMIZ1 is tightly correlated with that of hundreds of other genes. Further we show expression is partially heritable (heritability 0.26), relatively stable over time, predominantly in plasmacytoid dendritic cells and non-classical monocytes, and that levels of ZMIZ1 protein expression are reduced in MS...

BACKGROUND AND PURPOSE: Quantitative MR imaging parameters help to evaluate disease progression in multiple sclerosis and increase correlation with clinical disability. We therefore hypothesized that T1 values might be a marker for ongoing tissue damage or even remyelination and may help increase clinical correlation. MATERIALS AND METHODS: MR imaging was performed in 17 patients with relapsing-remitting MS at baseline and after 12 months of starting immunotherapy with dimethyl fumarate...

AIM: Oxidative stress plays a key role in Parkinson's disease (PD) and nuclear transcription factor related to NF-E2 (Nrf-2) is involved in neuroprotection against PD. The aim of the present study was to investigate the neurotherapeutic action, NF-κB/Nrf-2 dependent, of DMF in a mouse model of PD and in vitro SHSY-5Y cells. RESULTS: Daily oral gavage of DMF (10, 30 and 100 mg/kg) significantly reduced neuronal degeneration of dopaminergic tract and behavioral impairments induced by four injections of the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)...

Background: The Explorys Enterprise Performance Management (EPM) database contains de-identified clinical data for 50 million patients. Multiple sclerosis (MS) disease-modifying therapies (DMTs), specifically interferon beta (IFNβ) treatments, may potentiate depression. Conflicting data have emerged, and a large-scale claims-based study by Patten et al. did not support such an association. This study compares the results of Patten et al. with those using the EPM database. Methods: "Power searches" were built to test the relationship between antidepressant drug use and DMT in the MS population...

Dimethyl fumarate (DMF) is an approved drug for the management of relapsing multiple sclerosis. Despite efficacy, DMF is also reported to be a challenging drug owing to concerns like gastrointestinal tract flushing, multiple dosing, lower brain permeability, less patient compliance, and economic hurdles. The present study aims to develop DMF-tocopherol acetate nanolipidic carrier (NLCs) to enhance brain permeability and improve the gastric tolerance. The developed DMF-tocopherol acetate NLCs offered an average size of 69...

The therapeutic mode of action of dimethyl fumarate (DMF), approved for treating patients with relapsing-remitting multiple sclerosis, is not fully understood. Recently, we and others demonstrated that Ab-independent functions of distinct B cell subsets are important in mediating multiple sclerosis (MS) relapsing disease activity. Our objective was to test whether and how DMF influences both the phenotype and functional responses of disease-implicated B cell subsets in patients with MS. High-quality PBMC were obtained from relapsing-remitting MS patients prior to and serially after initiation of DMF treatment...

A novel strictly anaerobic, thermotolerant, moderately halophilic, organotrophic bacterium, strain MRo-4T, was isolated from the sample of a microbial mat, developed under the flow of subsurface water in TauTona gold mine, South Africa. Cells of the novel isolate stained Gram-positive and were motile spore-forming rods, 0.2-0.3 µm in width and 5-20 µm in length. Strain MRo-4T grew at 25 - 50°C, pH 7.0 - 8.8, and at NaCl concentration from 5 to 100 g l-1. The isolate was able to ferment yeast extract, peptone and mono-, oligo- and polysaccharides, including cellulose and chitin...

Electrophilic small molecules are an important class of chemical probes and drugs that produce biological effects by irreversibly modifying proteins. Examples of electrophilic drugs include covalent kinase inhibitors that are used to treat cancer and the multiple sclerosis drug dimethyl fumarate. Optimized covalent drugs typically inactivate their protein targets rapidly in cells, but ensuing time-dependent, off-target protein modification can erode selectivity and diminish the utility of reactive small molecules as chemical probes and therapeutics...

Dimethyl fumarate (DMF), fingolimod, and teriflunomide are oral disease-modifying therapies (DMTs) indicated for the treatment of relapsing-remitting multiple sclerosis. Despite well-established limitations of cross-trial comparisons, DMTs are still frequently compared in terms of relative reductions in specific endpoints, most commonly annualized relapse rate. Consideration of absolute risk reduction and number needed to treat (NNT) provides an alternative approach to assess the magnitude of treatment effect and can provide valuable additional information on therapeutic gain...

REVIEW
P Soelberg Sorensen
Currently, more than ten drugs have been approved for treatment of relapsing-remitting multiple sclerosis (MS). Newer treatments may be more effective, but have less favorable safety record. Interferon-β preparations and glatiramer acetate treatment require frequent subcutaneous or intramuscular injections and are only moderately effective, but have very rarely life-threatening adverse effects, whereas teriflunomide and dimethyl fumarate are administered orally and have equal or better efficacy, but have more potentially severe adverse effects...

Spinal cord injury (SCI) causes permanent changes in motor, sensory and autonomic functions. Unfortunately, there are not a stable cures and current treatments include surgical decompression, methylprednisolone and hemodynamic control that lead to modest function recovery. Fumaric acid esters (FAEs) were firstly used in the management of an immunological skin disorder, such as psoriasis. Because of their potent anti-inflammatory effects, they have been introduced in multiple sclerosis. Investigation shown not only anti-inflammatory, but also supposed neuroprotective mechanism of action...
