Solution behaviour of PUs of different composition in DMF, LiBr/DMF, and THF was studied by a static light scattering (LS), size exclusion chromatography coupled to a multi-angle light scattering (SEC-MALS), and viscometry. The influence of PU chemical composition, kind of a solvent, and addition of simple salts on PU hydrodynamic volume was investigated. The values of the second virial coeffic...

OBJECTIVE To examine the mechanism underlying the preferential CD8+ vs CD4+ T-cell lymphopenia induced by dimethyl fumarate (DMF) treatment of MS. METHODS Total lymphocyte counts and comprehensive T-cell subset analyses were performed in high-quality samples obtained from patients with MS prior to and serially following DMF treatment initiation. Random coefficient mixed-effects analysis was u...

Acute or long-term exposure to N,N-dimethylformamide (DMF) can induce abnormal liver function. It is well known that DMF is mainly metabolized in the liver and thereby produces reactive oxygen species (ROS). The base excision repair (BER) pathway is regarded as a very important pathway involved in repairing ROS-induced DNA damage. Several studies have explored the associations between GSTM1, GS...

Dimethylfumarate (DMF) inhibits signals transmitted by Rel proteins and is used for the treatment of inflammatory skin diseases such as psoriasis, but potential effects of DMF on tumor progression have yet not been analyzed. We show that DMF reduced melanoma growth and metastasis in severe combined immunodeficient mouse models. To identify targets of DMF action, we analyzed mRNA expression in D...

Delayed-release dimethyl fumarate (DMF), also known as gastroresistant DMF, is the most recently approved oral disease-modifying treatment (DMT) for relapsing multiple sclerosis. Two randomized clinical trials (Determination of the Efficacy and Safety of Oral Fumarate in Relapsing-Remitting MS [DEFINE] and Comparator and an Oral Fumarate in Relapsing-Remitting Multiple Sclerosis [CONFIRM]) demo...

The effect of delayed-release dimethyl fumarate (DMF; also known as gastro-resistant DMF) on the Multiple Sclerosis Functional Composite (MSFC) was assessed using integrated Phase 3 DEFINE and CONFIRM data. Patients treated with DMF (n = 769) demonstrated significant superiority on the MSFC, and each component, compared with placebo (n = 771) over two years: mean change for DMF vs placebo was 0...

To date, DMF has been considered as the only solvent suitable for peptide synthesis. Here we demonstrate the capacity of THF and ACN, which are friendlier solvents than DMF, to yield the product in higher purity than DMF. Using various peptide models, both THF and ACN reduced racemization in solution-phase and solid-phase synthesis when compared with DMF. Moreover, the use of ACN and THF in the...

Cigarette smoking is a major risk factor in lung carcinogenesis via carcinogens such as polycyclic aromatic hydrocarbons (PAHs) and nitrosamines. In this study, we used benzo[a]pyrene (BaP) as the classic PAH compound and BEAS-2B cells, a model of normal human bronchial epithelial cells, to investigate whether 5,7-dimethoxyflavone (5,7-DMF) and 3',4'-DMF compared with resveratrol (RV) have chem...

Background Diffuse myocardial fibrosis (DMF) is an important factor in cardiac disease, but until recently could only be accurately assessed with biopsy. We hypothesised that DMF measured by Equilibrium contrast CMR (EQ-CMR) is elevated in cardiac pressure overload (hypertension and aortic stenosis), that the degree of DMF will track the clinical severity of pressure overload and cardiac effect...

Delayed-release dimethyl fumarate (also known as gastro-resistant dimethyl fumarate), an oral therapeutic containing dimethyl fumarate (DMF) as the active ingredient, is currently approved for the treatment of relapsing multiple sclerosis. DMF is also a component in a distinct mixture product with 3 different salts of monoethyl fumarate (MEF), which is marketed for the treatment of psoriasis. P...
