In this study, types of the intermolecular interactions, interaction energies, void analysis diaquabis(3,4-dimethoxybenzoate)bis(nicotinamide)zinc(II) dihydrate (Complex 1), diaquabis(3,4-dimethoxybenzoate)bis(nicotinamide)nickel(II) 2), diaquabis(3,4-dimethoxybenzoate)bis(nicotinamide)cobalt(II) 3), whose crystal structures were characterized before, investigated with help CrystalExplorer prog...

METHODS Radiosensitisation with oxygen, carbogen or nicotinamide alone and oxygen or carbogen combined with nicotinamide was compared in early and late responding normal tissues in rodents. X-ray treatments were delivered as single doses or fractionated schedules of 2 fractions in 1 day, 2, 12 and 36 fractions in an overall time of 12 days and 10 fractions in 5 or 12 days. Acute skin reactions,...

Cefixime is a third-generation cephalosporin antibiotic with poor solubility and permeability. The aim was to compared between Dry Grinding (DG) Liquid-Assisted (LAG) methods formed cocrystal of cefixime nicotinamide. Cocrystal prepared in 1:1 molar ratio characterizated by differential scanning calorimetry (DSC), fourier transform infra-red (FTIR), electron microscopy (SEM), x-ray diffraction ...

Meat-eating was a game changer for human evolution. We suggest that the limiting factors for expanding brains earlier were scarcities of nicotinamide and tryptophan. In humans and some other omnivores, lack of meat causes these deficiencies. Nicotinamide adenine dinucleotide (NADH) is necessary to synthesize adenosine triphosphate (ATP) via either glycolysis or via the mitochondrial respiratory...

BACKGROUND Acne vulgaris is considered one of the most common disorders for which patients seek dermatologic care. In the current study, we evaluated efficacy of the 5% nicotinamide gel versus 2% clindamycin gel in the treatment of the mild-moderate acne vulgaris. MATERIALS AND METHODS This was a randomized, controlled clinical trial that was performed in 2009-2010. Sixty female patients with...

The eukaryotic nicotinamide riboside kinase (Nrk) pathway, which is induced in response to nerve damage and promotes replicative life span in yeast, converts nicotinamide riboside to nicotinamide adenine dinucleotide (NAD+) by phosphorylation and adenylylation. Crystal structures of human Nrk1 bound to nucleoside and nucleotide substrates and products revealed an enzyme structurally similar to ...

The growth inhibitory activity of 3-deazaguanosine toward a mutant line (TGR-3) of Chinese hamster ovary cells deficient in hypoxanthine-guanine phosphoribosyltransferase (EC 2.4.2.8) was substantially reversed by the simultaneous addition of nicotinamide riboside. The activities of most other ribonucleoside analogues tested were unaffected. The formation of cellular 3-deazaGMP and 3-deazaGTP f...

Compartmentalized redox faults are common to ageing diseases. Dietary constituents are catabolized to NAD(H) donating electrons producing proton-based bioenergy in coevolved, cross-species and cross-organ networks. Nicotinamide and NAD deficiency from poor diet or high expenditure causes pellagra, an ageing and dementing disorder with lost robustness to infection and stress. Nicotinamide and st...

The present study was conducted to investigate a new pathway for the degradation of nicotinamide adenine dinucleotide (NAD) by Penicillium brevicompactum NRC 829 extracts. Enzymes involved in the hydrolysis of NAD, i.e. alkaline phosphatase, aminohydrolase and glycohydrolase were determined. Alkaline phosphatase was found to catalyse the sequential hydrolysis of two phosphate moieties of NAD mo...

Molybdenum is absolutely required for the nitrate-reducing activity of the nicotinamide adenine dinucleotide nitrate reductase complex isolated from Chlorella fusca. The whole enzyme nicotinamide adenine dinucleotide nitrate reductase is formed by cells grown in the absence of added molybdate, but only its first activity (nicotinamide adenine dinucleotide diaphorase) is functional. The second a...
