چکیده

We describe the synthesis of the N-(2-seleninatoethyl) amide of N-Boc-phenylalanine, serving here as a peptide model, and its reductive coupling reactions under mild conditions with unprotected thiouridine and glutathione. Selenosulfide products such as these comprise reversibly conjugated bio-components, and can potentially find uses as probes of biological function, such as enzyme inhibitors, delivery systems, or structural mimics.

تأثیر آمینواسیدهای استخراج شده از پودر خون و سولفات بر غنی‌سازی سلنیم، عملکرد و تندی پیاز

Selenium (Se) is known as an essential nutrient for human health. More than 15% of world population suffers Se deficiency mainly due to consumption of poor Se food crops. Bio fortification has been introduced as a sustainable and cost-effective approach to combat Se deficiency in the food chain. In this study the effect of selenite (SeO42-), sulphate, and certain amino acids on yield and bulb s...

Oxidation of Disulfides to Thiolsulfinates with Hydrogen Peroxide and a Cyclic Seleninate Ester Catalyst.

Cyclic seleninate esters function as mimetics of the antioxidant selenoenzyme glutathione peroxidase. They catalyze the reduction of harmful peroxides with thiols, which are converted to disulfides in the process. The possibility that the seleninate esters could also catalyze the further oxidation of disulfides to thiolsulfinates and other overoxidation products under these conditions was inves...

The modification in quality of parsley (Petroselinum crispum) by selenium and amino acids .

This research was conducted with the purpose of appraising the effect of Selenium (Se) and/or amino acid fertilizers (AA) on improving growth, physiology, and biofortification of parsley grown under high EC condition. Plants were foliarly supplemented with four levels of Se (0, 25, 50, 100 mgl-1) and/or two concentrations of AA (0 and 0.2%) three times with a week interval. The significantly in...

Synthesis of Naphthopyranopyrimidines Using Formic Acid as an Effective Catalyst under Solvent-free Conditions

An environmentally friendly, one-pot, three-component synthesis of 8,10-dimethyl-12-aryl-12H-naphtho[1′,2′:5,6]pyrano[2,3-d]pyrimidine-9,11-diones was achieved via coupling aromatic of aldehydes, β-naphthol and 6-amino-1,3-dimethyl uracil in the presence of formic acid as a catalyst under solvent-free conditions at 90 °C. This method has several advantages, such as efficiency, good yield, short...

A Thermodynamic Study on Nano-graphene Interaction with the Amino acid Phenylalanine in Acidic and Alkaline conditions at different temperatures

The project is comparing two types of calculation derived graphene. Which one of these carbon graphene linked to the phenylalanine amino acid from the acidic site (-COOH) and another from the base site (-NH2). For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then the calculation of the thermodynamic parameters performed on ...
