Innovative Preparation of Biopharmaceuticals Using Transglycosylation Activity of Microbial Endoglycosidases

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Contribution Synthesis of Bioactive Glycoconjugates Using the Transglycosylation Activity of Microbial Endoglycosidase

Glycoconjugates such as glycoproteins and glycolipids have structures in which proteins or lipids are conjugated with oligosaccharide moieties, and are essential components of biological organisms, including various organs of animals, tissues of plants, and cell walls and membranes of microorganisms. However, the exact roles of these glycoconjugates were not clearly understood until recently. T...

Synthesis of Bioactive Glycoconjugates Using the Transglycosylation Activity of Microbial Endoglycosidase

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
