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...

Some diazoacetyl derivatives of glycine known as antitumor and immunosuppressive agents have been found to be powerful mutagens of the base substitution type.
متن کاملProduction of a Permeability Defect in Escherichia Coli by the Mutagenic Alkylating Agent, Ethyl Sulfate.
During the course of our studies on the mechanism of action of the mutagen ethyl sulfate (Strauss and Okubo, 1960) we decided to test the effect of incubation in buffers of various composition after treatment with the mutagenic agent. It was found that incubation of treated cells in citrate had a lethal effect and it was decided to investigate the reason for this lethality. As a result of the i...
متن کاملdetection 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...
