Synthesis of Some Nitrogen Functional Derivatives of 5-substituted-6-azauracil as Biologically Active Compounds
3-Arylhydrazono-2,4-dioxo-4-phenylbutanoates have been prepared by the coupling of benzoylpyruvate with aryldiazonium chlorides. Reactions of the 3-arylhydrazono-2,4- dioxo-4-phenylbutanoates with 1-aminoguanidine, semicarbazide, and thiosemicarbazide gave 5-substituted 2-imino-6-azauracil (3a), 6-azauracil (3b), and 2-thio-6-azauracil (3c), respectively. The analytical data of these compounds ...
متن کاملlichens on extensive green roofs : evapotranspiration , Cladonia
Green roofs are constructed ecosystems that provide ecosystem services in urban environments. Shallow substrate green roofs subject the vegetation layer to desiccation and other environmental extremes, so researchers have evaluated a variety of stress-tolerant vegetation types for green roof applications. Lichens can be found in most terrestrial habitats. They are able to survive extremely har...
متن کاملOligonucleotides and polynucleotides as biologically active compounds.
Nucleic acids are involved in the most important processes occurring in living cells and possess an enormous potential for specific interactions with different biopolymers. Specificity of recognition of DNA and RNA species by complementary nucleic acids is unique in the world of biopolymers. A great number of the proteins involved in processes of replication, transcription, and translation are ...
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...
Influence of Natural Sources of Biologically Active Substances on Livestock and Poultry Reproduction
Synthetic hormones and bioactive substances (vitamins, pigments and isoflavons) which have been used in the feed industry are accumulated in milk, meat and eggs. It is suspected that these are responsible for a number of side-effects such as carcinogenesis, liver and kidney damage, allergies in consumers. Furthermore the synthetic hormones, vitamins, pigments are less active than those extracte...
