ANTI-TUMOR ACTIVITY OF SOME NATURAL COMPOUNDS

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...

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...

Antibacterial Activity of Some New Azole Compounds

Tumor initiatory activity of some chloromononitrobenzenes and other compounds.

Treatment of mouse skin with pentachloronitrobenzene and each of the 3 tetrachloronitrobenzenes resulted in multiple papilloma formation during subsequent treatment with croton oil. The highest yield of papillomas was obtained with 2,3,4,5-tetrachloronitrobenzene, the only compound of the 4 that has a stable nitro group and does not give rise to appreciable mercapturic acid in the rabbit. It is...

Exogenous natural glycoprotein multiple mechanisms of anti-tumor activity.

Natural glycoproteins can induce apoptosis of tumor cells and exert anti-tumor activity by immunomodulatory functions, cytotoxic and anti-inflammation effects, and inhibition of endothelial growth factor. Given their prospects as novel agents, sources of natural antitumor glycoproteins have attracted attention and new research directions in glycoprotein biology are gradually shifting to the dir...
