Synthesis and Structure-Activity Relationships of 7α-Alkylthioandrostanes

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...

Synthesis and structure-activity relationships of amides of amphotericin B.

A series of aliphatic amides of amphotericin B have been synthesized. The structure of the derivatives which were obtained has been established by mass spectrometry. Their biological properties: inhibition of growth of Saccharomyces cerevisiae and hemolytic activity have been determined. The quantitative relationships between the activity of amides of amphotericin B against S. cerevisiae and th...

Isolation Synthesis, and Structure – Activity Relationships of Antioxidants of Yeasts

Synthesis, antiproliferative evaluation, and structure-activity relationships of 3-arylquinolines.

Synthesis and structure-activity relationships of fenbufen amide analogs.

The previous discoveries of butyl fenbufen amide analogs with antitumor effects were further examined. The amide analogs with 1, 3, 4 and 8 carbons chains were prepared in 70-80% yield. Fenbufen had no cytotoxic effects at concentrations ranging from 10 to 100 μM. Methyl fenbufen amide had significant cytotoxic effects at a concentration of 100 μM. As the length of the alkyl amide side chain in...
