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...

BACKGROUND Alzheimer's disease is a neurodegenerative disease, characterized by progressive decline in memory and cognitive functions, that results from loss of neurons in the brain. Amyloid beta (Aβ) protein and oxidative stress are major contributors to Alzheimer's disease, therefore, protecting neuronal cells against Aβ-induced toxicity and oxidative stress might form an effective approach f...

1. Reference and definition The formulation of the “divided cell” algorithm as an approach to the study of the values of a function f (x, y) that is a product of two inhomogeneous linear forms on a lattice in R2 appears in E. S. Barnes, “The inhomogeneous minima of binary quadratic forms (IV)”, Acta Math. 92 (1954) 235–264. Although this is the fourth paper in a series, the first three were wri...
متن کاملSynthesis and antimicrobial activity of 4′,5,7-trihydroxy-3′- prenylflavanone
4′,5,7-Trihydroxy-3′-prenylflavanone was synthesized and tested for antibacterial effects against Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The synthesized compounds were characterized using UV, IR, MS and 1H and 13C NMR data. The antibacterial screening of the synthesized compounds were performed in vitro by the filter paper disc diffusion method.
