Synthesis and antimicrobial evaluation of 6-azauracil non-nucleosides
摘要:
The present study describes synthesis and antimicrobial evaluation of a series of novel 6-azauracil non-nucleosides. Reaction of silylated 6-azauracils with the appropriate chloroethers gave the corresponding non-nucleosides. 1-(Allyloxymethy)6-azauracils and non-nucleosides bearing indanyl, cyclohexenyl, and cyclohexyl moieties were obtained via silylation of 6-azauracils followed by treatment with the appropriate acetals. Selected compounds were tested for their in vitro antimicrobial activity against a panel of standard strains of Gram-positive and Gram-negative bacteria and the yeast-like pathogenic fungus Candida albicans. Four compounds showed marked inhibitory activity particularly against the tested Gram-positive bacteria.

Complexes of lanthanide chlorides with pyruvic acid semicarbazone (PASH), having the general formula Ln(PAS) 3 . nH2O (where Ln = La-Nd, Sm-Dy, Er, Yb; n = 1-3), have been synthesized and characterized on the basis of elemental analyses, IR spectra and thermal analyses. It has been found that the ligand and its complexes possess scavenger effects on OH. and O2-. radicals.
