Comparison of Inhibitory Activities of meta and para Substituted N-aryl 3-Hydroxypyridin-4-one Mannosides Towards Type 1 Fimbriated E. coli
In uropathogenic Escherichia coli, mannose-specific adhesion is mediated by the FimH adhesin located at the tip of type 1 fimbriae. Novel mannosylated N-aryl substituted 3-hydroxypyridin-4ones with meta substituents on the aryl part of the molecule were prepared, and their inhibitory properties towards the adhesion of E. coli to guinea pig erythrocytes explored using the hemagglutination assay....

Pathogenic infections and inflammation are very common ailments humans suffer. Upsurge of resistant pathogens has impeded the antimicrobial drug development process in recent years and the search of new antimicrobial agents is clearly evident from the literature. In line with these developments the synthesis of N-substituted aryl-2-({4-[(substituted aryl carbamoyl) methyl]-5-(pyridin-4-yl)-4H-1...

متن کاملEvaluation of Liver Toxicity of 2-Methyl-3-Hydroxypyridin-4-one in Iron Overloaded Rats
Hydroxypyridinone iron chelators are currently the main candidates for development of orally active iron chelating alternatives to desferrioxamine (DFO). In the present study, the relative efficacy and liver toxicity of a bidentate chelator, 2-methyl-3-hydroxypyridin-4-one (MHPO), was studied in iron overloaded rats and compared with those of DFO. For iron overloading, rats received i.p. ...
