Synthesis,Characterization, Biological Evaluation and anti corrosion activity of some new bis-piperidone Derivatives
Journal Title: International journal of Advanced Biological and Biomedical Research - Year 2013, Vol 1, Issue 2
Abstract
Aseries of piperidine derivatives was synthesis by the reaction between substituted benzaldhyde ,pentanone-3,and ammonium acetate by refluxining for 1-2 hr in ethanol and the derivatives refluxed with (4,4'-Diaminodiphenyl sulphone) yielded bispiperidine ,the structures of the synthesized compounds were confirmed by spectroscopy analysis , The reported compounds were screened for their antibacterial activities against : Staphylococcus aureus, Klebsiella,Escherichia coli,pseudomonas aeruginosa,Salmonilla typhi, Enterobacter. The synthesized piperidone-4 were tested to determine their ability to inhibit corrosion of mild steel in 1mol.L-1 H2SO4 and measured by polarization measurements . Which showed that these compounds act as mixed-type inhibitors. The studies revealed that the nitrogen of Schiff base and sulfur atome ,piperidine moiety ,and the phenyl ring assist largely in corrosion control.

Shifting mosaics in semi-steppe rangelands driven by interactive effect of human made disturbances
Semi-steppe rangelands are a complex, highly dynamic and often multi-layered mosaic of grassland, shrubland, and intermediate communities. A few recent studies have explicitly or implicitly developed synthetic hypothes...
