Isoxazole Derivatives

A sequence of new isoxazole substituted Schiff base and Mannich base of 5-nitroisatin are synthesized by a multi-step synthesis from 5-nitroisatin. Whole synthesized analogs were characterized using IR, NMR, Mass spectroscopy and microanalyses. All the Schiff and Mannich bases were tested for their antimicrobial potencies against some human pathogenic microorganism using agar well diffusion technique. The relationship between the biological activity and the functional group variation of the Schiff and Mannich bases were analyzed. Standard ciprofloxacin and ketoconazole were used to compare the antimicrobial activities of novel isatin coupled isoxazole derivatives.

Anti Hiv

In order to elucidate the relationship between the structure and biological activity such as anti-HIV and blood anticoagulant activity, sulfonated polysaccharides and amino-polysaccharides having pentofuranosidic structures were synthesized. These sulfonated polysaccharides had potent anti-HIV activity in spite of low molecular weights, and which was dependent on the degree of sulfonation. For the blood anticoagulant activity, the conformation of polymer backbone and sulfamide group plays an important role on the interactions with the blood anticoagulant factor.

The Relationship

Conventional methods to determine the biomass in activated sludge are the measurement of total suspended solids (TSS) and volatile suspended solids (VSS). Such methods do not distinguish between active biomass and inactive organic material. In this study, biomass was determined with both conventional methods and also through measuring the protein content with the modified Lowry method. In order to investigate the relationship between activity and biomass concentration in terms of TSS, VSS and protein content, some starvation experiments were conducted. It was found that the protein fraction of VSS differs under different starvation conditions. The biological activity of the activated sludge was measured as oxygen uptake rate (OUR). The strongest correlation could be measured between protein and OUR under various conditions. The results show that protein is an appropriate parameter for the measurement of the biological activity.
