The evaluation of the ecotoxicological effects water pollutants is performed by using different aquatic organisms. seven compounds belonging to a class widespread contaminants, benzo-fused nitrogen heterocycles, on group simple organisms employed in reference ISO tests quality (unicellular algae and luminescent bacteria) have been assessed ascertain their suitability revealing contamination lev...

This paper describes a calorimetric study of the association of a series of seven fluorinated benzenesulfonamide ligands (C6H(n)F(5-n)SO2NH2) with bovine carbonic anhydrase II (BCA). Quantitative structure-activity relationships between the free energy, enthalpy, and entropy of binding and pKa and log P of the ligands allowed the evaluation of the thermodynamic parameters in terms of the two in...
