Synthesis and Biological Activity of Some New-8-Hydroxyquinoline
Sulphonamide Derivatives.

Research Abstract
Some new derivatives containing both 8-hydroxyquinoline and sulphonylamino β-lactams and thiazolidinones have been prepared. These compounds were synthesized from the corresponding 8-hydroxyquinoline sulphonylhydrazide (1) by converting it to hydrazones (2). The latter hydrazones (2) were easily transformed to β-lactams (3) and thiazolidinones (4) by cyclocondensation reaction with chloroacetyl chloride and/or mercaptoacetic acid. Some metal chelates with Fe3+. Co2++, Ni2+, Cu2+ and Cd2+ have been prepared for some of the compounds and screened in vitro for their biological activity
