Synthesis of sulphonamidoquinoline derivatives

In a research for new antimicrobial agents effective in therapy a new series of sulphonamidoquinoline derivatives have been studied. Their molecules, have got the feature of both 1-alkyl-1,4-dihydro-4-oxopyridine-3-carboxylic acid and sulphonamides. The structure of such compounds has been confirmed by chemical and physico-chemical methods and their antimicrobial activity has been tested.
