Synthesis of New 'Hybrid' Compounds Based on Benzofuroxans and Aminoalkylnaphthalimides.

Pathogenic bacteria and fungi eventually develop resistance to existing drugs, and therefore, we need constant development of new drugs. The research is aimed at addressing fundamental scientific problems-the search for new biologically active compounds among several benzofuroxan-containing 'hybrid' products. N-substituted naphthalimides were chosen as a second pharmacophore. Benzofuroxanes biological effects were studied by means of bacterial lux-biosensors. Compounds IIIa, IVa, IIIc, and IVc displayed more expressed bacteriotoxic action in comparison with the initial substances Ia-c and represent a certain interest for using as antibacterial substances.
