Considering the side effects of existing drugs used for pain relief, the search for new analgesics with high efficacy and safety remains relevant. Aseries of imidazopyrrolo[3,4-b]quinoline-5,11-diones and pyrimidopyrrolo[3,4-b]quinoline-6,12-diones II were synthesized, whose analgesic activity at a dose of 0.05 mmol/kg was studied in the hotplate test in rats after i.p. administration. One compound was found with analgesic activity comparable to that of reference compound diclofenac sodium. Compounds II were less toxic than diclofenac sodium.
