and partially saturated pyridine fragments was obtained based on the reaction of cyanothioacetamide with furfural and 1,3-dicarbonyl compounds. The resulting compounds were tested in vivo for analgesicactivity (rats) in the orofacial trigeminal pain test. Some the tested compounds showed an antinociceptive effect, superior to that of the reference drug (metamizole sodium).

condensation of aromatic aldehydes, cyanothioacetamide, 1-(cyclohex-1-en-1-yl)azepine, and α-halocarbonyl compounds was studied. As a result, new derivatives of partially hydrogenated quinolines were synthesized. The molecular and crystal structures of a number of the synthesized heterocycles were studied X-ray analysis.
