Biological activity of 4-ethynyl-, 4-oxy-, 4-butoxypropylpyperidine and azaheterocyclic compounds

Abstract

The new chemical series of compounds is promising for the search new effective immunostimulating drugs. Acute toxicity and the effect on peripheral blood hemogram parameters and on the subpopulation composition of lymphocytes were determined in the compounds (piperidine-containing derivatives): 1-(3-n-butoxypropyl)-piperidine-3-methyl-4-spiro-5'-imidazolidine-2',4'-dione,1-(2-ethoxyethyl)-4-carboxy-4-hydroxypiperidine, bis[1-(2-ethoxyethyl)-4-ethynyl-4-hydroxypiperidine) dihydrochloride and, 1:1 complexes of β-cyclodextrin with 1-(2-ethoxyethyl)-4-(2-ethoxyethoxyl)-4-ethynylpiperidine, 1-(2-ethoxyethyl)-4-(2-methoxyethoxyl)-4-ethynylpiperidine, 7-(2-methoxyethyl)-2,2-dimethyl-3-thia-7-azabicyclo[3.3.1]nonane or 3-(2-morpholinoethyl)-7-(3-isopropoxypropyl) diazabicyclo[3.3.1] nonane with β-cyclodextrin. Compound ˗ 1-(3-n-butoxypropyl)piperidine-3-methyl-4-spiro-5'-imidazolidine-2',4'-dione, exceeds the immunostimulating activity of the comparison drug of levamizole by 3,1 times and has low toxicity.
