Анальгетическая активность новых производных серосодержащих ди- и тетрагидропиридинов в тесте горячей пластины

Abstract

Nowadays the search of new high-efficiency and safe drugs for the pharmacotherapy of diseases accompanied by pain syndrome is an active area of modern pharmacological research. 170 new derivatives of di- and tetrahydropyridines synthesized on the basis of the Chemex Research Laboratory, Vladimir Dahl Lugansk State University were exposed to the virtual bioscreening using the Swiss Target Prediction software. The paper describes screening studies in vivo of 5 samples of sulfur-containing di- and tetrahydropyridines (laboratory codes d02-138, as-262, f02-079, cv-074, cv-143) in the standard hot plate test in comparison with the reference drug — metamizole sodium. The compounds in the dose of 5 mg/kg were given intragastrically 1 hour and a half before placing the rats on the hot plate, the reference drug in the dose of 7 mg/kg also was given intragastrically 1 hour and a half before placing the rats on the hot plate. The compounds with laboratory codes as-262 (allyl 6-({2-[(4-acetylphenyl)amino]-2-oxoethyl}thio)-5-cyano-4-(2-furyl)-2-methyl-1,4-dihydropyridine-3-carboxylate) and d02-138 (ethyl 4-[({[3-cyano-5-{[(2,4-dichlorophenyl)amino]carbonyl}-4-(2-furyl)-6-methyl-1,4-dihydropyridinе-2-yl]thio}acetyl)amino]benzoate) possess the most pronounced analgesic activity in the dose of 5 mg/kg, they demonstrated 2.03 and 1.9-fold efficiency in comparison to metamizole sodium respectively. The rest three specimens demonstrated metamizole sodium-like analgesic activity.
