The article is devoted to the targeted synthesis and study of cyclic thiourea and their various new derivatives as new organic compounds containing polyfunctional group in the molecule. First time the reaction of the corre-sponding synthesized pyrimidinethione with 1,2-epoxy-3-chlorpropane at the presence of AlCl3 catalyst in 75-80% yield alkyl-1-(3-chloro-2-hydroxypropyl)-4-alkyl-6-phenyl-2-thioxo-1,2,5,6- tetrahydropyrimidine-5-carboxylates. In the next stage, new cyclic thiourea derivatives of aminoalcohols were synthesised from the reaction of chlorinated derivatives of pyrimidinethiones with single amines and their structures were investigated by spectroscopic methods. In this study, a series of novel compounds were tested towards some metabolic enzymes including alpha-glycosidase (alpha-Gly) and alpha-amylase (alpha-Amy) enzymes. Novel compounds showed Kis in ranging of 10.43 +/- 0.94-111.37 +/- 13.25 mu M on alpha-glycosidase and IC50 values in ranging of 14.38-106.51 mu M on alpha-amylase. The novel cyclic thiourea derivatives of aminoalcohols had effective inhibition profiles against all tested metabolic enzymes. Binding affinity and inhibition mechanism of the most active compounds were detected with in silico studies and have shown that 2-Hydroxypropyl and butan-1-aminium moieties play a key role for inhibition of the enzymes.
