Abstract On the basis of 4-(thien-2-yl)-3-aminopyridine-2(1 H )-one, the corresponding chloroacetamide and condensed 1 H -pyrido[2,3 -b ][1,4]oxazine-2(3H)-one were synthesized by the reaction of acylation with chloroacetyl chloride. Thioureide derivatives of 3-aminopyridine-2(1 H )-one were obtained by reactions with a number of isothiocyanates. It was shown that the carbamothionylmethacrylamide derivative cyclizes rather easily into substituted 1,3-thiazine. Molecular docking of synthesized derivatives for antithrombotic activity was carried out, which showed that the presence of a thiourea fragment in the pyridone core leads to an increase in affinity for the selected protein. The hemorheological study of the compounds using the in vitro model of the increased blood viscosity syndrome also showed activity at the level of the reference drug pentoxifylline.
