Aim. To accomplish the synthesis of new thiosemicarbazides and their cyclic analogues derived from 2-fluorobenzoic acid hydrazide and to evaluate further their anticonvulsant activity. Methods. Organic synthesis, NMR spectroscopy, molecular docking. Results. A number of thiosemicarbazide derivatives have been synthesized by the reaction of 2-fluorobenzoic acid hydrazide with the corresponding isothiocyanates in [the] ethanol medium. The subsequent alkaline dehydrocyclization of thiosemicarbazides led to some new 1,2,4-triazole derivatives. Docking studies were performed to predict [the] anticonvulsant activity for the synthesized compounds on GABA-A receptors and pentameric ion channels of Erwinia chrysanthemi (ELIC). Conclusions. The synthesized thiosemicarbazides and their cyclic analogues [are] characterized as a prospective molecular platform for the creation of new highly active compounds as potential anticonvulsant drugs.
