Abstract A new fluorine derivative of triazole-3-thione has been synthesized as a potential neuroprotector. The structure and purity of the compound were confirmed by 1H NMR, 13C NMR and elemental analysis. The in vitro study of the biological activity of the compound was carried out: the calcium-blocking ability and the effect on the functional activity of AMPA receptors. The shake flask method was used to measure the solubility of the compound in solvents imitating the body's media in the temperature range of 293–313 K. The temperature dependences of the compound solubility were modeled using the Van't Hoff and Apelblat equations. The lipophilicity of the compound was determined and it was concluded that it should have a good intestinal absorption. On the basis of the calculated dissolution and distribution thermodynamic functions, the analysis of the influence of enthalpy and entropy contributions on the Gibbs energy of these processes was carried out. The permeability of the compound through artificial lyotropic phospholipid membranes was studied. It was found that the permeability is sufficient to pass through the body’s biological cell membranes.
