BACKGROUND Translocator protein 18 kDa (TSPO) is a promising target for the creation of effective and safe neuropsychotropic drugs. The ligands of TSPO exhibit anxiolytic, antidepressant, neuroprotective and other activities without the side effects of benzodiazepines. METHODS New TSPO ligands in the series of N,1-diphenylpyrrolo[1,2-a]pyrazine-3-carboxamides derivatives were designed using calculated pharmacophore model and molecular docking analysis. The synthesis of new compounds was carried out by two schemes using [3+3]-cycloaddition reaction of 2-azidoacrylic acid derivatives with pyrrolphenylketone as a key stage. The anxiolytic activity of new substances has been established using open field test with flash. RESULTS Several synthesized N,1-diphenylpyrrolo[1,2-a]pyrazine-3-carboxamides derivatives significantly increased the total motor activity of Balb/c mice compared to the control. The structureactivity relationship was investigated. The most effective compound was found to be GML-11 (Nbenzyl- N,1-diphenylpyrrolo[1,2-a]pyrazine-3-carboxamide), which had anxiolytic action in the dose range from 0.001 to 0.100 mg/kg (Balb/c, i.p.). This compound is two orders of magnitude higher in dose activity than all other pyrrolo[1,2-a]pyrazine TSPO ligands. CONCLUSION Molecular modelling methods allowed us to create new TSPO ligands in the series of N,1-diphenylpyrrolo[1,2-a]pyrazine-3-carboxamides with high anxiolytic activity.
