Predict of anxiolytic activity and affinity for the translocator protein (TSPO), compounds in the 1-arylpyrrolo[1,2-a]pyrazine-3-carboxamide series by QSAR (Quantitative structure-activity relationship) and molecular docking was carried out. 9 Models were created from a combination of three methods of machine learning (ASNN, FSMLR, PLS) with a different set of 2D fragmented descriptors (OEState, ISIDA, GSFrag). For the validation of the model, 5-fold cross-checking was used. For molecular docking, the following programs were used: for building 3D ligand models, Marvin software package from ChemAxon, preparation of protein 2MGY (Protein Data Bank) was performed in AutodockTools, and to establish the affinity of Autodock 4.2. In addition, a study was made of the hydrophobic correspondence in the PLATINUM web service. As a result of these studies, the most promising TSPO ligands were identified. Also, the structure-property relationship was evaluated.ΠΡΠΏΠΎΠ»Π½Π΅Π½ΠΎ ΠΏΡΠΎΠ³Π½ΠΎΠ·ΠΈΡΠΎΠ²Π°Π½ΠΈΠ΅ Π°ΡΡΠΈΠ½Π½ΠΎΡΡΠΈ ΠΊ 18 ΠΊΠΠ° ΡΡΠ°Π½ΡΠ»ΠΎΠΊΠ°ΡΠΎΡΠ½ΠΎΠΌΡ Π±Π΅Π»ΠΊΡ (TSPO) ΡΠΎΠ΅Π΄ΠΈΠ½Π΅Π½ΠΈΠΉ Π² ΡΡΠ΄Ρ 1-Π°ΡΠΈΠ»ΠΏΠΈΡΡΠΎΠ»ΠΎ[1,2-Π°]ΠΏΠΈΡΠ°Π·ΠΈΠ½-3-ΠΊΠ°ΡΠ±ΠΎΠΊΡΠ°ΠΌΠΈΠ΄ΠΎΠ² ΠΌΠ΅ΡΠΎΠ΄Π°ΠΌΠΈ QSAR (Quantitative structure-activity relationship) ΠΈ ΠΌΠΎΠ»Π΅ΠΊΡΠ»ΡΡΠ½ΠΎΠ³ΠΎ Π΄ΠΎΠΊΠΈΠ½Π³Π°.
