Synthesis, Single Crystal X-Ray Analysis, Prediction and Study of Pharmacological Activity of 4-(1H-Benzo[d]imidazol-2-yl)-1-Phenyl-1H-1,2,3-triazol-5-Amine and Its Solvates

A method for the synthesis of 4- (1H-benzo[d]imidazole-2-yl)-1-phenyl-1H-1,2,3-triazole-5-amine was developed, and the electronic and spatial structure of this molecule was studied theoretically and experimentally. The study of interaction energies between molecules by quantum-chemical calculations allows us to recognize different levels of crystal structure organization and describe the interaction types causing their formation. The classic N-H…N and C-H…N hydrogen bonds play the main role in all the studied crystals forming the primary basic structural motif. Their role is comparable with the role of the stacking interactions. The molecular docking study predicted that the studied compound may exhibit anti-hepatitis B activity, and experimental in vitro studies confirmed that it is a potent HBV inhibitor with IC₅₀ in a low micromolar range.
