A class of innovative benzimidazole-1,3,4-Oxadiazole derivatives is a significant heterocyclic molecule for therapeutic development. In chemistry, the novel 1,3,4-Oxadiazole nucleus has wide range uses, including antibacterial, treatment. Molecular docking frequently employed in contemporary drug design to comprehend drug-receptor interaction. Swiss dock, PyRx, and discovery studio visualizer (...

Benzodiazepines are useful drugs for treatment of sleep disorders, anxiety, seizure cases and skeletal muscle cramps. Some derivatives of 2-(2-Phenoxy) phenyl-1, 3, 4-oxadiazole were synthesized as benzodiazepine receptor agonists. Conformational analysis and superimposition of energy minima conformers of the compounds on estazolam, a known benzodiazepine agonist, reveal that the main proposed ...

The addition of various nucleophiles to a vinyl 1,2,4-oxadiazole is described. Following optimisation, individual protocols tuned for the use of each specific class of reagent have been developed to allow the installation of nitrogen, sulfur, oxygen, and carbon nucleophiles, and leading to the preparation of a series of compounds containing the pharmaceutically important oxadiazole motif.

In the crystal structure of the title compound, C(20)H(12)N(6)O(2), the mol-ecules are located on centres of inversion. The complete mol-ecule is almost planar, with a maximum deviation from the mean plane of 0.0657 (1) Å for the O atom. In the crystal, mol-ecules are stacked into columns elongated in the a axis direction. The centroid-centroid distances between the aromatic rings of the mol-ec...
