RELEVANCE AND PROSPECTS OF SEARCHING FOR DRUGS WITH ANXIOLYTIC ACTIVITY BASED ON SYNTHETIC ACTIVE SUBSTANCES CONTAINING 1,3,4-OXADIAZOLE RING

Derivatives of oxadiazole or furadiazole rings are known to be a significant family of heterocyclic compounds. Oxadiazole is a five-membered heterocyclic ring with two carbons, one oxygen atom, two nitrogen atoms, and two double bonds. They are made from furan by substituting two nitrogen (-N =) atoms for two methylene groups (= CH). By substituting these groups in the furan ring, the aromaticity was decreased to the point where conjugated diene character is evident. There were four distinct oxadiazole isomers that were known to exist: 1,2,4-oxadiazole, 1,2,3-oxadiazole, 1,2,5-oxadiazole, and 1,3,4-oxadiazole. 1,3,4-thiadiazole's chemistry is one of the most intriguing scaffolds for creating novel therapeutic compounds because of its many pharmacological properties. Numerous changes have been made to the thiadiazole ring, which has demonstrated that it is more powerful and highly useful for a variety of biological functions with a less hazardous structure. Numerous medications on the market have a 1,3,4-thiadiazole ring in their composition.
