Chompound contaning oxadiazole derivatives and their potential therapeutic uses.
Abstract: Derivatives of oxadiazole or furadi azole rings constitute a significant class of heterocyclic substances. Oxadiazole is a heterocyclic, five-membered ring with two carbons, one oxygen atom, two nitrogen atoms, and two double bonds. They are produced by substituting two nitrogen (-N =) atoms for two methylene groups (= CH) in furan. The furan ring's aromaticity was significantly decreased by substituting these groups, resulting in a conjugated diene character. There were …
