1, 3, 4-Oxadiazole: A Versatile Compound With Potent Analgesic Activity
Oxadiazole is a heterocyclic ring with 5 members that has 1 oxygen atom, 2 nitrogen atoms, 2 double bonds, and 2 carbons. In furan, they are created by placing two methylene groups (=CH) for two nitrogen (-N=) atoms. The aromaticity was reduced by the substitution of these groups. There were four different isomer of oxadiazole that were identified: 1,3,

A Review On: Antifungal And Antibacterial Activity Of 1, 3, 4-Oxadiazole Derivatives
1,3,4-Oxadiazoles are five-membered heterocyclic compounds containing two nitrogen atoms and one oxygen atom. These versatile molecules exhibit a range of biological effects, including antibacterial, antifungal, and antiviral properties. Recent research has demonstrated that many 1,3,4-oxadiazole derivatives surpass the activity of existing antibiotics
