Oxadiazoles are a class of heterocyclic aromatic compounds with the molecular formula C2H2N2O, which have special biological activities and thermodynamic properties. Five-membered heterocyclic moieties composed of three or two heteroatoms are of great interest to researchers because these compounds show significant therapeutic potential. These heterocycles can serve as a building block for the development of novel molecular structures.
The pyrazolopyrazine ring system is a very interesting class of heterocyclic compounds considered as important scaffolds for many effective bioactive agents with low toxicity, antioxidant, anticonvulsant, antiparasitic, anti-inflammatory, antiviral, antibacterial, anti- Fungal and analgesic activity.
