A Review on Novel Synthesis Approaches and Biological Activities of 1,2,4- Oxadiazole and 1,3,4-Oxadiazole Tailored Compounds

Rational design and synthesis of novel compounds with both effectivity and safety properties have always been a formidable task in the development of drugs. Oxadiazoles are heterocyclic bioscaffolds occurring as motifs in drug-like molecules. This review article highlights comprehensive and systematic information of compounds containing 1,2,4-oxadiazoles and 1,3,4-oxadiazole rings. The routes for the synthesis of the oxadiazoles have also been discussed, along with their biological significance. This review may help researchers in rational design for the development of effective and less toxic 1,3,4- oxadiazole based compounds. We present an informative review about the drugs derived from oxadiazole rings and their therapeutic application as well as a brief remark on the future development prospects.
