A Review of the Biological Activities of Heterocyclic Compounds Comprising Oxadiazole Moieties

Abstract

Abstract: The oxadiazole core is considered a privileged moiety in many medicinal chemistry applications. The oxadiazole class includes 1,2,3-oxadiazole, 1,2,4-oxadiazole, 1,3,4-oxadiazole, and 1,2,5-oxadiazole. Compounds bearing an oxadiazole ring show a wide range of biological activities, such as anticancer, antibacterial, anti-inflammatory, anti-malarial, and insecticidal properties. Among oxadiazoles, the 1,3,4-oxadiazole has been the most widely explored moiety in medicinal chemistry research. This review is primarily focused on the anticancer, antibacterial, and anti-inflammatory activities of compounds containing 1,2,4-oxadiazole, 1,3,4-oxadiazole and 1,2,5-oxadiazole reported in the last five years.
