“…Therefore, it was deduced that 1,3,4-oxadiazole could also serve as an indispensable pharmacophore for new DMI fungicides (Figure 1). In addition, 1,3,4-oxadiazole derivatives are a classic type of fivemembered heterocyclic compounds containing C, N, and O atoms, and have attracted more and more attention due to the importance of oxadiazole derivatives in medicinal chemistry and extensive biological activities, such as antiviral, [16] nematocidal, [17] antifungal, [4,18,19] antitumor, [20][21][22][23] antiinflammatory, [24] α-glucosidase inhibition, [25] and antitubercular activities. [26] Moreover, electron-donating groups (e. g., À O-and-SÀ ) linked with a heteroatomic ring would be conducive to the enhancement of the binding affinity between receptor and ligand, and thus the biological activities of the hybrids could be improved.…”
