Biological Characterization of One Oxadiazole Derivative (5(4-Hydroxyphenyl)-2-(N-Phenyl Amino)-1,3,4-Oxadiazole): In Vitro, In Silico, and Network Pharmacological Approaches.

Oxadiazole compounds are of great interest because they have a range of biological activities ranging from antioxidants to anticancer agents. Against this background, we wanted to demonstrate the antioxidant, enzyme inhibitory, and anticancer effects of 5(4-hydroxyphenyl)-2-(N-phenylamino)-1,3,4-oxadiazole (Hppo). Antioxidant abilities were measured through free radical scavenging and reducing power tests. Enzyme inhibitory effects were studied by cholinesterases, tyrosinase, amylase, and glucosidase. The anticancer effect was tested on pancreatic cancer cell lines (PANC-1, CRL-169) and on HEK293 cell lines. The compound showed significant antioxidant activity (particularly in the CUPRAC (cupric acid-reducing antioxidant capacity) assay) and enzyme inhibitory properties (particularly glucosidase inhibition). In the anticancer test, the compound showed strong anticancer activity in pancreatic cancer with apoptotic signaling pathways. These results were confirmed by molecular modeling and bioinformatics tools. Thus, our findings can provide novel and versatile compounds for the development of multidirectional drugs in the pharmaceutical industry.
