A novel series of 3,5-disubstituted-1a,3,4-oxadiazole derivatives was synthesized and screened for in vitro anticancer activity. The newly synthesized compounds were characterized by(1)H,C-13 NMR, IR spectroscopy and mass spectrometry. Among all the synthesized compounds, Oxaprozin derivatives containing 1,3,4-oxadiazole ring with 4-fluorobenzyl, 4-methoxybenzyl, methyl, and butyl substituents showed promising anticancer activity against HTB-57 cancer cell line, and derivatives with 4-fluorobenzyl, 4-methoxybenzyl, and propyl substituents exhibited a higher anticancer activity against a PPC-1 cell line. The possible binding mode interactions of the synthesized compounds with the key active site of the proline rich tyrosine kinase 2 Pyk2 receptor (PDB ID: 5TO8) were investigated using the AutoDock 4.2 docking protocol to find that the 1,3,4-oxadiazole Oxaprozin derivatives with methyl, ethyl, and propyl substituents had the highest binding energies (Delta G= -7.8, -7.6, and -6.8 kcal/mol, respectively) with Glu441, Leu431, Ala455, Val487, Met502, Leu556, Lys457, and Glu509.
