Xanthineoxidase (XO) has emerged as an important target for the treatment of hyperuricemia and gout. In this study, to obtain novel nonpurine XO inhibitors, a series of 1-alkyl-5/6-(5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)-1H-indole-3-carbonitriles (1a-1u, 2c, 2e, 2h and 2n) were designed using a bioisosteric replacement strategy and were synthesized through a five-step procedure with good yields.
