Twenty-four derivatives of N,N-dimethylbarbituric acid 1-24 were screened for their DPPH radical scavenging activity. These compounds showed an excellent antioxidant activity. A structure-activity relationship has been discussed, while all the synthetic compounds were characterized by spectroscopic techniques and elemental analysis.
