Novel pyrimidine and its triazole fused derivatives: Synthesis and investigation of antioxidant and anti-inflammatory activity

In the present study, we have carried out the synthesis of novel dihydropyrimidinecarbonitrile (1a–c), its dimethylated adduct (2a–c), and hydrazine derivative (3a–c) of 2a–c and its triazole fused derivatives (4a–c, 5a–c and 6a–c). The structure of newly synthesized compounds was confirmed by IR, ¹H NMR, mass spectral data and elemental analysis. Further the novel derivatives were investigated for their in vitro antioxidant and anti-inflammatory activity. The results revealed that some of the tested compounds showed potent antioxidant and anti-inflammatory activity. The mass spectral pattern of 6a has been investigated in order to elucidate the structure.
