| Abstract: | A series of Pyrido[2,3‐d]pyrimidine have been synthesized through a reaction of cyanoacetylurea derivatives with aromatic aldehydes or Arylidines. Reaction of compound 1 with aromatic arylidine derivatives or arylhydrazones gave Chromeno[3,4‐c]pyridine, Pyridine, Pyrimido[2,3‐c]pyridazine, Enediamines, and Pyridazine derivatives. All the synthesized compounds were confirmed by spectral studies and screened for their in antibacterial activity against Staphylococcus aureus (Gram positive) and Escherichia coli (Gram negative) bacterial strains. All the compounds were weak to good active against the tested bacterial strains on comparing with the standard drug gentamicin. |
