Synthesis, antiviral, antituberculostic, and antibacterial activities of some novel, 4-(4-substituted phenyl)-6-(4-nitrophenyl)-2-(substituted imino)pyrimidines

A variety of novel 4-(4-substituted phenyl)-6-(4-nitrophenyl)-2-substituted imino) pyrimidines were synthesized by reacting 4-(4-substituted phenyl)-6-(4-nitrophenyl)-2-amino pyrimidines with different substituted aromatic aldehydes, coumarin chloroisatin. The 4-(4-substituted phenyl)-6(4-nitrophenyl)-2-amino pyrimidines were synthesized by reacting 3-(4'-substituted phenyl)-1-(4-nitrophenyl)-2-propen-1-ones with guanine hydrochloride. 3-(4-substituted phenyl)-1-(4-nitrophenyl)-2-propen-1-ones were synthesized by reacting 4-nitroacetophenone with different para-substituted aromatic aldehydes. Spectral data (IR, NMR, and mass spectra) confirmed the structures of the synthesized compounds. The synthesized compounds were investigated for their antiviral, antituberculostic, and antibacterial activities. The results of antiviral, antituberculostic, and antibacterial activities indicated that the synthesized compounds exhibited mild to potent activities compared to the respective reference standards.
