Synthesis, Biological and Pharmacological Screening of Novel Pyrimidine Derivatives

A series of novel 4-(4-nitrophenyl)-6-phenyl substituted pyrimidine-2-thiol (PM₁-PM₆) have been synthesized by refluxing 1-(4-nitrophenyl)-3-phenyl substituted prop-2-en-1-one in presence of thiourea and glacial acetic acid. 1-(4-nitrophenyl)-3-phenyl substituted prop-2-en-1-one were prepared by condensing 4-nitroacetophenone with substituted benzaldehydes in presence of 20% NaOH as base. The structures of newly synthesized compounds were characterized by IR, ¹H NMR and mass spectroscopic studies. Newly synthesized compounds were screened for their anti-inflammatory and cytotoxic studies. Few of the compounds exhibited excellent anti-inflammatory compared to the standard drug diclofenac sodium. Some compounds have shown moderate cytotoxic activities.
