QSAR analysis of two sets of analogues of 2-oxo-1,2,3,4-tetrahydropyrimidine was performed to investigate the relationship between their physicochemical parameters and antibacterial activity. Predictive and statistically significant models were generated. On the basis of these models new compounds were synthesized, structurally characterized and evaluated for their antibacterial potential. The potential of newly synthesized compounds was higher than the training set of compounds, in close agreement with QSAR prediction.
