摘要：

In this paper, we reported the synthesis of coumarin-pyrimidine derivatives by a four-component reaction involving 4-hydroxycoumarin, aldehyde, thiobarbituric acid and piperidine in ethanol. All the synthesized compounds were well-characterized by IR, NMR and mass spectroscopic techniques. Further, to evaluate the biological potency of the synthesized compounds, initially, DNA cleavage studies were performed. Encouraged by the results obtained from the cleavage studies, the synthesized compounds were screened for in-vitro antibacterial and anti-inflammatory activity. From the biological activity results, it revealed that most of the synthesized compounds were found to exhibit potent antimicrobial and anti-inflammatory activity with least IC 50 than compared with standard.
