Background: Pyrimidine and fused pyrimidine derivatives play an important role in therapeutic strategies. It is known to be most prominent structures found in nucleic acid, including uracil, thymine, cytosine, adenine, and guanine, which are fundamental building blocks for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Materials and Methods: A series of 3-[2-amino-6-(substituted)-pyrimidin-4-yl]-6-(substituted)-2H-chromen-2-one derivatives were prepared by reacting salicylaldehyde with ethylacetoacetate in the presence of piperidine by Knoevenagel reaction as a starting material. The chemical structures were confirmed by means of FTIR (Fourier Transform InfraRed Spectrophotometer-8400S), 1H NMR, and elemental analysis. The data of these synthesized compounds were submitted to National Institute of Health, USA, under the drug discovery program of NCI (National Cancer Institute) and screened for anticancer activity at a single high dose (10−5 M) in full NCI 60 cell lines. Results: Unfortunately, the selected compounds have not shown any potent significant anticancer activity in the NCI 60 cell line screening. Conclusion: The compound (T2) found to be most efficient anticancer activity with selective influence on breast cancer cell lines, especially on MCF7 cell line with a growth percentage of 33.63.
