New Potential Antitumor Pyrimidine Derivatives: Synthesis and Cytotoxicity Evaluation

Abstract

A new series of pyrimidine derivatives are reported here as antitumor agents such as pyrimidine carboxamide linked to thiophene, pyrazole, and thiazole moieties have been synthesized from the readily available (2-cyano-N-(5-cyano-2-phenyl-6-arylpyrimidin-4-yl)acetamide (6a,b). All the new compounds were screened for their antitumor activity in vitro against a panel of three human tumor cell lines namely, hepatocellular carcinoma (liver) HepG2, colon cancer HCT-116, and mammary gland breast MCF-7. Compounds 9b, 10b, 11b, and 19b displayed a significant therapeutic activity. All the synthesized new compounds were established their structures by means of spectroscopic analysis.
