Cytotoxic and Apoptotic Effects of Novel Pyrrolo[2,3-d]Pyrimidine Derivatives Containing Urea Moieties on Cancer Cell Lines

Background: Pyrrolo[2,3-d]pyrimidines have been recently reported to have anticancer activities through inhibition of different targets such as, Epidermal Growth Factor Receptor (EGFR) tyrosine kinase, Janus Kinase (JAK), mitotic checkpoint protein kinase (Mps1), carbonic anhydrase, MDM-2. On the other hand, aryl urea moieties which are found in some tyrosine kinase inhibitors such as Sorafenib and Linifanib have aroused recent attention as responsible for anticancer activities. The aims of this paper are to synthesize pyrrolo[2,3-d]pyrimidine derivatives containing urea moiety and evaluate their anti-cancer activity against human lung cancer cell line (A549), prostate cancer cell line (PC3), human colon cancer cell line (SW480) and human breast cancer cell line (MCF-7).
