A series of new 2-amino-4-aryl-6-pyridopyrimidines, and their N-alkyl bromide derivatives were designed and synthesized by employing methyl substituted azachalcones. These novel compounds were evaluated and compared to the well-known chemotherapeutics in terms of their anti-cancer and anti-microbial functions, and their DNA/protein binding affinities. In order for the cell proliferation, cytotoxicity and microdilution features to be observed, various cancer cell lines (Hep3B, A549, HeLa, C6, HT29, MCF7) were treated with 2-amino-4-aryl-6-pyridopyrimidines (1-9) and their N-alkyl bromide derivatives (2a-c, 3a-c, 5a-c, 6a-c, 8a-c, 9a-c). Studies on the cells revealed that both pyrimidines and their alkyl derivatives (i) have a high anti-proliferative and antimicrobial activities, (ii) cause cell rounding, cytoplasmic blebs, and anomalous globular structure, and (iii) strongly bound to DNA/BSA macromolecules. Especially the length of the alkyl chain of the N-alkyl bromides has an increasing effect on the antiproliferative, antibacterial and cytotoxic functions, also DNA/protein binding affinity. Those results indicate the novel compounds to be promising antiproliferative agents, and their anticancer potential makes them candidates to be used for cancer therapy.
