Synthesis and Biological Evaluation of Amidinourea and Triazine Congeners as Inhibitors of MDA-MB-231 Human Breast Cancer Cell Proliferation.

A series of novel amidinourea derivatives was synthesized, and the compounds were evaluated as inhibitors of MDA-MB-231 human breast cancer cell proliferation. In addition, a second series of triazine derivatives designed as rigid congeners of the amidinoureas was synthesized, and the compounds were evaluated for their antiproliferative activity. Among the two series, amidinourea 3 d (N-[N-[8-[[N-(morpholine-4-carbonyl)carbamimidoyl]amino]octyl]carbamimidoyl]morpholine-4-carboxamide) emerged as a potent anticancer hit compound with an IC ₅₀ value of 0.76 μm, similar to that of tamoxifen.
