Abstract

Nine novel 4-aminoquinazoline derivatives were designed and synthesized. Biochemical and cellular analyses demonstrated that most of the derivatives exhibited a strong activity to inhibit Aurora A and B kinases and to suppress the proliferation of a panel of human tumor cell lines (U937, K562, A549, LoVo, and HT29). Quantum chemical studies were also carried out to determine the structural features of these compounds engaged in the inhibition of Aurora kinases.
