2-Aminoxazole and 2-Aminothiazole Dasatinib Derivatives as Potent Inhibitors of Chronic Myeloid Leukemia K562 Cells

Dasatinib is an important drug against chronic myeloid leukemia (CML). In this paper, we describe the preparation and anti-CML activity of 2-aminoxazole and 2-aminothiazole dasatinib derivatives. Biological activity was measured by the inhibition of proliferation of human CML K562 cells. The 2-aminoxazole derivatives had similar activities as the 2-aminothiazole derivatives. All newly synthesized compounds demonstrated more potent antiproliferative activity than imatinib. A few compounds (8b, 8c, 9b) showed nanomolar inhibitory activity, similar to that of dasatinib.
