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.

In an attempt to develop potent and selective anti-tumor drugs, a series of novel 2-amino-thiazole-5-carboxylic acid phenylamide derivatives were designed based on the structure of dasatinib. All compounds were synthesized by a systematic combinatorial chemical approach. Biological evaluation revealed that N-(2-chloro-6-methylphenyl)-2-(2-(4-methylpiperazin-1-yl)acetamido) thiazole-5-carboxamide (6d) exhibited high antiproliferative potency on human K563 leukemia cells comparable to dasatinib. Against mammary and colon carcinoma cells 6d was either inactive (MDA-MB 231) or distinctly less active (MCF-7 and HT-29: IC50=20.2 and 21.6μM, respectively). Dasatinib showed at each cell line IC501μM. The results of this structure activity relationship study clearly documented that the pyrimidin-4-ylamino core of dasatinib is responsible for the anti-tumor activity against non-leukemia cell lines.
