In order to develop a new series of dual inhibitors of SRC and ABL, and to investigate whether the pyrimidin- 4-ylamino moiety is critical for dasatinib’s activity, acetyl substitution was adopted as alternate scaffold at the 2-amino group. Eighteen novel dasatinib derivatives were developed by a parallel synthesis approach and evaluated for their antiproliferative effects. Preliminary tests showed that some of the target compounds IId, IIe and IIf manifested strong antiproliferative activity against MCF-7, MDA-MB 231 and HT-29 cells. Easpecially IId proved to be the most potent compound. Structure-activity relationship studies indicate that the introduction of acetyl substitution as alternate scaffold of pyrimidin-4-ylamino reduced the activity.
