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.
为了开发一系列新的SRC和ABL双重
抑制剂,并研究
嘧啶-4-
氨基基团对
达沙替尼活性的重要性,采用了在2-
氨基基团处的 acetyl 取代物作为替代骨架。通过平行合成方法开发了18种新型
达沙替尼衍
生物,并评估了它们的抗增殖效果。初步测试显示,一些目标化合物IId、IIe和IIf对MCF-7、
MDA-MB 231和HT-29细胞表现出了强抗增殖活性,尤其是IId被证明是最有效的化合物。结构-活性关系研究表明,引入acetyl取代物作为
嘧啶-4-
氨基的替代骨架降低了其活性。
