Five Lapatinib derivatives were designed by structurally modifying the side chain as well as
the aniline substituent. The ELISA assay showed that the derivatives retained or even improved the
inhibitory activity of Lapatinib against HER1/HER2. In vitro cytotoxicity assay revealed that the derivatives significantly
inhibited the proliferation of the HER1/HER2-overexpressing cancer cells. Furthermore, molecular modeling study suggested
that the derivative could effectively enter the ATP binding pocket of HER1 and interact with the corresponding
residues in a manner similar to Lapatinib.
通过对侧链和苯胺取代基进行结构改造,设计出了五种拉帕替尼衍生物。酶联免疫吸附试验表明,这些衍生物保留甚至提高了拉帕替尼对 HER1/HER2 的抑制活性。体外细胞毒性实验表明,这些衍生物能显著抑制 HER1/HER2 基因表达癌细胞的增殖。此外,分子建模研究表明,该衍生物能有效进入 HER1 的 ATP 结合袋,并以类似拉帕替尼的方式与相应残基相互作用。
