Disclosed are a nitrogenous heterocyclic compound, intermediates, a preparation method, a composition and use thereof. The nitrogenous heterocyclic compound in the present invention is as shown in formula I. The compound has a high inhibitory activity towards ErbB2 tyrosine kinase and a relatively good inhibitory activity towards human breast cancer BT-474 and human gastric cancer cell NCI-N87 which express ErbB2 at a high level, and at the same time has a relatively weak inhibitory activity towards EGFR kinase. Namely, the compound is a highly selective small-molecule inhibitor targeted at ErbB2, and hence it has a high degree of safety, and can effectively enlarge the safety window in the process of taking the drug.
本发明公开了一种含氮杂环化合物、中间体、制备方法、组合物及其用途。本发明中的含氮杂环化合物如式 I 所示。该化合物对 ErbB2 酪氨酸激酶有较高的抑制活性,对高水平表达 ErbB2 的人乳腺癌 BT-474 和人胃癌细胞 NCI-N87 有较好的抑制活性,同时对表皮生长因子受体激酶的抑制活性相对较弱。也就是说,该化合物是一种针对 ErbB2 的高选择性小分子抑制剂,因此具有很高的安全性,可以有效地扩大用药过程中的安全窗口期。
