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.
本公开揭示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公式I所示。该化合物对ErbB2酪氨酸激酶具有较高的抑制活性,并且对人类乳腺癌BT-474和人类胃癌细胞NCI-N87表达ErbB2的抑制活性相对较好,同时对EGFR激酶具有相对较弱的抑制活性。换句话说,该化合物是一种高度选择性的针对ErbB2的小分子抑制剂,因此具有很高的安全度,并且可以有效地扩大服药过程中的安全窗口。
