[Problem]
A compound which is useful as an agent for treating breast cancer is provided.
[Means for Solution]
As a result of intensive studies on a compound having a Complex I inhibitory effect and an AMPK activation effect, the present inventors found that a bicyclic nitrogen-containing aromatic heterocyclic amide compounds of the present invention has an excellent Complex I inhibitory effect and the AMPK activation effect, furthermore, has a cell proliferation inhibitory effect with respect to not only human PIK3CA mutation-positive breast cancer cell lines in which MCT4 is not expressed but also human breast cancer cell lines which do not have mutation of PIK3CA in which MCT4 is not expressed, and exhibits an anti-tumor effect in a human PIK3CA mutation-positive breast cancer cell line MDA-MB-453 cell in a cancer-bearing mouse in which the MCT4 is not expressed, thereby completing the present invention. A bicyclic nitrogen-containing aromatic heterocyclic amide compound of the present invention can be used as an agent for treating breast cancer, in particular, breast cancer in which the MCT4 is not expressed, and among others, PIK3CA mutation-positive breast cancer in which the MCT4 is not expressed.
提供一种作为治疗乳腺癌药物的化合物。通过对具有复合I抑制作用和AMPK激活作用的化合物进行深入研究,本发明人发现,本发明的含有双环氮杂芳香族酰胺化合物具有优异的复合I抑制作用和AMPK激活作用,此外,对于不仅在其中MCT4不表达的人类PIK3CA突变阳性乳腺癌细胞系,还对于其中MCT4不表达的不具有PIK3CA突变的人类乳腺癌细胞系,具有细胞增殖抑制作用,并在MCT4不表达的癌症携带小鼠的人类PIK3CA突变阳性乳腺癌细胞系MDA-MB-453细胞中表现出抗肿瘤作用,从而完成了本发明。本发明的含有双环氮杂芳香族酰胺化合物可用作治疗乳腺癌的药物,尤其是MCT4不表达的乳腺癌,以及其他MCT4不表达的PIK3CA突变阳性乳腺癌。
