The present invention pertains generally to the field of therapeutic compounds, and more specifically to certain biarylamine compounds (referred to herein as BAA compounds), and especially certain pyrazin-2-yl-pyridin-2-yl-amine and pyrazine-2-yl-pyrimidin-4-yl-amine compounds of formula (I), which, inter alia, inhibit Checkpoint Kinase 1 (CHK1) kinase function. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit CHK1 kinase function, and in the treatment of diseases and conditions that are mediated by CHK1, that are ameliorated by the inhibition of CHK1 kinase function, etc., including proliferative conditions such as cancer, etc., optionally in combination with another agent, for example, (a) a DNA topoisomerase I or II inhibitor; (b) a DNA damaging agent; (c) an antimetabolite or TS inhibitor; (d) a microtubule targeted agent; and (e) ionisiπq radiation, wherein: —X═ is independently —CRA5═ or —N═; and the rest of the substituents are as specified in the claims.
本发明涉及治疗化合物领域,更具体地涉及某些双芳基胺化合物(以下简称BAA化合物),特别是公式(I)中的某些吡嗪-2-基吡啶-2-基胺和吡嗪-2-基嘧啶-4-基胺化合物,其中,除其他作用外,抑制检查点激酶1(CHK1)的激酶功能。本发明还涉及包含这些化合物的制药组合物,并且在体内外使用这些化合物和组合物来抑制CHK1激酶功能,并治疗由CHK1介导的疾病和病况,这些病况通过抑制CHK1激酶功能得到改善等,包括增殖性疾病如癌症等,可选地与另一种制剂联合使用,例如(a)DNA拓扑异构酶I或II抑制剂;(b)DNA损伤剂;(c)抗代谢物或TS抑制剂;(d)微管靶向剂;和(e)电离辐射,其中:—X═独立地为—CRA5═或—N═;其余取代基如权利要求中所述。
