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 Il 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.
本发明一般涉及治疗化合物领域,更具体地涉及某些联苯胺化合物(在此称为BAA化合物),特别是某些式(I)的吡啶-2-基-吡啶-2-基-胺和吡嗪-2-基-吡啶-4-基-胺化合物,该化合物等抑制检查点激酶1(CHK1)激酶功能。本发明还涉及包含这种化合物的药物组合物,以及利用这种化合物和组合物在体外和体内抑制CHK1激酶功能,并治疗由CHK1介导的疾病和症状,通过抑制CHK1激酶功能而得到缓解的疾病和症状,包括增生性疾病如癌症等,可选择与另一药剂结合,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=独立为-CRA5=或-N=;其余取代基如索引中所述。
