are defined herein. The present invention also relates to the discovery that compounds having Formulae I and II are activators of caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention may be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.
本发明涉及可选取代的4-取代-1-(芳基甲基亚胺基)硫脲、4-取代-1-(芳基羰基)硫脲及其类似物,由式I和II表示:其中A1,A2,Q和R1-R3在此定义。本发明还涉及发现具有式I和II的化合物是caspase激活剂和凋亡诱导剂的发现。因此,本发明的caspase激活剂和凋亡诱导剂可用于诱导在出现异常细胞的无控制生长和扩散的各种临床情况中的细胞死亡。
