The present invention is directed to optionally substituted 4-substituted-1-(arylmethylidene)thiosemicarbazide, 4-substituted-1-(arylcarbonyl)thiosemicarbazide and analogs thereof, represented by the Formulae I and II:
wherein A1, A2, Q and R1-R3 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-(芳基甲基亚硫基)脲、4-取代-1-(芳基羰基)亚硫基脲及其类似物,其化学式分别为I和II:其中A1、A2、Q和R1-R3在此定义。本发明还涉及发现具有化学式I和II的化合物是caspase的激活剂和凋亡诱导剂。因此,本发明的caspase激活剂和凋亡诱导剂可用于在各种临床情况下诱导细胞死亡,其中出现了异常细胞的不受控制的生长和扩散。
