The present invention is directed to substituted nicotinamides and analogs thereof, represented by Formula V:
1
or a pharmaceutically acceptable salt or prodrug thereof, wherein:
Ar′ and Ar are independently optionally substituted aryl or optionally substituted heteroaryl, provided that the ring structure of said optionally substituted heteroaryl comprises not more than two nitrogen atoms; and
R
11
is hydrogen; or alkyl, cycloalkyl, aryl or heteroaryl, each of which is optionally substituted.
The present invention also relates to the discovery that compounds having Formula V are activators of caspases and inducers of apoptosis. Therefore, the compounds 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.
本发明涉及被代换的烟酰胺和其类似物,由化学式V:1或其药学上可接受的盐或前药所代表,其中:Ar′和Ar分别是可选择代替的芳基或可选择代替的杂芳基,前提是所述可选择代替的杂芳基的环结构不超过两个氮原子;以及R11为氢;或烷基,环烷基,芳基或杂芳基,每种都可选择代替。本发明还涉及发现具有化学式V的化合物是caspases的激活剂和凋亡诱导剂。因此,本发明的化合物可用于诱导在各种临床病况中发生未受控制的异常细胞生长和扩散的细胞死亡。
