  摘要：

  As a continuation of our studies of apoptosis inducing 9-oxo-9H-fluorene-1-carboxamides as potential anticancer agents, we explored modi. cation of the 9-oxo-9H-fluorene ring. SAR studies showed that most changes to the 9-oxo-9H-fluorene ring were not well tolerated, except the 9H-fluorene (2b) and dibenzothiophene (2d) analogs, which were about twofold less active than the 9-oxo-9H-fluorene analog 2a. Significantly, introduction of substitutions at the 7-position of the 9-oxo-9H-fluorene ring led to compounds 5a-5c with improved activity. Compound 5a was found to have EC50 values of 0.15-0.29 mu M against T47D, HCT116, and SNU398 cells, about fivefold more potent than the original lead 2a. As opposed to the original lead compound 2a, compounds 5a-5b were active in a tubulin inhibition assay, indicating a change of mechanism of action. The potent azido analog 5c could be utilized for target identification. (C) 2009 Published by Elsevier Ltd.

  The present invention is directed to substituted N-aryl-9-oxo-9H-fluorene-1-carboxamides and analogs thereof, represented by the general Formula I: (I) wherein R 1 -R 8 , X and Ar are defined herein. The present invention also relates to the discovery that compounds having Formula I are activators of caspases and inducers of apoptosis. Therefore, the activators of caspases and inducers of apoptosis of this invention can be used to induce cell death in a variety of clinical conditions in which uncontrolled growth and spread of abnormal cells occurs.

  本发明涉及取代的N-芳基-9-氧代-9H-芴-1-羧酰胺及其类似物，由通式I表示：（I）其中R1-R8、X和Ar的定义如本文所述。本发明还涉及发现具有I式化合物的化合物是caspase的活化剂和凋亡诱导剂。因此，本发明的caspase活化剂和凋亡诱导剂可用于在发生异常细胞的无控制生长和扩散的各种临床情况下诱导细胞死亡。
