  Discovery of N-aryl-9-oxo-9H-fluorene-1-carboxamides as a new series of apoptosis inducers using a cell- and caspase-based high-throughput screening assay. 2. Structure–activity relationships of the 9-oxo-9H-fluorene ring

  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.
