Abstract

Chemical agents, such as disulfonamide derivatives of fluorene, anthracene, xanthene, dibenzosuberone and acridine, and similar heterocyclic ring structures, including salts thereof, that act as anti-cancer and anti-tumor agents, especially where such agents modulate the activity of the Wnt/β-catenin signaling pathway, and serve to reduce β-catenin levels present in cells, such as cancer cells, or where the agents modulate levels of gene expression in cellular systems, including cancer cells, are disclosed, along with methods for preparing such agents, as well as pharmaceutical compositions containing such agents as active ingredients and methods of using these as therapeutic agents.

Claims (10)

1. A compound of formula III

wherein R A is hydrogen, R 7 and R 8 are independently selected from H and SO 2 NR 3 R 4 , wherein one of R 7 and R 8 is hydrogen and wherein NR 1 R 2 and NR 3 R 4 are independently 6- to 15-membered heterocycloalkyl containing one nitrogen in the ring,

or a pharmaceutically acceptable salt, ester, amide, stereoisomer or geometric isomer thereof.

2. A composition comprising a therapeutically effective amount of a compound of claim 1 in a pharmaceutically acceptable carrier.

3. The compound of claim 1 , wherein NR 1 R 2 and NR 3 R 4 are each piperidine substituted with 1 to 2 methyl substituents.

4. The compound of claim 1 , wherein NR 1 R 2 and NR 3 R 4 are each azepane.

5. A compound having the following formula:

or a pharmaceutically acceptable salt, ester, amide, stereoisomer or geometric isomer thereof.
