The present invention pertains to certain aryl alkyl sulfonamides and derivatives thereof which, inter alia, inhibit osteoclast survival, formation, and/or activity; and/or inhibit bone resorption, and more particularly to compounds of the formula: [Insert formula] wherein: Ar1 is independently C5-20aryl (e.g., biphenyl, phenanthryl, fluorenyl, or carbazolyl, most preferably biphenyl), and is optionally substituted; RN is independently H, acyl, C5-20aryl-C1-7alkyl, C3-20 heterocyclyl, or C1-7alkyl, and is optionally substituted; Ralk is a C2-10 alkylene group, and is optionally substituted; and Q is independently -H or an organic group having from 1 to 30 atoms selected from carbon, nitrogen, oxygen, sulfur, phosphorus, fluorine, chlorine, bromine, and iodine (e.g., an oxy-type group, an amine-type group, etc.); and pharmaceutically acceptable salts, solvates, amides, esters, ethers, chemically protected forms, and prodrugs thereof. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit osteoclast survival, formation, and/or activity, and to inhibit conditions mediated by osteoclasts and/or characterised by bone resorption, in the treatment of bone disorders such as osteoporosis, rheumatoid arthritis, cancer associated bone disease, Paget's disease, and the like; and/or in the treatment of conditions associated with inflammation or activation of the immune system. |
