Abstract: The present invention pertains to compounds of the following formula (wherein RP, r, q, RN, Ralk, and Q are as defined herein) and compositions comprising those compounds. The compounds may be used to inhibit osteoclast survival, formation, and/or activity; 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/or in the treatment of conditions associated with inflammation or activation of the immune system.

Abstract: 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: 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, C3-20heterocyclyl, or C1-7alkyl, and is optionally substituted; Ralk is a C2-10alkylene 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.
