The invention relates to strontium salts of the sulfonic acids of formula (I): A-B-SO3H (I) in which: A is a group chosen from OH, NH2, SO3H and CO2H, and B is an arylene group or a linear or branched C1-C12 alkylene chain which is optionally substituted and in which one or more of the carbon atoms is optionally replaced with an oxygen or nitrogen atom or an SO2 group. The invention also relates to the use of new strontium salts derived from sulfonic acid in th treatment of osteoarthritis and osteoporosis.
L'invention concerne des sels de strontium des acides sulfoniques de formule (I) A-B-SO3H (I) dans laquelle: - A représente un groupement choisi parmi OH, NH2, SO3H et CO2H, - B représente un groupement arylène ou une chaîne alkylène linéaire ou ramifiée C1- C12 éventuellement substituée et dont un ou plusieurs des atomes de carbone est éventuellement remplacé par un atome d'oxygène, d'azote ou un groupement SO2.
