CA 2294232

In accordance with the present invention, there are provided therapeutically effective compounds comprising an amphipathic carboxylate of the formula R- COOH, or a salt or an ester or amide of such compound, where R designates a saturated or unsaturated alkyl chain of 10-24 carbon atoms, one or more of which may be replaced by heteroatoms, where one or more of said carbon or heteroatom chain members optionally forms part of a ring, and where said chain is optionally substituted by a hydrocarbyl radical, heterocyclyl radical, lower alkoxy, hydroxyl-substituted lower alkyl, hydroxyl, carboxyl, halogen, phenyl or (hydroxy-, lower alkyl-, lower alkoxy-, lower alkenyl- or lower alkynyl)-substituted phenyl, C3-C7 cycloalkyl or (hydroxy-, lower alkyl-, lower alkoxy-, lower alkenyl- or lower alkynyl)-substituted C3-C7 cycloalkyl wherein said amphiphatic carboxylate is capable of being endogenously converted to its respective coenzyme A thioester.

Selon la présente invention, on décrit des composés efficaces sur le plan thérapeutique qui comprennent un carboxylate amphipathique correspondant à la formule R-COOH, ou un sel ou un amide de celui-ci. Dans cette formule, R représente une chaîne alkyle, saturée ou insaturée, possédant 10 à 24 atomes de carbone, dont un ou plusieurs peuvent être remplacés par des hétéroatomes, cette chaîne étant caractérisée en ce qu'un ou plusieurs des chaînons carbone ou hétéroatome forment éventuellement partie d'un noyau, et en ce qu'elle est éventuellement substituée par un radical hydrocarbyle, un radical hétérocyclyle, alcoxy inférieur, alkyle inférieur à substitution hydroxyle, hydroxyle, carboxyle, halogène, phényle ou phényle substitué par -hydroxy, alkyle inférieur, alcoxy inférieur, alcényle inférieur ou alcynyle inférieur-, cycloalkyle C¿3?-C¿7? ou cycloalkyle C¿3?-C¿7? substitué par -hydroxy, alkyle inférieur, alcoxy inférieur, alcényle inférieur ou alcynyle inférieur-, le carboxylate amphipathique pouvant être converti de manière endogène en son coenzyme A thioester correspondant.
