Novel acid-sensitive compounds comprising at least one hydrophilic substituent and a cyclic ortho-ester which is acid-sensitive, and their salts. These compounds are useful for forming conjugates (liposomes, complexes, nanoparticles and the like) with biologically active substances and releasing them into cellular tissues or compartments whose pH is acidic, or as nonionic surfactant for stabilizing particles encapsulating a biologically active substance and then destabilizing them in acid medium, or alternatively as a vector covalently linked to a therapeutic molecule so as to release said therapeutic molecule into the cellular tissues or compartments whose pH is acidic.

Nouveaux composés acidosensibles comprenant au moins un substituant hydrophile et un orthoester cyclique qui est acidosensible, et leurs sels. Ces composés sont utiles soit pour former des conjugués (liposomes, complexes, nanoparticules ...) avec des substances biologiquement actives et les libérer dans des tissus ou compartiments cellulaires dont le pH est acide, soit en tant qu'agent de surface non-ionique pour stabiliser des particules encapsulant une substance biologiquement active puis les déstabiliser en milieu acide, ou encore en tant que vecteur lié covalemment à une molécule thérapeutique afin de libérer ladite molécule thérapeutique dans les tissus ou compartiments cellulaires dont le pH est acide.
