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.

The activity of some representative enzymes has been tested on a series of fullerene derivatives. When the functional group that interacts with the enzyme active site is close to the fullerene spheroid the reaction rates slow down, whereas relatively fast reactions are observed for reaction centres spatially distant from the carbon sphere.

Disclosed are conjugate molecules formed from an active agent which is linked to a cannabinoid moiety through a specified linker having ester and amide end groups. The active agent can be a COX-2 inhibitor moiety, and the cannabinoid moiety can be a cannabidiol moiety. These conjugate molecules are contemplated to potentially be effective in the treatment of medical conditions.

Novel acid-sensitive compounds comprising a cyclic ortho-ester that is acid-sensitive, and their salts, and comprising at least one hydrophilic substituent. These compounds are useful, for example, 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.
