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.

Novel CE-phosphoramidites and CPG reagents have been synthesized from a serinol backbone. These reagents are useful to introduce functional groups or directly label oligonucleotides. The versatile serinol scaffold allows for labeling at any position (5′ or 3′ termini, or any internal position) during automated DNA synthesis. Multiple labels or functional groups can be achieved by repetitive coupling cycles. Optimal spacer arms and protected label moieties have been specially designed. Further, the natural 3-carbon atom internucleotide phosphate distance is retained when inserted internally.
maintaining the sequence specificity. Recently, an alternative approach, involving the replacement of sugar-containing nucleotides with acyclic nucleotideanalogs derived from serinol (8 ± 10) and phenyl- serinol (11), was developed; it allows the formation of an intramolecular H-bond between the amide NH of the acetamide tether and the phosphate O-atom to adopt a constrained conformation. These monomers
