Disclosed herein are guanidinium containing compounds consisting of a core moiety with a plurality of side chains containing guanidinium groups. Such compounds have enhanced translocation across cellular membranes and epithelial tissues. The compounds may also have a therapeutic or other biologically active moiety attached so that these moieties may be effectively transported into a cell by the guanidinium containing compound.

[FR] L'invention concerne des composés contenant du guanidinium qui comprennent un fragment central présentant une pluralité de chaînes latérales contenant des groupes guanidinium. Lesdits composés permettent d'augmenter la translocation à travers des membranes cellulaires et des tissus épithéliaux. Un fragment thérapeutique ou un autre fragment actif sur le plan biologique est également lié auxdits composés de façon que les fragments soient transportés efficacement dans une cellule par le composé contenant du guanidinium.

The NHC-catalyzed thioesterification of aromatic or aliphatic aldehydes with a range of thiols was developed in the presence of a stoichiometric amount of an organic oxidant. Among the oxidants examined, phenazine was shown to give the best results in terms of chemical yield and compatibility with thiols.
