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.

selective Pd(0)-promoted cleavage of the C-terminal allyl ester; (vi) coupling of the C-terminal residue, i.e., H-Phe-SBzl, preactivated as a thioester; (vii) selective removal of the Nα-Trt and S-Xan protecting groups under very mild acid conditions; (viii) on-resin cyclization by native chemical ligation in an aqueous milieu; and (ix) final acidolyticcleavage of the cyclic peptidefrom the resin. The strategy
