Cooperative conveyance of basic active principles by amphiphilic acid molecules

An intermolecular association complex of an amphiphilic transporter and an active principle of the following general formula (I):

• wherein:
• S represents a carbohydrate fragment,
• R represents a hydrogen atom, a C1-C20, saturated or unsaturated, linear, branched, cyclic or aromatic hydrocarbon chain, optionally substituted by one or more fluorine atoms,
• X represents a C4-C9 alkyl, a C4-C9 alkenyl or a C4 -C9 alkynyl chain,
• Y− represents a carboxylate (—CO2−), sulfate (—O—SO3−), sulfonate (—SO3−), phosphate (—O—P(O)(ORa)O−), phosphonate (—O—P(O)RbO−) or phosphinate (—P(O)RbO−) group, with Ra representing a C1-C6 alkyl group and Rb representing a hydrogen atom or a C1-C6 alkyl group, and
• G represents an active principle comprising at least one primary, secondary or tertiary amine or guanidine functional group.
