Particles of Hydrophobic-Chain-Modified Monosaccharides and Cyclodextrin

Particles comprising:

• at least one compound having the following formula:
• in which
• n represents 0 or 1;
• M represents a residue of a monosaccharide of which an OH is replaced by the group —X-(A-Y)n-Z and of which one or more —OH groups are optionally replaced by a group —OSO3H and/or of which a group —CH2—OH is optionally replaced by a group —COOH;
• X represents —O—, —S—, —NR1—, —OC(O)—, —SC(O)—, —N(R1)C(O)—, —OC(S)—, —SC(S)—, or —N(R1)C(S)—, the first atom of the groups being linked to M;
• A represents a linker, the linker being a (C1-C20)alkyl chain, optionally interrupted one or more times by one or more moieties selected from the group consisting of —O—, —S—, —NR2—, —C(O)—, and —C(S)—, and/or optionally substituted with one or more groups selected from the group consisting of a halogen atom, —NO2, —CN, —OR3, —SR4, and —NR5R6;
• Y represents —O—, —S—, —NR7—, —C(O)—, —C(S)—, —OC(O)—, —C(O)O—, —SC(O)—, —C(O)S—, —N(R7)C(O)—, —C(O)N(R7)—, —OC(S)—, —C(S)O—, —SC(S)—, —C(S)S—, —N(R7)C(S)—, or —C(S)N(R7)—;
• R1 to R7 represent, independently of each other, a hydrogen atom or a (C1-C6)alkyl group;
• and
• Z represents a saturated or unsaturated hydrocarbon chain comprising from 4 to 40 carbon atoms;
• at least one cyclodextrin.
