PER (3,6-ANHYDRO) CYCLODEXTRINE DERIVATIVES, PRODUCTION AND USE THEREOF IN TRANSPORTING METAL ELEMENTS TO BIOLOGICAL TARGETS OR IN ORDER TO DECONTAMINATE BIOLOGICAL FLUIDS OR TARGETS

摘要

The invention relates to a derivative of per(3,6-anhydro)cyclodextrine of formulae (I) or (II) wherein at least one R1 represents a radical selected from peptides, proteins, lipids, oligo or polynucleotides and oligo or polysaccharides, biopolymers, and the other possible identical or different R1s represent a group selected from OH, OR 3, 0M, SH, SR3, OCOR3, NH2, NHR3, NR3R4, CONH2, CONHR3, CONR3R4, CN, CO0R3, OCH2COOH, COOH, OSO2R3, N3 and R3, wherein R3 and R4 are identical or different and represent a hydrocarbon, aliphatic or aromatic, saturated or unsaturated group which is optionally substituted by halogen atoms which can comprise one or several heteroatoms selected from 0, S and N, M represents a monovalent cation selected from alkaline metal cations; R2 s represent a single bond or a spacer group and n is equal to 6, 7 or 8. Said derivatives can be used to transport metal elements to biological targets or to decontaminate biological fluids or targets.
