| abstract |
The invention relates to cyclodextrin derivatives of formula: (CF DRAWING IN BOPI) in which: - R1 represents a group derived from a steroid, - R2 represents an optionally substituted alkyl or aryl group, - R3 represents H or R2, - all the R4 represent OR2, or one of the R4 represents -NHCO (CH2) m CONHR1, These derivatives make it possible to ensure the transport of hydrophobic molecules for pharmaceutical or cosmetic applications, by forming organized systems in aqueous medium, alone or with phospholipids. |
