Abstract
Mono (6-amino-6-deoxy)cyclodextrin derivatives substituted in the 6-position by an .alpha.-amino acid residue. These derivatives correspond to the following general formula: ##STR1## in which: CD represents .alpha.-, .beta.- or .gamma.-cyclodextrin, PA1 n is 0 or 1, and PA1 Z represents a divalent radical chosen from: PA2 (i) --CH.sub.2 PA2 (ii) --O--CH.sub.2-- PA2 (iii) --S--CH.sub.2 --, ##STR2## and (v) --O--C.sub.6 H.sub.4 --CH.sub.2 --. These derivatives find an application in the formation of inclusion complexes of active substances and can be used in various fields, in particular in cosmetics, in dermatology and in pharmacology.
