ABSTRACT:
Fluorinated derivatives useful as surfactants or in the transport of drug or markers, or in drug targeting, and preparations containing the derivatives, for medical, cosmetic and veterinary uses, having the formula: ##STR1## wherein R.sub.F is a fluorinated radical, X is a linear or branched alkylene, R.sup.1 is H or CH.sub.3, R.sup.2 is a radical having at least one OH group, R.sup.3 is a radical derived from an amino acid or a peptide, 1.ltoreq.n.ltoreq.50 and 0.ltoreq.m.ltoreq.200 with 0.2.ltoreq.n
+m.ltoreq.1.
These derivatives can be used as prodrugs or in formulating pharmaceutical, cosmetic and veterinary preparations, in biology and medicine, notably in compositions acting as carriers of oxygen and other gases, of contrast agents, or as carriers of substances used in therapy, or as carriers of markers.
