Hydrophilic transportable N-linked glycosyl dopaminergic prodrug compounds
according to FORMULA V and methods of their use, ##STR00001## wherein,
Ring 1 comprises an aryl or heteroaryl ring having 4 to 8 carbon atoms,
among which atoms are counted "X" and "Y"; each of X and Y is optional;
X, when present is either --C(R.sub.1).sub.2-- or --C(R.sub.1).sub.2--;
Y, when present, is either --CH.sub.2-- or --CH.sub.2--CH.sub.2--; z,
R.sub.5 and R.sub.5' are optional, and when present z, R.sub.5 and
R.sub.5' together form a lower alkyl or a substituted lower alkyl moiety;
N is part of either an amine or an amide linkage; E is a saccharide which
forms a linkage with N through a single bond from a carbon or oxygen atom
thereof; R.sub.1 and R.sub.4 are selected form the group consisting of
hydrogen, hydroxyl, halogen, halo-lower alkyl, alkoxyl, alkoxyl-lower
alkyl, halo-alkoxy, thioamido, amidosulfonyl, alkoxylcarbonyl,
carboxamide, aminocarbonyl, and alkylamino-carbonyl; R.sub.2 and R.sub.3
are hydroxyl; R.sub.5 and R.sub.6, when present, are selected from the
group consisting of hydrogen, hydroxyl, alkoxyl, carbonyl,
alkoxylcarbonyl, aminocarbonyl, alkylamino-carbonyl and
dialkylamino-carbonyl; and, R.sub.6 and R.sub.6' are selected from the
group consisting of hydrogen, hydroxyl, alkoxyl, carboxyl,
alkoxylcarbonyl, aminocarbonyl, alkylamino-carbonyl and
dialylamino-carbonyl, with the proviso that Ring 1 is capable of binding
to any of: a dopaminergic receptor selected from the group consisting of
a D1 receptor and a D5 receptor; a DAT transporter; a VMAT transporter;
and, with the proviso that E is capable of binding to a GLUT transporter
selected from the group consisting of a GLUT1 receptor and a GLUT3
receptor.
