An insulin compound coupled to a modifying moiety having a formula:
—X—R
1
—Y-PAG-Z—R
2
(Formula VI)
where,
X, Y and Z are independently selected linking groups and each is optionally present, and X, when present, is coupled to the insulin compound by a covalent bond,
either R
1
or R
2
is is a lower alkyl, optionally including a carbonyl group, and when R
1
is a lower alkyl, R
2
is a capping group, and
PAG is a linear or branched carbon chain incorporating one or more alkalene glycol moieties, and optionally incorporating one or more additional moieties selected from the group consisting of —S—, —O—, —N—, and —C(O)—.
