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 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)—.
一种胰岛素化合物与修饰基团偶联,公式如下:—X—R1—Y—PAG-Z—R2(公式VI),其中,X、Y和Z是独立选择的连接基团,每个都可以选择性地存在,当X存在时,通过共价键与胰岛素化合物偶联,R1或R2是低碳链基团,可以包括一个羰基基团,当R1是低碳链基团时,R2是一个帽基团,PAG是一个线性或支链碳链,包含一个或多个碱性乙二醇基团,并可以选择性地包含一个或多个来自—S—、—O—、—N—和—C(O)—的附加基团。
