An insulin compound coupled to a modifying moiety having a formula:
—X—R1—Y-PAG-Z—R (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 R1 or R2 is is a lower alkyl, optionally including a carbonyl group, and when R1 is a lower alkyl, R2 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)—, and
where the modifying moiety has a maximum number of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 heavy atoms.
一种胰岛素化合物,其与具有以下式子的修饰基偶联:—X—R1—Y-PAG-Z—R (式子VI)
其中,X、Y和Z是独立选择的连接基,每个连接基都可以选择性地存在,当X存在时,与胰岛素化合物通过共价键耦合;R1或R2是较低的烷基,可以包括一个羰基基团,当R1是较低的烷基时,R2是一个帽基;PAG是线性或支链碳链,包含一个或多个碱基二醇基团,并且可以选择性地包含从—S—、—O—、—N—和—C(O)—中选择的一个或多个额外基团;修饰基最大有3、4、5、6、7、8、9、10、11、12、13、14、15、16、17、18、19、20、21、22、23、24或25个重原子。
