An insulin compound coupled to a modifying moiety having a formula:
—X—R
1
—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 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)—, 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,与具有以下式的修饰基偶联:—X—R1—Y-PAG-Z-R(VI式)其中,X、Y和Z是独立选择的连接基,每个都可以选择存在,且当X存在时,它通过共价键与胰岛素化合物偶联,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是一个端基,PAG是一种线性或支链碳链,包括一个或多个碱基二醇基团,并且可以包括从以下组中选择的一个或多个附加基团:—S—、—O—、—N—和—C(O)—,其中修饰基最多有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。
