The present invention provides a method for forming compounds of Formula
HO—C(═O)R
1
—X—R
2
—X—R
1
—C(═O)—O—H
wherein compound (I) can be polymerized to provide a polymer that contains therapeutically active compounds. In the compounds of the invention, each R
1
is group that will provide the therapeutically active compound upon hydrolysis of the polymer; each X is independently an ester linkage or an amide linkage; and R
2
is a linking group.
本发明提供了一种形成化合物的方法,其
化学式为HO—C(═O)R1—X—R2—X—R1—C(═O)—O—H,其中化合物(I)可聚合以提供含有治疗活性化合物的聚合物。在本发明的化合物中,每个R1是在聚合物
水解后将提供治疗活性化合物的基团;每个X独立地是酯键或酰胺键;R2是一个连接基团。
