A drug-polymer conjugate, which is a copolymer of at least one monomer of formula (I) where: X may be the same or different at each occurrence and represents a terminal functional group comprising an alkyne or an azide; Q is independently selected at each occurrence and may be present or absent and when present, represents a linking group; R is selected from the group consisting of linear or branched hydrocarbon, optionally substituted aryl and optionally substituted heteroaryl; D is a releasable bicyclic prostaglandin; L is a linker group group; and at least one co-monomer of Formula III J-( Y1 –A)n, J represents a linking functional group, n is 2 to 8 preferably 3 to 8; Y1 comprises a polyether of formula (ORa)m wherein Ra is independently ethylene, propylene and butylene and m is from 1 to 300 (preferably 2 to 300) and the polyether is in chain with one or more groups which are preferably selected from one or more of optionally substituted straight or branched C1 to C10 alkylene, amino, ether, ester, amide, carbonate and carbamate; A may be the same or different at each occurrence and represents a group comprising a terminal functional group comprising an alkyne or an azide functionality, wherein said terminal functional group is complementary to the terminal functional group X of formula (I) providing triazole moieties from reaction of X and A.
一种药物-聚合物共轭物,其中是至少一个式(I)的单体的共聚物,其中:X在每次出现时可以相同也可以不同,表示包含炔烃或叠氮基团的末端官能团;Q在每次出现时独立选择,可以存在也可以不存在,当存在时,表示一个连接基团;R从由线性或支链烃烃基、可选择地取代的芳基和可选择地取代的杂环芳基组成的群体中选择;D是可释放的双环前列腺素;L是连接基团;以及至少一个式III J-(Y1-A)n的共单体,其中J表示连接官能团,n为2至8,最好为3至8;Y1包括一个式(ORa)m的聚醚,其中Ra独立地为乙烯、丙烯和丁烯,m为1至300(最好为2至300),聚醚与一个或多个基团链相连,这些基团最好选择自一个或多个可选择地取代的直链或支链C1至C10烷基、氨基、醚基、酯基、酰胺基、碳酸酯基和碳酸酯基;A在每次出现时可以相同也可以不同,表示包含一个末端官能团,该官能团包括一个包含炔烃或叠氮官能团的基团,其中所述末端官能团与式(I)的X的末端官能团互补,从X和A的反应中提供三唑基团。
