摘要
用聚乙二醇(PEG)修饰异黄酮类化合物(1)的侧链,并采用不同氨基酸做连接臂,合成了聚乙二醇-异黄酮复合物——聚乙二醇-异黄酮酯前药(6),其结构经1H NMR和IR表征。在磷酸缓冲溶液中,1能在10 h内释放完全;6的载药量有待进一步提高。
Poly (ethylene glycol) -isoflavone complexes, poly (ethylene glycol) -isoflavone ester prodrugs (6), were synthesized by modifying side chain radical of isoflavone ( 1 ) with PEG using different amino acids as the join-arm between 1 and PEG. The structures of 6 were confirmed by ^1H NMR and IR. The results showed that 1 was released completely from 6 in 10 h in phosphonic acid buffer solution. The loading amout of 1 on 6, which was comparatively lower, need to be further improved.
