Abstract
A tetravalent platinum compound-bicyclic double-bond-containing amphiphilic polymer prodrug, which has the structure as shown in formula (I): when m=1, represents when m=0, represents R represents —CHor —CHCH; Land Lindependently represent Cl, N, NO, and n is from 10 to 80. A preparation method of the prodrug is also disclosed. The method includes a step of reacting an axially dihydroxy-coordinated tetravalent platinum compound with a bicyclic double-bond-containing orthoester precursor. In addition, a nano-micelle formed by the prodrug and an application thereof are further disclosed. The amphiphilic polymer prodrug and the micelle formed therefrom have pH hypersensitivity and reduction dual responsiveness.
