英文摘要To improve the therapeutic index of cisplatin (CDDP), we present here a new paradigm of drug-induced self-assembly by harnessing phosphato-platinum cornplexation. Specifically, we show that a phosphato-platinum cross-linked micelle (PpY/Pt) can be generated by using a block copolymer methoxy-poly(ethylene glycol)block-poly(L-phosphotyrosine) (mPEG-b-PpY). Coating of PpY/Pt with aR9-iRGD peptide by simple mixing affords a targeting micelle with near neutral-charged surface (iPpY/Pt). The micelles feature in well-controlled sizes below 50 nm and high, stability under physiological conditions, and can withstand various environmental stresses. Importantly, the micelles demonstrate on-demand drug release profiles in response to pathological cues such as high ATP concentration and acidic pH. In vitro, the micelles are efficiently internalized and almost equally potent compared to CDDP. Moreover, iPpY/Pt induce greater cytotoxicity than PpY/Pt in a 3D tumor spheroid model likely due to its deeper tumor penetration. In vivo, the micelles exhibit prolonged circulation half-lives, enhanced tumor accumulation, excellent tumor growth inhibition in a xenograft HeLa model and an orthotropic mammary 4T1 model, and improved safety profiles evidenced by the reduced nephrotoxicity. Together) this work demonstrates for the first time that phosphato-platinurn complexation can be exploited for effective delivery of CDDP, and suggests a paradigm shift of constructing nanosystems for other anticancer metallodrugs.
