Dual-pH sensitive drug carrier system and preparation method thereof

The invention discloses a dual-pH sensitive drug carrier system which is prepared by the following steps of modifying the surface of H-MnO2 encapsulating adriamycin (DOX) as an anticancer drug with a"valve" chitosan (CHI) to block a pore channel; and then, binding benzaldehyde terminated polyethylene glycol (mPEG-CHO) to CHI through an imine bond to prepare DOX@H-MnO2-CHI-PEG as the dual-pH sensitive drug carrier system. For the drug carrier system, under the protection of mPEG, the carrier can be "invisible" under the normal physiological conditios (with a pH value being 7.4), so that non-specific phagocytosis of normal cells can be avoided, and circulation time of the carrier in vivo can be prolonged; while in a tumor tissue less-acidic environment (with the pH value being 6.5), the imine bond binding the mPEG to the CHI is hydrolytically cleaved, the mPEG as a protective layer falls off, and the positively charged CHI is exposed, so that acid activation is realized, uptake of tumorcells to the carrier is promoted, and the situation that the carrier enters cancer cells is facilitated; and under a more acid environment (with the pH value being 5.5) in the cancer cells, H-MnO2 can further degrade, so that the DOX is released to kill the cancer cells.
