and acidic pH, and thus alkylates antioxidant GSH through the release of quinone methide, thereby inhibiting an antioxidative system and increasing oxidation stress, and generates and accumulates reactive oxygen species (ROS) through the release of cinnamaldehyde, thereby promoting apoptosis, and thus the hybrid anticancer prodrug according to the present invention can be favorably used as an anticancer drug by creating a synergetic anticancer effect through double stimulus-response and sequential treatment action in a cancer cell-specific manner.

Self-immolative polymers degrade by an end-to-end depolymerisation mechanism in response to the cleavage of a stabilizing end-cap from the polymer terminus. Examples include homopolymers, mixed polymers including block copolymers, suitable for a variety of applications. A polyglyoxylate can be end-capped or capped with a linker as in a block copolymer.
