LID - 10.1515/znc-2023-0148 [doi] AB - Although chemotherapy is still the most preferred treatment for cancer, most chemotherapeutic agents target both cancer cells and healthy cells and cause serious side effects due to high toxicity. Improved drug delivery systems (DDSs), which enhance the efficacy of current chemotherapeutic drugs while reducing their toxicity, offer potential solutions to these challenges. Chitosan (CS) and its derivatives are biopolymers with biodegradable, biocompatible, and low-toxicity properties, and their structure allows for convenient chemical and mechanical modifications. In its role as a therapeutic agent, CS can impede the proliferation of tumor cells through the inhibition of angiogenesis and metastasis, as well as by triggering apoptosis. CS and its derivatives are also frequently preferred as DDSs due to their properties such as high drug-carrying capacity, polycationic structure, long-term circulation, and direct targeting of cancer cells. Various therapeutic agents linked to CS and its derivatives demonstrate potent anticancer effects with advantages such as reduced side effects compared to the original drugs, owing to factors like targeted distribution within cancer tissues and sustained release. This review emphasizes the utilization of CS and its derivatives, both as therapeutic agents and as carriers for established chemotherapeutic drugs.
