Glycolysis and oxidative phosphorylation are the two main metabolic pathways used by cells. However, the Warburg effect indicates that under aerobic conditions, tumor cells still prefer glycolysis over efficient oxidative phosphorylation to provide energy. Recently, the inhibition of tumor cell growth through metabolism pathways has received widespread attention. In this study, 2-deoxy-d-glucose (2DG), a glycolysis inhibitor, was introduced into a hydrogel system fabricated by forming covalent and hydrogen bonds with doxorubicin (DOX) and cellulose nanocrystals (CNC). The designed CNC-assembled hydrogel (CAH) system was self-assemble, injectable, and biocompatible. Moreover, DOX worked synergistically with 2DG, accomplishing multiple therapeutic functions against melanoma by targeting both chemical and metabolic pathways, including the inhibition of glycolysis and the enhancement of lipid peroxidation. Notably, compared to the control group, the ATP level of CNC/DOX/2DG decreased by 23% while NADPH level has decreased by 25% in B16F10 cells. Additionally, cleaved caspase-3 and caspase-7 levels were elevated following treatment in B16F10 cells. The CAH system can provide prolonged chemometabolic effects for combating melanoma.
