Background: Hypoxia-induced glycolysis represents a hallmark of colorectal cancer (CRC) progression and contributes significantly to therapeutic resistance. Curcumol, a natural sesquiterpenoid derived from Curcumae Rhizoma, has demonstrated promising anti-tumor properties. However, its impact on metabolic reprogramming under hypoxic conditions remains largely undefined. Objective: The objective of this study was to elucidate the potential of Curcumol in inhibiting glycolytic reprogramming and impede CRC progression via regulation of the VHL/HIF-1α signaling pathway. Methods: CRC cells and orthotopic mouse models were treated with Curcumol under chemically induced hypoxic conditions. Metabolic alterations were evaluated using Seahorse extracellular flux analysis, Western blot analysis, quantitative real-time PCR (qRT-PCR), immunohistochemistry (IHC) and co-immunoprecipitation (Co-IP). Functional validation of glycolysis and epithelial–mesenchymal transition (EMT) phenotypes was conducted through in vitro and in vivo assays. Results: Curcumol inhibited HIF-1α-mediated metabolic reprogramming by upregulating VHL expression, thereby promoting HIF-1α degradation. This effect led to the downregulation of key glycolytic genes (HK2, LDHA, and GLUT1), decreased glycolytic flux, and lactate production, ultimately suppressing CRC cell proliferation and invasion. The anti-tumor efficacy of Curcumol was validated in both in vitro and in vivo models. Moreover, Curcumol effectively reversed the hypoxia-induced epithelial–mesenchymal transition (EMT) phenotype, suggesting that its metabolic regulatory effects may contribute to reduced metastatic potential. Conclusions: Curcumol suppresses glycolysis and CRC progression by activating the VHL/HIF-1α signaling axis. These findings underscore the potential of Curcumol as a natural metabolic regulator capable of reversing tumor metabolic reprogramming, offering a promising therapeutic strategy for CRC treatment.
