A Nucleoside Analogue Featuring a C3′-Stereogenic All-Carbon Quaternary Center as a Bioenergetic Disruptor of <i>KRAS</i>-Mutated Pancreatic Cancer Cells
A novel nucleoside analogue, LCB-2151, has been developed to induce cell death in <i>KRAS</i>-mutated pancreatic human cancer cell lines, which exhibit partial resistance to gemcitabine, a widely used anticancer drug. LCB-2151 disrupts the two primary sources of ATP production, namely, glycolysis and mitochondrial oxidative phosphorylation, reducing the bioenergetic capacity of these cells and inducing the formation of reactive oxygen species. Metabolomics and mitochondrial respiration analyses reveal that LCB-2151 inhibits key enzymes in glycolysis, the TCA cycle, and fatty acid β-oxidation. These findings highlight a coordinated mechanism driving bioenergetic disruption and cell death.
