Abstract

The reprogramming of energy metabolism is considered to be one of the main characteristics of cancer. The development of therapeutic agents targeting glycolysis to alter aberrant glucose metabolism and restore oxidative phosphorylation has emerged as an effective approach for cancer therapy. In this way, we have developed a conjugate AlbA-DCA, which can induce a marked increase in intracellular ROS and alleviate the accumulation of lactic acid in TME. Meanwhile, AlbA-DCA selectively kills cancer cells and exhibits an excellent synergistic effect. Mechanism studies confirm that AlbA-DCA can induce apoptosis and ferroptosis. We also confirm that AlbA-DCA can remold the tumor immunosuppression microenvironment via eliminating M2-TAMs to inhibit both primary and distal tumor progression in a dual-4T1 tumor model in female BALB/c mice. As a result, rational design of natural saponin and PDK inhibitor to induce apoptosis-ferroptosis-M2-TAMs polarization for enhanced cancer therapy is a promising strategy, thus providing a new idea for cancer therapy.
