LDHA PDKs-IN-1 (compound 20e) is a highly effective dual inhibitor of PDKs and LDHA, displaying IC50 values of 0.8 μM and 0.15 μM, respectively. It significantly suppresses A549 cell proliferation (EC50 = 13.2 μM), reduces lactate formation, and enhances oxygen consumption. This compound holds great promise for cancer research [1].
