PDHK1-IN-1 (compound 17) is a selective inhibitor of PDHK1 with an IC50 value of 1.5 μM, demonstrating anticancer properties. PDHK1 negatively regulates the pyruvate dehydrogenase complex (PDC), thereby restricting the tricarboxylic acid (TCA) cycle and oxidative phosphorylation. Overexpression of PDHK1 leads to increased reliance on glycolysis (Warburg effect). PDHK1-IN-1 inhibits phosphorylation at the PDHK1 recognition site PDC E1α Ser232 and also suppresses phosphorylation of Ser293.

Tetradifon is a broad-spectrum organochlorine acaricide insecticide and a potent inhibitor of the mitochondrial oligomycin sensitivity conferring protein (OSCP)，a subunit of ATP synthase. Tetradifon is utilized for controlling a variety of mite pests and inhibiting energy-related mitochondrial activities including ADP-stimulated respiration and ATPase activity with an IC50 range of 4.5-27 nmoL/mg mitochondrial protein; it exerts oligomycin-like effects by inhibiting oxidative phosphorylation, inducing significant oxidative stress, and interfering with bone metabolism, making it a compound of interest for researching mitochondrial function, bone remodeling mechanisms, and nephrotoxicity.

Calcium 2-hydroxypropanoate (pentahydrate) acts as an activator of the hydroxyl-carboxylic acid receptor 1 (HCAR1) and serves as an epigenetic regulator that induces lysine residue lactylation. This compound, a glycolysis end product, bridges the gap between glycolysis and oxidative phosphorylation and functions as a tumor metabolite with immunoprotective effects of lactate in antitumor immunity.

Oligomycin is a macrolide antibiotic produced by Streptomyces. Oligomycin is commonly used to study mitochondrial function and cellular energy metabolism and has antifungal and antitumor activities.
