S6871 Sodium oxamate Sodium oxamate (SO, Aminooxoacetic acid, Oxamic acid) is an inhibitor of lactate dehydrogenase (LDH) that specificly inhibits LDH‑A. This compound induces G2/M cell cycle arrest via downregulation of the CDK1/cyclin B1 pathway and promotes apoptosis through enhancement of mitochondrial ROS generation.

E4772 LDHA-IN-3 LDHA-IN-3, a selenobenzene derivative, is a potent noncompetitive inhibitor of Lactate Dehydrogenase A (LDHA), with an IC50 of 145.2 nM. It exhibits significant anti-tumor activity, effectively reducing LDHA activity and lactate production under both normoxic and hypoxic conditions. It also induces mitochondria-mediated apoptosis through the generation of reactive oxygen species.
S3143 Pyruvic acid

Pyruvic acid (Acetylformic acid) is an important organic chemical intermediate that plays a role in cardiomyocyte pathophysiology and therapy. This compound markedly increases the level of lactate dehydrogenase (LDH) and creatine kinase (CK) and reduces the level of Ca2+Mg2+-ATPase and Na+K+-ATPase.
E4635New AXKO-0046 hydrochloride AXKO-0046 hydrochloride is an indole-derived, selective LDHB inhibitor that acts through an uncompetitive mechanism, with an EC50 of 42 nM. It binds an allosteric site distinct from the catalytic active site and shows selectivity over LDHA.
E3731 Chinese Gallnut Extract Chinese Gallnut Extract is obtained from Melaphis chinensis gallnut, which is the most potent inhibitor of human Lactate dehydrogenase (LDH)-A in the high-throughput screening study of 905 natural products.
E6631New Oxamic acid Oxamic acid (Oxamate) is a classical inhibitor of lactate dehydrogenase‑A (LDH‑A) that competitively blocks the conversion of pyruvate to lactate. It also induces G2/M arrest and apoptosis, and increases radiosensitivity in nasopharyngeal carcinoma cells.
