Lactate Dehydrogenase (LDH) is an enzyme that catalyzes the conversion of pyruvate, the end product of glycolysis, into lactate (and vice versa) with concomitant interconversion of NADH and NAD+. LDH is comprised of two major subunits, LDH-A and LDH-B, which can assemble into five different isoenzymes (LDH1, LDH2, LDH3, LDH4, and LDH5).

LDH-A is also known as the M subunit as it is predominantly found in skeletal muscle, and LDH-B is also known as the H subunit as it is predominantly found in the heart. LDH-A is a vital metabolic enzyme that is associated with cancer development, invasion, and metastasis. LDH-A is also the key player of the Warburg effect. LDH-A has been reported to correlate with clinicopathologic characteristics and survival outcome of multiple cancers. The inhibition of LDH-A has an anti-proliferative effect on primary breast tumors. LDH-B is a crucial glycolytic enzyme that catalyses conversion of lactate and NAD+ to pyruvate, NADH and H+. LDHB plays an important role in autophagy in cancer cells.

    Isomalt (Standard)
    Isomalt (Standard) is the analytical standard of Isomalt. This product is intended for research and analytical applications. Isomalt (Palatinitol), a well-tolerated, non-toxic polyol and a protein-stabilizing excipient, stabilizes lactate dehydrogenase (LDH) moderately during freeze-drying, and performs better during storage. Isomalt is traditionally used as a sweetening agent in the food industry and as a tabletting excipient for pharmaceutical purposes.

    Nifurtimox (Standard)
    		Inhibitor
    Nifurtimox (Standard) is the analytical standard of Nifurtimox. This product is intended for research and analytical applications. Nifurtimox, an antiprotozoal agent, which is generally used for the treatment of infections with Trypanosoma cruzi, has been used in the therapy of neuroblastoma. Nifurtimox affects enzyme activity of lactate dehydrogenase (LDH).

    NCATS-SM1441
    		Inhibitor
    NCATS-SM1441 (compound 52) is a lactate dehydrogenase (LDH) inhibitor (IC50=40 nM). By inhibiting the activity of LDH, NCATS-SM1441 is able to reduce the production of lactic acid in cancer cells, helping to slow or stop the proliferation of cancer cells. NCATS-SM1441 can be used to study cancer metabolism.

    Mancozeb (Standard)
    		Modulator
    Mancozeb (Standard) is the analytical standard of Mancozeb. This product is intended for research and analytical applications. Mancozeb is a widely used fungicide that is effective against fungal diseases in most cereals, vegetables, fruits and ornamental plants. In addition, Mancozeb can cause liver damage in mice by activating the Keap1/Nrf2 signaling pathway. Mancozeb upregulates lactate dehydrogenase and cytochrome c to alter cell metabolism and induce cell death. Mancozeb has reproductive toxicity and can induce apoptosis in ovarian cells.
