      Description
      OverviewA cell-permeable, non-cytotoxic N-hydroxyindole (NHI) carboxylate that acts as a potent, reversible, and isoform selective inhibitor of lactic dehydrogenase (LDH) A/LDH-1. Inhibition appears to be competitive with respect to both pyruvate (Ki = 4.7 µM) and NADH (cofactor; Ki = 8.9 µM). Acts by occupying the whole substrate pocket and part of the cofactor pocket of LDH-A. Blocks the growth of various cancer cell lines by causing an arrest at G1 phase and inducing apoptosis (IC50 = 10.8, 10.6, 11.4, and 31.5 µM for A2780/cOHP, MSTO-211H, NIH-H28, and H630 cells, respectively). Exhibits enhanced anticancer activity under hypoxic conditions (GI50 = 0.90 µM/hypoxia vs. 16.3 µM/normoxia in LPC006 cultures) and strongly synergizes with gemcitabine (Cat. No. 504594).

      Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.

      Synonyms1-Hydroxy-6-phenyl-4-trifluoromethyl-1H-indole-2-carboxylic acid, Lactate Dehydrogenase A Inhibitor III, LDH-M Inhibitor III
      DescriptionA cell-permeable, noncytotoxic NHI (N-hydroxyindole) carboxylate that acts as an isoform A-selective LDH inhibitor (87% inhibition of hLDH-A4 vs 11% inhibition of hLDH-B4 at 125 µM; [NADH] = 25 µM & [pyruvate] = 2 mM) in a competitive manner with respect to both NADH (Ki = 8.9 µM; [pyruvate] = 2 mM) and pyruvate (Ki = 4.7 µM; [NADH] = 200 µM). Shown to effectively inhibit de novo D-[1,6-13C2] glucose-derived lactate production in HeLa cultures (80% and <5% of control Lac/Glu ratio in 12 h, respectively, with 400 and 500 µM inhibitor) and exhibit enhanced anticancer activity under hypoxic conditions (GI50 by SRB assays = 0.90 µM/hypoxia vs. 16.3 µM/normoxia in LPC006 cultures), while diplaying little antiproliferation activity toward non-tumorigenic hTERT-HPNE (ductal pancreatic) and Hs27 (skin fibroblast) even at concentrations as high as 100 µM;.
