D-2-Hydroxyglutarate Dehydrogenase from Acidaminococcus fermentans, Recombinant
D-2-hydroxyglutarate (D2HG) level is significantly increased in metabolic diseases and various cancers such as acute myeloid leukemia. Studies suggest that the detection of D2HG serves as a biomarker assay related to IDH (isocitrate dehydrogenase) mutations. D2HGDH is a special NAD-dependent enzyme which reacts with D2HG specifically and converts D2HG to α-ketoglutarate. D2HGDH is a key enzyme to distinguish between two metabolites, D2HG and L-2-hydroxyglutarate (L2HG), during biomarker assays. Group: Enzymes.

D-3263
D-3263 is a TRPM8 agonist ( transient receptor potential melastatin member 8) with potential antineoplastic activity. The active ingredient in enteric-coated TRPM8 agonist D-3263 hydrochloride binds to and activates TRPM8, which may result in an increase in calcium and sodium entry; the disruption of calcium and sodium homeostasis; and the induction of cell death in TRPM8-expressing tumor cells. This agent may decrease dihydrotestosterone (DHT) levels, which may contribute to its inhibitory effects on prostate cancer and BPH. TRPM8 is a transmembrane calcium channel protein that is normally expressed in prostate cells and appears to be overexpressed in benign prostatic hyperplasia (BPH) and in prostate cancer.
