N-Desbutyl dronedarone is an active metabolite of the antiarrhythmic agent dronedarone .1,2,3It is formed from dronedarone by cytochrome P450s (CYPs) and monoamine oxidase (MAO) in human hepatocyte preparations.4N-Desbutyl dronedarone inhibits the binding of 3,3',5-triiodo-L-thyronine to the thyroid hormone receptors TRα1and TRβ1(IC50s = 59 and 280 μM for the chicken and human receptors, respectively).1It inhibits CYP2J2-mediated formation of 14,15-EET from arachidonic acid and soluble epoxide hydrolase-mediated formation of 14,15-DHET from 14,15-EET (IC50s = 1.59 and 2.73 μM, respectively, in cell-free assays).2N-Desbutyl dronedarone decreases intracellular ATP levels in H9c2 rat cardiomyocytes (IC50= 1.07 μM) and inhibits mitochondrial complex I, also known as NADH dehydrogenase, and mitochondrial complex II, also known as succinate dehydrogenase, activities in isolated rat heart mitochondria (IC50s = 11.94 and 24.54 μM, respectively).3 1.Van Beeren, H.C., Jong, W.M.C., Kaptein, E., et al.Dronerarone acts as a selective inhibitor of 3,5,3'-triiodothyronine binding to thyroid hormone receptor-α1: in vitro and in vivo evidenceEndocrinology144(2)552-558(2003) 2.Karkhanis, A., Tram, N.D.T., and Chan, E.C.Y.Effects of dronedarone, amiodarone and their active metabolites on sequential metabolism of arachidonic acid to epoxyeicosatrienoic and dihydroxyeicosatrienoic acidsBiochem.

IM-156 acetate, an activator of NADH dehydrogenase (IC50=2.2 μM) and AMP-activated protein kinase alpha (AMPKα), is an orally available and bioavailable inhibitor of mitochondrial oxidative phosphorylation (OxPhos).IM-156 acetate increases AMPKα activity and inhibits chlorhexadiene-induced peritoneal fibrosis and inhibit tumor growth in rats .

sn-Glycerol 3-phosphate lithium is synthesized via the cytosolic glycerol 3-phosphate dehydrogenase pathway, involving the conversion of dihydroxyacetone phosphate to sn-Glycerol 3-phosphate using NADH generated during glycolysis.

(R)-(-)-1,2-Propanediol is the (R)-enantiomer of 1,2-Propanediol, derived from glucose via NADH-linked glycerol dehydrogenase gene expression in Escherichia coli.

Proguanil hydrochloride (Chloroquanil) is a biguanide compound which metabolizes in the body to form cycloguanil, an anti-malaria agent.Upon hydrolysis, Proguanil hydrochloride is converted to its active cyclic triazine metabolite, cycloguanil, by a cytochrome P450 dependent reaction. Cycloguanil selectively inhibits the bifunctional dihydrofolate reductase-thymidylate synthase of plasmodium parasite, thereby disrupting deoxythymidylate synthesis and ultimately blocking DNA and protein synthesis in the parasite.

Pyridaben is a METI acaricide that inhibits mitochondrial electron transport at complex I (METI; Ki = 0.36 nmol mg protein in rat brain mitochondria).

CBR-3465 is an inhibitor of mycobacterium tuberculosis (Mtb) type II NADH dehydrogenase. The MIC of CBR-3465 against Mtb is 0.16 μM [1].

Beta-Galactose dehydrogenase catalyzes the conversion of galactose into galactonolactone, simultaneously reducing NAD to fluorescent NADH. This enzyme is useful for the determination of galactose [1].

Glucose dehydrogenase (GDH) is an oxidoreductase enzyme that facilitates the oxidation of β-D-glucose into β-D-glucono-1,5-lactone, while concurrently reducing cofactor NADP+ to NADPH, and to a lesser degree, NAD+ to NADH. It can utilize both NAD+ and NADP+ as cofactors and serves in the regeneration of NADH and NADPH [1] [2].

Glyceraldehyde phosphate dehydrogenase, targeted by anti-thymocyte and anti-apoptotic agents, catalyzes the oxidation of reduced nicotinamide adenine dinucleotide (NADH) by perhydroxyl radicals [1] [2].

HP661, a selective inhibitor of mitochondrial complex I (NADH dehydrogenase), impedes complex I activity by 77.6% at 1 µM, demonstrating lesser inhibition towards complex III (28.1%) and no inhibitory effects on complexes II and IV. It notably decreases the viability of human lung cancer cells—H460, NCI H441, and trametinib-resistant A549 cells (IC50s = 10.6, 29.7, and 15.1 nM, respectively)—which exhibit high levels of oxidative phosphorylation. In contrast, it shows minimal activity against NCI H358 lung cancer cells and non-cancerous HPNE and MRC-5 cells (IC50s = >10,000 nM for both), which have lower oxidative phosphorylation levels. Furthermore, in an H460 mouse xenograft model, HP661 at a dose of 30 mg/kg twice daily significantly reduces tumor volume and enhances the tumor-growth inhibitory effects of trametinib.
