NAD+ (β-Nicotinamide Adenine Dinucleotide) is a coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage.

(S)-Malic acid ((S)-2-Hydroxysuccinic acid) is a tart-tasting organic dicarboxylic acid found in many sour foods, such as apples, and contributes to the sourness of green apples and tartness of wine, although its concentration decreases with fruit ripeness (wikipedia). In its ionized form, it is called malate, an intermediate in the TCA cycle alongside fumarate, and can be formed from pyruvate through anaplerotic reactions. In humans, malic acid is derived from food sources and synthesized in the body via the citric acid cycle in mitochondria, playing a crucial role in energy production under both aerobic and anaerobic conditions. Under aerobic conditions, malate is oxidized to oxaloacetate, providing reducing equivalents via the malate-aspartate redox shuttle, while during anaerobic conditions, its simultaneous reduction to succinate and oxidation to oxaloacetate removes excess reducing equivalents, reversing hypoxia's inhibition of glycolysis and energy production. Studies on rats have shown that tissue malate depletes following exhaustive physical activity, suggesting that malic acid deficiency may cause physical exhaustion. Administering malic acid to rats has been shown to elevate mitochondrial malate, increasing mitochondrial respiration and energy production.

Cholesteryl linoleate is the major cholesteryl ester in LDL and atherosclerotic lesions. It is present in LDL as a cholesteryl ester that is oxidized to form cholesteryl linoleate hydroperoxides using LDL receptor-associated proteins that are transferred to the plasma membranes of macrophages and CHO cells expressing 15-lipoxygenase.

NADH disodium salt (Disodium NADH) hydrate is the reduced form of nicotinamide adenine dinucleotide (NAD) that can donate electrons in a reducing reaction, becoming oxidized to produce NAD+. Various enzymes utilize NADH disodium salt hydrate plus H+ to reduce substrates, generating NAD+ and the reduced product.

Rifamycin S is a potent DNA-dependent RNA polymerase inhibitor,is a quinone and an antibiotic agnet against Gram-positive bacteria

Isorhamnetin (3-methylquercetin) is the methylated metabolite of quercetin. Quercetin is an important dietary flavonoid with in vitro antioxidant activity. Isorhamnetin prevents endothelial cell injuries from oxidized LDL via inhibition of lectin-like ox-LDL receptor-1 upregulation, interference of ox-LDL-mediated intracellular signaling pathway (p38MAPK activation, NF-kappaB nuclear translocation, eNOS expression) and the antioxidant activity of isorhamnetin. Isorhamnetin prevents endothelial dysfunction, superoxide production, and overexpression of p47phox induced by angiotensin II. Isorhamnetin appears to be a potent drug against esophageal cancer due to it's in vitro potential to not only inhibit proliferation but also induce apoptosis of Eca-109 cells.

Cytochalasin A, a cell-permeable fungal toxin and oxidized derivative of cytochalasin B, is an inhibitor of HIV-1 protease (IC50 = 3 μM). It inhibits actin polymerization, interferes with microtubule assembly by reacting with sulfhydryl groups, and serves as an antibiotic and bactericidal active agent.
