β-nicotinamide mononucleotide is a product of the nicotinamide-phosphate ribosyltransferase (NAMPT) reaction. β-nicotinamide mononucleotide's actions include its role in cellular biochemical function, cardioprotection, diabetes, obesity-related complications, and Alzheimer's disease.

Nicotinamide riboside increases NAD[+] levels and activates SIRT1 and SIRT3, culminating in enhanced oxidative metabolism and protection against high fat diet-induced metabolic abnormalities.

Nicotinamide N-oxide (Nicotinamide 1-oxide) is recognized as an in vivo metabolite of nicotinamide which is a precurser of nicotinamide-adenine dinucleotide (NAD+) in animals. The enzyme that catalyzes the reduction of nicotinamide N-oxide to nicotinamide in the liver is xanthine oxidase.

Nicotinamide Riboside Triflate (SRT647 Triflate) is a natural NAD precursor that increases NAD levels, enhances oxidative metabolism and prevents obesity induced by a high-fat diet+, and can be used in studies of muscle atrophy.

Nicotinamide riboside chloride, also known as NR and SRT647, is a pyridine-nucleoside form of vitamin B3 that functions as a precursor to nicotinamide adenine dinucleotide or NAD+.

TRIA-662 (Nicotinamide Chloromethylate) is a niacin metabolite excreted via the urinary system.

Niacin (Nicotinic acid) is a water-soluble vitamin belonging to the vitamin B family, which occurs in many animal and plant tissues, with antihyperlipidemic activity. Niacin is converted to its active form niacinamide, which is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and its phosphate form, NADP.

6-Methylnicotinamide is a derivative of nicotinamide, an endogenous metabolite. 6-Methylnicotinamide is used to make co-crystals/salts. In the acute phase of cerebral hemorrhage (ICH), a sudden increase in 6-Methylnicotinamide exacerbates neurological damage.6-Methylnicotinamide can be used to make co-crystals/salts.6-Methylnicotinamide can be used to make co-crystals/salts.

N-Methylnicotinamide is one of the endogenous metabolites that ameliorates endothelial dysfunction.

Mallorepine may propably be an intermediate on the biosynthetic pathway from nicotinamide (II) to ricinine (III).

Phytic acid dipotassium salt is an endogenous metabolite that inhibits β-secretase 1 (BACE1).

(2S)-2',5,6',7-Tetrahydroxyflavanone can inhibit the lipid peroxide formation induced by adenosine diphosphate and reduced nicotinamide adenine dinucleotide phosphate in rat liver homogenate.

NADP disodium salt (Disodium NADP) is a nicotinamide adenine dinucleotide. NADP disodium salt is a key redox cofactor for electron transfer in the metabolism, serves as an electron carrier in a number of reactions, being alternately oxidized (NADP+) and reduced (NADPH).

Adenosine 5'-diphosphoribose sodium (ADP ribose sodium) is a metabolite of nicotinamide adenine nucleotide (NAD+), which is widely present in organisms.Adenosine 5'-diphosphoribose sodium (ADP ribose sodium) is a potent intracellular Ca2+-permeable cation TRPM2 channel activator. Adenosine 5'-diphosphoribose sodium (ADP ribose sodium) is a potent intracellular Ca2+ permeable cation TRPM2 channel activator that also induces autophagy.)

Ethionamide (2-ethylthioisonicotinamide) is a nicotinamide derivative, with antibacterial activity, used to treat tuberculosis. Although the exact mechanism of action of ethionamide is unknown, it may inhibit the synthesis of mycolic acid, a saturated fatty acid found in the bacterial cell wall, thereby inhibiting bacterial cell wall synthesis. This eventually leads to bacterial cell wall disruption and cell lysis. Ethionamide may be bacteriostatic or bactericidal in action, depending on the concentration of the drug at the site of infection and the susceptibility of the organism involved.
