It is metabolized to glycyrrhetinic acid, which inhibits 11-β-hydroxysteroid dehydrogenase and other enzymes involved in the metabolism of corticosteroids. Therefore, glycyrrhizic acid, the main and sweet component of licorice, has been studied for its ability to cause hypermineralocorticoidism with potassium loss and sodium retention, edema, increased blood pressure, as well as inhibited the renin-angiotensin-aldosterone system.

L-Arginine hydrochloride serve as substrates and nitrogen donors for endothelial nitric oxide synthase (eNOS) to produce nitric oxide (NO). They are transported into vascular smooth muscle cells via cationic amino acid transporters, where they are metabolized into NO, polyamines, or L-proline. As effective vasodilators, they are commonly used to induce experimental acute pancreatitis models.

Tinidazole (CP12574)a is a 5-nitroimidazole derivative with the antiprotozoal property. Although the mechanism of action has not been fully elucidated, it has been suggested that tinidazole is metabolized and yields nitrite anions and metronidazole. Metronidazole's nitro group, in turn, is reduced via the parasite ferredoxin, thereby generating a series of free nitro radicals including nitro anions. Toxicity is achieved via depletion of sulfhydryl groups and DNA strand breaks with multiple hits having an additive effect and ultimately leading to cell death.

Diacerein (Fisiodar) is a prodrug which is metabolized to rhein. It is currently approved in France for the treatment of osteoarthritis although the use of diacerein is restricted due to the side effects including sevre diarrhea [L780]. Diacerein is under investigation for the treatment of Insulin Resistance, Diabetes Mellitus (Type 2), and Diabetes-Related Complications.

Capecitabine (Capecitibine) is a fluoropyrimidine carbamate belonging to the class of antineoplastic agents called antimetabolites. As a prodrug, capecitabine is selectively activated by tumor cells to its cytotoxic moiety, 5-fluorouracil (5-FU); subsequently, 5-FU is metabolized to two active metabolites, 5-fluoro-2-deoxyuridine monophosphate (FdUMP) and 5-fluorouridine triphosphate (FUTP) by both tumor cells and normal cells. FdUMP inhibits DNA synthesis and cell division by reducing normal thymidine production, while FUTP inhibits RNA and protein synthesis by competing with uridine triphosphate for incorporation into the RNA strand.

L-Histidine (L-(-)-Histidine) is a semi-essential amino acid (children should obtain it from food) needed in humans for growth and tissue repair, L-Histidine is important for maintenance of myelin sheaths that protect nerve cells and is metabolized to the neurotransmitter histamine. Histamines play many roles in immunity, gastric secretion, and sexual functions. L-Histidine is also required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals.

Oxalic acid is a strong dicarboxylic acid occurring in many plants. Oxalic acid is produced in the body by metabolism of glyoxylic acid or ascorbic acid.

Thioacetamide (TAA) is an indirect hepatotoxin commonly used to induce experimental liver injury. It is metabolized by CYP2E1 into reactive metabolites that covalently bind to proteins and lipids, leading to oxidative stress and centrilobular necrosis, hepatocyte death, and M1/M2 macrophage-dominated inflammation. TAA is widely used to establish models of chronic liver fibrosis, hepatic encephalopathy, and liver cancer.

L-Arginine (L-Arg) is a substrate for endothelial nitric oxide synthase (eNOS), participating in protein synthesis, polyamine production, and cellular signaling regulation. L-Arginine is transported into vascular smooth muscle cells via the cationic amino acid transporter family and metabolized into nitric oxide, polyamines, or L-proline. L-Arginine is an effective vasodilator and can be used to induce experimental acute pancreatitis.

Potassium 1-carboxyvinyl hydrogenphosphate (PEP-K) is involved in glycolysis and gluconeogeneis. In glycolysis, PEP is metabolized by Pyruvate Kinase to yield pyruvate. In plants, PEP is involved in the formation of aromatic amino acids as well as in the carbon fixation pathway.

Oxalic acid dihydrate (Ethanedioic acid dihydrate) is a strong dicarboxylic acid occurring in many plants and vegetables. It is produced in the body by metabolism of glyoxylic acid or ascorbic acid. It is not metabolized but excreted in the urine. It is used as an analytical reagent and general reducing agent.

Cholestenone is an intermediate oxidation product of cholesterol that is metabolized primarily in the liver. It can cause long-term defects in cell function. It is highly mobile in membranes and affects cholesterol turnover and efflux.

2-Phenylethylamine hydrochloride (benzeneethanamine hydrochloride) acts as neuromodulator in the central nervous system. It stimulates the release of norepinephrine and dopamine and is metabolized by monoamine oxidases as well as other enzymes.

Acetohexamide (Acetohexamid) is an intermediate-acting, first-generation sulfonylurea with hypoglycemic activity. It inhibits sulfonylurea receptor 1 (SUR1) linked to the inwardly rectifying potassium channel (KIR6.2) with Ki values of 22.9 and 14.2 μM in HEK293 cells transfected with the human receptor and in rat brain, respectively. Acetohexamide is metabolized in the liver to its active metabolite hydroxyhexamide.

4-Hydroxyatomoxetine-D3 is a deuterium labeled 4-Hydroxyatomoxetine. 4-Hydroxyatomoxetine (T10145) is an active metabolite of Atomoxetine. 4-Hydroxyatomoxetine (T10145) is metabolized by CYP2D6. Atomoxetine is a noradrenaline reuptake inhibitor.
