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.

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.

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.

L-Arginine (L-Arg) is a substrate of endothelial nitric oxide synthase (eNOS). L-Arginine is transported to vascular smooth muscle cells via a family of cationic amino acid transporters and is metabolized to nitric oxide, polyamines, or L-proline. L-Arginine is a potent 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.

Eleutheroside E has anti-inflammatory effects by inhibiting NF-κB activities. Eleutheroside E significantly decreases the inflammatory cell infiltration, pannus formation, cartilage damage, bone erosion of CIA mice, the generation of TNF-α and IL-6, the m

6-Hydroxymelatonin is the main active metabolite and endogenous metabolite of Melatonin via CYP1A2, an agonist of MT2 receptor with antioxidant and neuroprotective effects, and effectively reduces KCN-induced lipid peroxidation and superoxide anion production.

Pi-Methylimidazoleacetic acid, considered a potential neurotoxin, targets the nervous system and may pose significant health risks when absorbed or metabolized within biological systems.

2,2-Dimethylsuccinic acid (2,2-DMSA) is a gut-metabolized biomarker.

Tributyrin (Glyceryl tributyrate), a neutral short-chain fatty acid triglyceride, is a stable and rapidly absorbed prodrug of Butyric Acid. It diffuses through biological membranes and is metabolized by intracellular lipases, releasing effective butyrate directly into cells in vivo, exhibiting potent proapoptotic, antiproliferative, and differentiation-inducing effects.

Epmedin C (Baohuoside-VI) was metabolized via desugarization, dehydrogenation, hydrogenation, dehydroxylation, hydroxylation, demethylation and glucuronidation pathways in vivo. It has potential activity against osteoporosis by stimulating osteoblasts.

Potassium 1H-indol-3-yl sulfate (Potassium 3-indoxyl sulfate) is an agonist for the human Aryl Hydrocarbon Receptor (AhR), a key regulator of immune-inflammatory conditions. A metabolite of tryptophan derived from dietary protein, it is produced by intestinal bacteria and metabolized in the liver. In chronic kidney disease patients with impaired renal function, it accumulates in serum as a uremic toxin, inducing oxidative stress and accelerating disease progression. At 250 μM, it activates NF-Κb, promoting TGF-β1 and Smad3 expression in rat proximal tubular cells, which is associated with profibrotic activity.

Calcifediol (U 32070E) is a naturally occurring product that is metabolized in the liver from vitamin D3, a VDR ligand. Calcifediol is indicated for use as a vitamin supplement for all patients with vitamin D deficiency.

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.

Oxalic acid (Standard) is the standard substance of Oxalic acid, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Oxalic acid (Ethanedioic acid) 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.

p-Cresol (Standard) is the standard substance of p-Cresol, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. P-cresol is a partially lipophilic compound that strongly binds to plasma proteins (approximately 100%) under normal conditions. Paraformaldehyde is metabolized through conjugation, mainly through sulfation and glucuronidation, but the unbound paraformaldehyde is at least partially excreted through urine.

(±)-Enterodiol, the racemate of Enterodiol, is metabolized from lignans found in whole-grain cereals, nuts, legumes, flaxseed, and vegetables by human intestinal bacteria. This compound exhibits apoptotic effects in colorectal cancer (CRC) cells and has been identified to possess anti-cancer activities [1] [2].

1β-Hydroxydeoxycholic acid (1β-OH-DCA), recognized as a secondary bile acid, serves as a biomarker for CYP3A. This compound is metabolized from deoxycholic acid specifically by CYP3A4 and CYP3A7 through recombinant human CYP450 enzymes [1].

1,2-Dihydroxynaphthalene, an intermediate isolated from naphthalene metabolism, is confirmed as a precursor to the formation of naphthoquinone. This compound can be further metabolized by certain bacteria (such as Pseudomonas spp.) into compounds like coumarin and salicylic acid.
