Trimethylamine N-oxide (TMAO) is a gut microbiota-dependent metabolite derived from dietary choline, betaine, and carnitine. It induces inflammation by activating the ROS/NLRP3 inflammasome and promotes fibroblast differentiation through the activation of the TGF-β/Smad2 signaling pathway. TMAO is commonly used to induce cardiac fibrosis models.

Inosine (NSC-20262), an endogenous purine nucleoside produced by the catabolism of adenosine, is an agonist of adenosine receptors A1R and A2AR. Inosine has anti-inflammatory, immunomodulatory, antinociceptive and neuroprotective effects.

Rotenone is a natural plant-derived insecticide that acts as an inhibitor of mitochondrial electron transport chain complex I. It promotes the generation of mitochondrial reactive oxygen species, induces apoptosis, and is commonly used to establish Parkinson's disease models.

Uric acid is an important antioxidant that scavenges oxygen radicals and reactive oxygen species (such as singlet oxygen and peroxynitrite), inhibits lipid peroxidation, helps maintain stable blood pressure, and is the final product of purine metabolism. It is commonly used to induce hypertension models.

Liothyronine (Tresitope) is a synthetic and highly active thyroid hormone that acts as an effective agonist of TRα and TRβ (Ki = 2.33 nM for both hTRα and hTRβ). It activates the TRβ1 receptor, promotes the metabolism of carbohydrates, proteins, and fats, accelerates the oxidative processes in tissue cells, maintains basal metabolic rate, and supports normal growth and development. Liothyronine can be used to induce hyperthyroidism models.

Potassium oxonate is a uricase inhibitor that suppresses the phosphorylation of 5-FU to 5-fluorouridine-5'-monophosphate and is commonly used to establish hyperuricemia models.

Adenine hydrochloride is a purine nucleobase and a chemical component of DNA and RNA. It is involved in cellular respiration, protein synthesis, and plays an important role in energy metabolism through high-energy molecules such as ATP, NAD, and FAD. It can be used to induce hyperuricemia and chronic kidney injury models.

Glycerol is an important component of triglycerides (fats and oils) and phospholipids. It is widely used in the food industry as a sweetener, humectant, and in pharmaceutical formulations. Additionally, glycerol is used in sample preparation and gel formation for polyacrylamide gel electrophoresis and can be employed to induce acute kidney injury models.
