3-(3,4-dimethoxyphenyl)prop-2-en-1-ol

Phorbol 12-myristate 13-acetate (PMA) is a natural phorbol ester that acts as an activator of PKC, SphK, and NF-κB, and is commonly used to induce differentiation of THP-1 cells and establish dermatitis models.

L-Arginine (L-Arg) is a substrate of endothelial nitric oxide synthase (eNOS). It is transported into vascular smooth muscle cells via the cationic amino acid transporter family, where it is metabolized into nitric oxide (NO), polyamines, or L-proline. L-Arginine is an effective vasodilator and is commonly used to induce experimental acute pancreatitis.

Bicuculline is an alkaloid extracted from Corydalis decumbens, acting as a competitive antagonist of the neurotransmitter GABAA receptor (IC50 = 2 μM). It also blocks Ca2+-activated potassium (SK) channels and inhibits slow afterhyperpolarization (slow AHP). Bicuculline has anticonvulsant effects and is commonly used to establish mouse seizure models.

Colchicine is an orally active natural alkaloid that acts by inhibiting microtubule polymerization (IC50 = 3 nM) and as a competitive antagonist of the α3 glycine receptor. It possesses broad anti-inflammatory, immunosuppressive, and antifibrotic activities, can inhibit NLRP3 inflammasome activation to prevent NSAID-induced small intestine injury, holds potential for gouty arthritis and rheumatoid arthritis research, and is commonly used to establish Alzheimer’s disease models.

Amiodarone is an antiarrhythmic compound that inhibits ATP-sensitive potassium channels (IC₅₀ = 19.1 μM) and can induce pulmonary toxicity. It has shown some antiviral activity in diseases caused by SARS-CoV-2 and is commonly used to establish animal models of pulmonary fibrosis.

Scopolamine is a high-affinity (nanomolar level) muscarinic receptor antagonist that can reversibly inhibit 5-HT₃ receptor responses (IC₅₀ = 2.09 μM). It is commonly used to induce animal models of Alzheimer's disease or memory impairment.

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.

Angiotensin II human TFA is a potent vasoconstrictor in the renin-angiotensin system that regulates blood pressure through interactions with AT1R and AT2R receptors. It activates sympathetic nerve activity, promotes aldosterone synthesis and renal function, induces proliferation of vascular smooth muscle cells, and enhances type I and III collagen production in fibroblasts, leading to vascular and myocardial thickening and fibrosis. It also triggers apoptosis and promotes capillary formation, making it suitable for establishing models of cardiac hypertrophy, hypertension, and abdominal aortic aneurysm.

Doxycycline calcium is an orally active tetracycline antibiotic that also functions as a broad-spectrum matrix metalloproteinase (MMP) inhibitor, exhibiting antibacterial and anti-tumor cell proliferation activities, and is commonly used to induce gene expression in ON-OFF systems.
