glycine

(RS)-(Tetrazol-5-yl)glycine is a potent and selective N-methyl-D-aspartate (NMDA) receptor agonist that can induce seizure models and Fos expression in mice. Its EC50 values for GluN1/GluN2D and GluN1/GluN2A are 99 nM and 1.7 μM, respectively.

Urethane (Ethyl carbamate; Ethylurethane) is a byproduct formed during the fermentation process of various foods. As an ethyl ester of carbamic acid, it has the ability to inhibit the growth of bacteria, sea urchin eggs, protozoa, and plant tissues, and is commonly used for establishing lung cancer 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.

Lithocholic acid (3α-Hydroxy-5β-cholanic acid) is a toxic secondary bile acid, They were FXR antagonists (IC50=0.7, 1.4 μM), EphA2 antagonists (IC50=48, 66 μM) and EphB4 antagonists (IC50=141 μM). Lithocholic acid can promote intrahepatic cholestasis and promote tumorigenesis. Lithocholic acid is a cleanser that dissolves fat for absorption and is itself absorbed.

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.
