| Hazard Information | Back Directory | [Description]
4-Aminohippuric acid (61-78-9) is a substrate for various renal transporters that has been used in the study of anion uptake in the kidney. It is a substrate for organic anion transporter 1 (OAT1; Km = 14.3 μM in X. laevis oocytes), the human inorganic phosphate transporter (NPT1; Km = 2.66 mM in HEK293 cells), and apical multidrug resistance protein (MDR2; Km = 880 μM in HEK293 cells).1,2,3 4-Aminohippuric acid is a glycine amide form of 4-aminobenzoic acid (Item No. 18659). Formulations containing 4-aminohippuric acid have been used as markers to determine renal plasma flow.

ChEBI: An N-acylglycine that is the 4-amino derivative of hippuric acid; used as a diagnostic agent in the measurement of renal plasma flow. | [General Description]
Renal tubules secretes para amino hippuric acid/PAH. | [Biochem/physiol Actions]
Para-aminohippuric acid?(PAH) is used as a marker in nutrition studies to measure the flow of blood in pigs, which inturn helps to determine the portal-drained viscera (PDV) flux of nutrients. | [Synthesis]
4-Aminohippuric acid is prepared by reacting p-nitrobenzoyl chloride with glycine, followed by reducing the p-nitro group with tin and hydrochloric acid. | [Purification Methods]
Crystallise the acid from H2O. It is soluble in organic solvents. [Cohen & McGilvery J Biol Chem 169 119 1945, 171 121 1947, Meunzen et al. J Biol Chem 26 469 1926, Beilstein 14 III 1069, 14 IV 1152.] | [References]
