| | 4-Aminohippuric acid Usage And Synthesis |
| Description | 4-Aminohippuric acid 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). 4-Aminohippuric acid is a glycine amide form of 4-aminobenzoic acid . Formulations containing 4-aminohippuric acid have been used as markers to determine renal plasma flow. | | Chemical Properties | off-white to greyish crystalline powder | | Uses | muscle relaxant (smooth) | | Uses | 4-Aminohippuric Acid is used in the measurement of renal plasma flow as a diagnostic tool which may be applied towards kidney disorders. | | Uses | p-Aminohippuric acid has been used as infusions to measure plasma flow. | | Definition | ChEBI: P-aminohippuric acid is an N-acylglycine that is the 4-amino derivative of hippuric acid; used as a diagnostic agent in the measurement of renal plasma flow. It has a role as a Daphnia magna metabolite. It is a conjugate acid of a p-aminohippurate. | | 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 | [1] B.
