4-Aminohippuric acid Chemical Properties,Usage,Production

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

p-Aminohippuric acid has been used as infusions to measure plasma flow.

Uses

4-Aminohippuric Acid is used in the measurement of renal plasma flow as a diagnostic tool which may be applied towards kidney disorders.

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.]
