XANTHURENIC ACID Usage And Synthesis

Chemical Properties

ochre powder

Uses

caspase activator, guanylyl cyclase stimulant

Uses

Xanthurenic acid can be used as a substrate for the synthesis of:

• Silica-gel functionalized xanthurenic acid (4, 8-dihydroxyquinoline-2-carboxylic acid) as an adsorbent for metal ions.
• N, N′-bis-((8-hydroxy-7-quinolinyl)methyl)-1,10-diaza-18-crown-6 ethers as fluorescent sensors of magnesium in living cells via one-pot Mannich reaction.
• Poly-xanthurenic acid (poly-Xa) for biosensing applications.

Uses

Excreted by pyridoxine-deficient animals after the ingestion of tryptophan.

Definition

ChEBI: A quinolinemonocarboxylic acid that is quinoline-2-carboxylic acid substituted by hydroxy groups at C-4 and C-8.

storage

Room temperature

Purification Methods

It is precipitated by the addition of 2N formic acid to its solution in hot 2M ammonia (charcoal). The solid is filtered off, dried in a vacuum at ~80o in the dark. UV (H2O) has nm ( M-1cm-1): 243 (30,000) and 342 (6,500). The methyl ester has m 262o (from MeOH). It forms Cu2+, Zn2+, Fe2+ and Fe3+ salts. [Beilstein 22 III/IV 2513.]
