| | XANTHURENIC ACID Usage And Synthesis |
| Chemical Properties | ochre powder | | Uses | Excreted by pyridoxine-deficient animals after the ingestion of tryptophan. | | 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.
| | 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.] |
