Usage

General Description

The chemical 2,3-dihydro-6,7-dimethyl-2-thioxo-1H-pteridin-4-one, also known as allopurinol, is a medication used to treat gout and high levels of uric acid in the blood. It works by reducing the production of uric acid in the body. Allopurinol is also used to prevent kidney stones and to treat certain types of kidney disease. It is a xanthine oxidase inhibitor and is typically taken orally. Allopurinol has been on the World Health Organization's List of Essential Medicines since 2017, making it one of the most important medications needed in a basic health system. While generally well tolerated, side effects may include rash, nausea, and liver inflammation. Long-term use of allopurinol has been associated with an increased risk of adverse reactions such as hypersensitivity syndrome and liver toxicity.

Gold(I) complexes incorporating emissive mercapto-pteridine ligands: Syntheses, X-ray structure, luminescence and preliminary cytotoxic evaluation

The syntheses of six new mixed P/S-donor two-coordinate AuI complexes are described. The complexes incorporate a pteridinyl ligand coordinated through a thiolate donor, and an ancillary tertiary phosphane (PPh3 or PCy3). The mercapto-pteridine ligands (L 1-L3) differ in the nature of the substituents on the pteridine core. An X-ray crystal structure was obtained for one of the examples, [(L1)Au(PPh3)], revealing weak intermolecular interactions between two molecules of the complex: π-π contacts between aromatic rings appear to support an intermolecular Au-Au contact of approximately 3.05 A. All of the complexes are luminescent in solution, with emission arising from tuneable ligand-based excited states, and characterised as a perturbed fluorescence in nature. In this context, complexes of L3 displayed useful visible absorption and emission. Preliminary cytotoxicity assessments were conducted using the MTT assay, and the complexes each displayed impressive anti-proliferative activities (IC50 a given pteridine moiety, triphenylphosphane appeared to be the co-ligand of choice for enhancing biological activity.
