Beschreibung

General description

2-Thiouracil is a thio-derivative of uracil, a pyrimidine nucleobase.This antithyroid drug has less solubility in H₂O & organic solvents.

Application

2-Thiouracil may be used:

• in the synthesis and characterization of silver colloid and film substrates and their applications in surface-enhanced Raman scattering (SERS)
• to study its electro-oxidation and determination at titanium dioxide (TiO2) nanoparticles-modified gold electrode
• to study the effect of methylation on the deactivation mechanism or the triplet-state dynamics of 2-thiouracil using time-resolved photoelectron spectroscopy

Biochem/physiol Actions

2-Thiouracil acts as an anticancer, antithyroid, and antiviral agent. 2-Thiouracil is a selective melanoma-seeker and competitive inhibitor of neuronal nitric oxide synthase.[1] It also forms complexes with transition metals such as gold (Au), chromium (Cr), zinc (Zn), and silver (Ag).2-thiouracil can be incorporated into the tissue culture medium to inhibit virus replication or movement from infected to healthy tissues during chemotherapy.
