Allgemeine Beschreibung

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

Anwendung

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. Wirkung

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. 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.

2-thiouracil (TU), an established antithyroid drug and melanoma-seeker, was found to selectively inhibit neuronal nitric oxide synthase (nNOS) in a competitive manner (K(i)=20 microM), being inactive on the other NOS isoforms. The drug apparently interfered with the substrate- and tetrahydrobiopterin

4-Pyrimidinone ribofuranoside (H(2)o(4)U) and 4-pyrimidinone 2'-deoxyribofuranoside (dH(2)o(4)U) were synthesized by the oxidative desulfurization of parent 2-thiouracil nucleosides with m-chloroperbenzoic acid. The crystal structures of H(2)o(4)U and dH(2)o(4)U and their conformations in solution were determined and compared with corresponding 2-thiouracil and
