Purity:  99.82%
1,7-Dimethyluric acid is an N-methylated uric acid and purine derivative, as well as a caffeine metabolite. When 1,7-Dimethyluric acid is acted upon by peroxidase in the presence of H2O2, it follows the same oxidation pathway to generate a UV-absorbing intermediate, which decays via first-order kinetics. 1,7-Dimethyluric acid can adsorb onto pyrolytic graphite electrodes, but not onto glassy carbon electrodes or platinum electrodes. The N-methylation modification of its pyrimidine ring prevents ring contraction of the diol intermediate, and no NMR evidence of O-alkylation is observed during propylation under the test conditions [2] .

Target:  

DNA/RNA Synthesis

Research Areas:  

Others

2'-Deoxyguanosine 5'-monophosphate (5'-Deoxyguanylic acid; dGMP) disodium hydrate is an oxidizable target of the photosensitizer pterin (PT) and can be used to evaluate the photosensitizing properties of biopterins (such as Bip, Fop and Cap) . Pterin causes a photosensitive reaction of dGMP under UV-A radiation, causing damage to DNA molecules. There are two main mechanisms for the photosensitive oxidation of purine nucleotides by pterin in vitro: one is the hydrogen abstraction reaction of electron transfer from dGMP to the triplet excited state of pterin (type I mechanism), and the other is the interaction between dGMP and pterin. The reaction produces singlet molecular oxygen (1O2) (Type II mechanism) [2].
