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] .

PSDalpha is a photoactivatable PS-Degron targeting estrogen receptor α (ERα/ESR1), with a Ki of 72.8 nM for ERα. PSDalpha consists of an ERα-targeting estradiol moiety conjugated via an alkyne bond to triphenylamine-benzothiadiazole (TB), an aggregation-induced emission (AIE) photosensitizer. Upon visible light irradiation, PSDalpha generates singlet oxygen ( 1O2) and induces controllable ERα degradation. PSDalpha also induces G1 phase arrest and apoptosis. PSDalpha can be used in studies related to ERα-positive breast cancer and light-controlled targeted protein degradation .

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].

Veratryl alcohol- 13C (3,4-Dimethoxybenzyl alcohol- 13C) is the 13C-labeled Veratryl alcohol (HY-107858). Veratryl alcohol (3,4-Dimethoxybenzyl alcohol) is a secondary metabolite of lignin-degrading fungi, commonly used as a substrate for lignin peroxidase (LiP) to measure lignin degradation activity. Veratryl alcohol protects LiP from inactivation by H2O2 and prevents the accumulation of LiP III compounds. Veratryl alcohol also acts as a stabilizer for manganese-dependent peroxidases (MnP). Veratryl alcohol is a quorum-sensing inhibitor (QSI) and exhibits antibacterial efficacy [2] .
