HY-145538

2'-Deoxyguanosine 5'-monophosphate disodium hydrate 5'-Deoxyguanylic acid disodium hydrate	DNA/RNA Synthesis	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) .

HY-W002004

4-Amino-tempo 4-Amino-2,2,6,6-tetramethylpiperidine-1-oxyl	Biochemical Assay Reagents	Others
4-Amino-TEMPO can be used as a spin label for detecting radicals and the damage caused by them. 4-Amino-TEMPO possesses superoxide dismutase-mimetic activity, enabling it to easily penetrate cells and protect them from oxidative damage induced by H₂O₂. Additionally, 4-Amino-TEMPO exhibits significant radiation protective properties, effectively safeguarding DNA from oxidative stress-induced damage caused by UV exposure due to its ability to maintain a positive charge. Furthermore, 4-Amino-TEMPO is a highly selective oxidation catalyst widely used in the research and development of various specialty chemicals, including fragrances, pesticides, and others .

HY-112356

Scytonemin	Apoptosis Reactive Oxygen Species Polo-like Kinase (PLK)	Inflammation/Immunology Cancer
Scytonemin is a hydrophobic alkaloid pigment that can be isolated from the outer sheath of cyanobacteria. Scytonemin has protective function against short-wave solar ultraviolet (UV) radiation, which can reduce the generation of reactive oxygen species (ROS) and the formation of DNA damage. Scytonemin also has anti-inflammatory and anti-proliferative activities, produces concentration-dependent inhibition (IC₅₀=2.0 μM) of polo-like kinase 1 (PLK1)-mediated cdc25C phosphorylation, and plays an important role in regulating the G2/M transition in the cell cycle. It can be used in the research of cancer, acute inflammation and sunscreen cosmetics .
