4-Hydroxyquinazoline, 98%
Description
4-Hydroxyquinazoline is been used to inhibit PARP (poly(ADP-ribose) synthetase) which catalyzes covalent attachment of the ADP-ribose moiety of NAD+ to various proteins. This compound specifically and potently inhibits PARP-1. 4-HQN demonstrates the ability to decrease activation of transcription factor NFκB and AP-1 in lipopolysaccharide-induced shock. Mechanistic studies indicate that 4-HQN activates PI3-kinase/Akt pathway in the liver, spleen, and lung and down-regulates two elements of the MAP kinase system. Additionally, this agent has been observed to decrease ischemia-reperfusion-induced increase of protein oxidation, single-strand DNA breaks, lipid peroxidation, and mitochondrial reactive oxygen species production in the reperfusion period.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
