Beschreibung

General description

A ubiquitous coenzyme that acts as an electron donor in many reactions utilizing dehydrogenase and reductase enzymes. It is generated by reduction of the electron acceptor NADP⁺. The following biological pathways involve NADPH: formation of carbohydrate from CO₂ during photosynthesis, maintenance of high levels of reduced glutathione in erythrocytes, reduction of thioredoxin.

Application

NADPH, tetrasodium salt, has been used:

• as a cofactor in the enzymatic synthesis of epoxidized metabolites from polyunsaturated fatty acids, facilitating the epoxidation reaction catalyzed by the cytochrome P450 enzyme BM3[1]
• in microsomal assays to evaluate the metabolic stability of CHD1L inhibitors[2]
• in conjunction with glutathione to reduce S-glutathionylated cysteine groups during the biotin switch assay, facilitating the detection of protein S-glutathionylation in the study of HLTF-deleted colorectal cancer models

Preparation Note

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 2 months at -20°C.
