Beschreibung

Allgemeine Beschreibung

A membrane-permeable phosphotyrosine phosphatase inhibitor (IC₅₀ = 18 µM). Stimulates 2-deoxyglucose transport in insulin-resistant human skeletal muscle and activates P56^lck protein tyrosine kinase. Blocks TNFα-dependent activation of the NF-κB in human myeloid ML-1a cells. PAO inhibits the protease activities of recombinant human caspases, as well as endogenous chicken caspases that are active in extracts of preapoptotic chicken DU249 cells (S/M extracts). At 100 µM, it also blocks the morphological changes of nuclear apoptosis in vitro and internucleosomal DNA fragmentation in S/M extracts without interfering with PARP or lamin A cleavage. Also known to cause complete and reversible inhibition of NADPH oxidase in human neutrophils.
