Inhibitors

Inhibitors Comment Organism Structure
3-methyl-2-butenal 95% remaining activity at 0.5 mM Homo sapiens
acetaldehyde more than 95% remaining activity at 0.5 mM Homo sapiens
acrolein 4% remaining activity at 0.5 mM, potent irreversible time-dependent inhibitor, addition of 1 mM vanadate slows inactivation of PTP1B by 0.5 mM acrolein Homo sapiens
crotonaldehyde 85% remaining activity at 0.5 mM Homo sapiens
Glyoxal 93% remaining activity at 0.5 mM Homo sapiens
additional information the presence of the superoxide- and hydrogen peroxide-destroying enzymes superoxide dismutase and catalase has no effect on the rate of the inactivation reaction Homo sapiens
propanal 93% remaining activity at 0.5 mM Homo sapiens
