Background:

(-)-p-Bromotetramisole Oxalate (L-(-)-p-Bromotetramisole Oxalate, L-p-Bromotetramisole Oxalate, (-)-4-Bromotetramisole Oxalate) is a potent and non-specific inhibitor of alkaline phosphatase and is also an inhibitor of protein tyrosine phosphatases [1] [2].


Alkaline phosphatase is a hydrolase enzyme that removes phosphate groups from nucleotides, proteins and alkaloids. Protein tyrosine phosphatase is an enzyme that removes phosphate groups from phosphorylated tyrosine residues on target proteins.


(-)-p-Bromotetramisole Oxalate is an inhibitor of alkaline phosphatase and protein tyrosine phosphatases. In various rat tissues, (-)-p-Bromotetramisole Oxalate (0.1 μM) completely inhibited non-specific alkaline phosphatase [1]. In rat zona glomerulosa, (-)-p-Bromotetramisole Oxalate (100 μM) blocked the inhibition of Na+ pump (Na+, K+-ATPase) induced by angiotensin II. The result suggested that inhibition of the Na+ pump induced by angiotensin II might be mediated by a tyrosine phosphatase [2]. In neurosecretory PC12 cells, (-)-p-Bromotetramisole Oxalate (0.3 mM) increased ionomycin-stimulated noradrenaline (NA) release, which suggested that tyrosine phosphorylation regulated Ca2+-stimulated NA release [3].


In Sprague-Dawley rats, (-)-p-Bromotetramisole Oxalate (10 μM) significantly increased fractional excretion of phosphate (FEPi) from 4.7% to 13.4% [4].
