Bromotetramisole, L(-) oxalate | Alkaline phosphatase inhibitor

Bromotetramisole oxalate (62284-79-1) is a potent alkaline phosphatase inhibitor.1 Strongly activates cystic fibrosis transmembrane conductance regulator (CFTR) chloride channels by inhibiting a membrane associated protein phosphatase.2 Bromotetramisole oxalate inhibits terminal cell division-associated differentiation in murine erythroleukemia cells.3
