(-)-p-Bromotetramisole Oxalate(L-(-)-p-Bromotetramisole Oxalate\L-p-Bromotetramisole Oxalate\(-)-4-Bromotetramisole Oxalate)是一种有效的非特异性碱性磷酸酶抑制剂,也是一种蛋白酪氨酸磷酸酶抑制剂[1][2].
碱性磷酸酶是一种水解酶,可将磷酸基团从核苷酸\蛋白和生物碱上移除.蛋白酪氨酸磷酸酶是将磷酸基团从靶蛋白的磷酸化酪氨酸残基上移除的酶.
(-)-p-Bromotetramisole Oxalate是碱性磷酸酶和蛋白酪氨酸磷酸酶的抑制剂.在各种大鼠组织中,(-)-p-Bromotetramisole Oxalate(0.1 μM)可完全抑制非特异性的碱性磷酸酶[1].在大鼠球状带中,(-)-p-Bromotetramisole Oxalate(100 μM)可阻断血管紧张素II诱导的Na+泵(Na+, K+-ATPase)抑制.这一结果表明血管紧张素II诱导的Na+泵抑制可能是由酪氨酸磷酸酶介导[2].在神经分泌PC12细胞中,(-)-p-Bromotetramisole Oxalate(0.3 mM)可提高离子霉素刺激的去甲肾上腺素(NA)释放,表明酪氨酸磷酸化调控Ca2+刺激的NA释放[3].
在Sprague-Dawley大鼠中,(-)-p-Bromotetramisole Oxalate(10 μM)可将磷酸盐排泄分数(FEPi)从4.7%显著提高到13.4%[4].
