Lp-溴四咪唑草酸酯是一种非特异性碱性磷酸酶的抑制剂，其活性可与钒化合物原钒酸酯媲美。Lp-溴四咪唑草酸酯未显示出对特定磷酸酶活性的抑制作用，而D-对映异构体未显示出对任一磷酸酶的抑制作用。据报道，酪氨酸磷酸酯酶的活性也被草酸L-溴四咪唑和相关化合物抑制。Lp-溴四咪唑草酸酯，（-）-p-溴四咪唑草酸酯，L-对-溴四咪唑和（6S）-6-（4-溴苯基）-2,3,5,6-四氢呋喃-咪唑并[2,1-b]噻唑单乙二酸酯。 L-p-Bromotetramisole oxalate is an inhibitor of non-specific alkaline phosphatase, comparable in activity to the vanadium compound Orthovanadate . L-p-Bromotetramisole oxalate shows no inhibition of specific phosphatase activity, and the D- enantiomer shows no inhibitory effects against either phosphatase. The activity of tyrosine phosphatases is also reported to be inhibited by L-p-Bromotetramisole oxalate and related compounds. L-p-Bromotetramisole oxalate is also known as 6-Bromolevamisole oxalate, (?)-p-Bromotetramisole oxalate, L-para-Bromotetramisole, and (6S)-6-(4-bromophenyl)-2,3,5,6-tetrahydro-imidazo[2,1-b]thiazole, monoethanedioate.
