2-Octyl-4H-1,3,2-benzodioxaphosphorin 2-oxide (octyl-BDPO) was labelled with tritium in the 7,8-octyl and 6-BDPO positions at specific activities of 38 and 16 Ci/mmol, respectively, by catalytic reductions of the corresponding olefin and bromo precursors with tritium gas. This potent mechanism-based inhibitor for neuropathy target esterase (NTE) (I50 = 0.25 nM) and delayed neurotoxicant (active in
2-Octyl-4H-1,3,2-benzodioxaphosphorin 2-oxide (octyl-BDPO) 在 7,8-octyl 和 6-BDPO 位置用氚标记,比活分别为 38 和 16 Ci/mmol,通过用氚气催化还原相应的烯烃和溴前体。这种针对神经病变靶向酯酶 (NTE) (I50 = 0.25 nM) 和延迟神经毒剂(在母鸡中的活性为 3 mg/kg)的基于机制的有效抑制剂旨在确定保留辛基标记的磷酸化 NTE 并区分老化有无分子内NTE 活性位点处的基团转移(“烷基化”)反应来自芳基标记的命运。
