based on approved drugs, were initially screened. They were then tested in various binary solutions, for their detoxification efficacy and degradation ability towards lipophilic OP CWA models such as dibutylphosphofluoridate and o-nitro-phenyl diphenyl phosphate, as well as the nerve agent VX, by means of kinetic 31P NMR and UV–Vis spectroscopy. Of these, the potassium and diethyl ammonium salts of acetohydroxamic
皮肤暴露于低挥发性有机
磷化学战剂(OP CWA)对暴露者造成巨大风险。由于它们的亲脂性质,这些化合物迅速吸收到皮肤中,导致形成“皮肤贮库”,它们从中缓慢进入血液,导致长期中毒。传统上,应对此类物质毒性的策略包括
化学去污/从皮肤表面物理清除残留剂(最好在暴露后尽快清除)和在出现中毒迹象时施用解毒剂。因此,这些策略不能抵消大量的试剂,这些试剂积聚在皮肤贮库中。十多年前,有人提出了一种旨在中和真皮储层的“追赶疗法”的概念。在此,我们描述了潜在的“追赶疗法”乳液示例-旨在将小的亲核分子传递到皮肤中并可能在残留的CWA到达血流之前分解的媒介物。最初筛选了基于已批准药物的11种亲核化合物。然后在各种二元溶液中测试它们的解毒功效和对亲脂性OP CWA模型的降解能力,例如
