The efficacy of presently used therapeutic oximes (such as pralidoxime, obidoxime, HI-6, etc.) as reactivators of inhibited AChE is different for various organophosphate. Moreover, the used oximes are hard to resolve in human blood and can t penetrate center nerve system easily. So many researchers work hard to seek for a broad-spectrum oxime suitable for the antidotal agents of poisoning with all organophosphorus.

由于当前所用的解磷啶、双复磷、HI-6等肟类解毒药对各种有机磷毒剂的重活化效果差异较大，脂溶性差，难以通过生物膜渗透到中枢神经系统，对中枢激动症状无显著疗效，因而寻求高效能的重活化剂一直是许多研究者努力的方向。
