  Synthesis and anti-acetylcholinesterase properties of novel β- and γ-substituted alkoxy organophosphonates

  摘要：

  Activated organophosphate (OP) insecticides and chemical agents inhibit acetylcholinesterase (AChE) to form OP-AChE adducts. Whereas the structure of the OP correlates with the rate of inhibition, the structure of the OP-AChE adduct influences the rate at which post-inhibitory reactivation or aging phenomena occurs. In this report, we prepared a panel of beta-substituted ethoxy and gamma-substituted propoxy phosphonoesters of the type p-NO2PhO-P(X)(R)[(O(CH2)(n)Z] (R = Me, Et; X = O, S; n = 2, 3; Z = halogen, OTs) and examined the inhibition of three AChEs by select structures in the panel. The beta-fluoroethoxy methylphosphonate analog (R = Me, Z = F, n = 2) was the most potent anti-AChE compound comparable (k(i); similar to 6 x 10(6) M-1 min(-1)) to paraoxon against EEAChE. Analogs with Z = Br, I, or OTs were weak inhibitors of the AChEs, and methyl phosphonates (R = Me) were more potent than the corresponding ethyl phosphonates (R = Et). As expected, analogs with a thionate linkage (P=S) were poor inhibitors of the AChEs. (C) 2013 Elsevier Ltd. All rights reserved.

  The invention provides compounds that inhibit cholinesterases, such as acetylcholinesterase and butyrylcholinesterase. Such compounds are useful to prevent or treat exposure of a patient (e.g., a human) to an organophosphoric nerve agent (e.g., sarin and VX) or to treat a patient suffering from a neurodegenerative disorder such as Alzheimer's Disease or Lewy Body Dementia. The compounds are further useful as diagnostic tools for use in medical or research radiography (e.g., positron emission tomography) when synthesized with a radionuclide (e.g., [18F]. Synthetic schemes to produce such compounds are also provided.

  本发明提供了抑制胆碱酯酶（如乙酰胆碱酯酶和丁酰胆碱酯酶）的化合物。这种化合物可用于预防或治疗患者（例如人类）暴露于有机磷神经毒剂（例如沙林和VX）的情况，或治疗患有神经退行性疾病（例如阿尔茨海默病或Lewy体痴呆症）的患者。这些化合物还可用作医学或研究放射学（例如正电子发射断层扫描）中的诊断工具，当与放射性核素（例如[18F]）合成时。本发明还提供了合成这些化合物的合成方案。
