  Characterization of O,O-diethylphosphoryl oximes as inhibitors of cholinesterases and substrates of phosphotriesterases

  摘要：

  Reactivators of organophosphate (OP)-inhibited cholinesterases (ChEs) are believed to give rise to phosphorylated oximes (POX) that reinhibit the enzyme. Diethylphosphoryl oximes (DEP-OX) that were generated In situ were demonstrated in the past to be unstable, yet were more potent inhibitors of acetylcholinesterase (AChE) than the parent OPs. In view of the inconsistencies among reported results, and the potential toxicity of POXs, it seemed important to characterize authentic DEP-OXs, and to evaluate their interference with reactivation of diethylphosphoryl-ChE (DEP-ChE) conjugates. To this end, the diethylphosphoric acid esters of 1-methyl-2-pyridinium carboxaldehyde oxime (DEP-2PAM) and 1-methyl-4 pyridinium carboxaldehyde oxime (DEP-4PAM) were synthesized and chemically defined. The half-lives of DEP-2PAM and DEP-4PAM in 10 mM Tris buffer, pH 7.8, at 29 degrees were found to be 10 and 980 sec, respectively. The two DEP-OXs inhibited ChEs with the following ranking order: for DEP-2PAM, human butyrylcholinesterase (HuBChE, k(i) = 2.03 x 10(9) M-1 min(-1)) > mouse AChE (MoAChE) congruent to fetal bovine serum AChE (FBS-AChE) congruent to equine BChE (EqBChE); for DEP-4PAM, WuBChE (k(i) = 0.71 x 10(9) M-1 min(-1)) > EqBChE > MoAChE > FBS-AChE. A dialkylarylphosphate hydrolase (phosphotriesterase; PTE) from Pseudomonas sp. catalyzed the hydrolysis of DEP-4PAM with k(cat)/K-m = 3.56 x 10(7) M-1 min(-1) and K-m = 0.78 mM. Reactivation of DEP-ChEs was enhanced by PTE when di-PAM-based oximes were used as reactivators, whereas reactivation with 2-PAM-based oximes was not affected by PTE. This observation is attributed primarily to the short half-life of DEP-OXs derived from the latter oximes. Relatively low doses of PTE can detoxify large quantities of DEP-OXs rapidly, and thereby augment the efficacy of antidotes that contain the oxime function in position 4 of the pyridine ring.

  TGR5激动剂3,4,5-三取代的4,5-二氢-1,2,4-恶二唑的设计，合成与结构-活性关系

  摘要：

  鉴于其在能量和葡萄糖稳态中的介导作用，G蛋白偶联胆汁酸受体1（TGR5）被认为是治疗2型糖尿病和其他代谢性疾病的潜在靶标。通过对已发表的TGR5激动剂的各种结构进行全面分析，建立了一个假设的基于配体的药效团模型，并基于新型3,4,5-三取代的4,5-二氢-1，2来开发了一类新型的强效TGR5激动剂。 ，4-恶二唑核是通过合理设计发现的。本文报道了三种不同的合成方法来构建4,5-二氢-1,2,4-恶二唑和广泛的结构-活性关系研究。化合物（R）-54 n，其结构是通过单晶X-射线衍射和量子化学固态TDDFT-ECD计算确定，显示出最好的效力，用EC 50为1.4的n值中号朝向hTGR5。它在体外的有利特性值得进一步研究。
