  Development of Molecular Probes for the Identification of Extra Interaction Sites in the Mid-Gorge and Peripheral Sites of Butyrylcholinesterase (BuChE). Rational Design of Novel, Selective, and Highly Potent BuChE Inhibitors

  摘要：

  Tacrine heterobivalent ligands were designed as novel and reversible inhibitors of cholinesterases. On the basis of the investigation of the active site gorge topology of butyrylcholinesterase (BuChE) and acetylcholinesterase (AChE) and by using flexible docking procedures, molecular modeling studies formulated the hypothesis of extra interaction sites in the active gorge of hBuChE, namely, a mid-gorge interaction site and a peripheral interaction site. The design strategy led to novel BuChE inhibitors, balancing potency and selectivity. Among the compounds identified, the heterobivalent ligand 4m, containing an amide nitrogen and a sulfur atom at the 8-membered tether level, is one of the most potent and selective BuChE inhibitors described to date. The novel inhibitors, bearing postulated key features, validated the hypothesis of the presence of extra interaction sites within the hBuChE active site gorge.

  Herein we report a complete family of conformationally restricted PProDOT derivatives with varying alkylene tether lengths. It was found that variation of the tether length and structure of the electropolymerizable monomer was successful in the fine-tuning of the electrochemical and optical properties of the subsequent material. It was found that the band gap of the materials could be varied between 1.94 and 2.26 eV, with the “sweet spot” for obtaining the maximum electronic band gap existing at the n = 6 tether length, while maintaining low redox potentials. It was also found that these polymers exhibited stable electrochromic behavior with colors varying from blue–purple to orange in their neutral states and transmissive in their doped states.

  本文报道了一组构象受限的PProDOT衍生物家族，其烷撑链长度各异。研究发现，通过改变链长及电聚合单体的结构，能够成功微调后续材料的电化学和光学性质。材料的带隙可在1.94至2.26电子伏特之间变化，其中最佳链长n=6时可获得最大电子带隙，同时保持较低的氧化还原电位。这些聚合物还表现出稳定的电致变色行为，它们在中性状态下的颜色从蓝紫色到橙色不等，而在掺杂状态下则呈透明态。

  An efficient and economical synthesis of a series of rationally designed novel 9,9′-(alkane-1,ω-diyldiimino)-1,2,3,4-tetrahydroacridines (ω = 7–10) and a second series of new analogues, 9-(ω-phenylalkylamino)-1,2,3,4-tetrahydroacridines (ω = 4–10), is reported. Compounds in the first series are found to be up to 10 000-fold more selective and 1000-fold more potent in reversibly inhibiting rat acetylcholinesterase (AChE) than the monomer, 9-amino-1,2,3,4-tetrahydroacridine (THA). Some members in the latter series (ω = 7–8) are slightly more potent than THA in inhibiting AChE but still more selective. These compounds can serve as (i) important chemical tools to evaluate the role of AChE inhibition by THA, a clinical drug, in treating Alzheimer’s disease, (ii) effective, safer and low-cost insecticides and parasiticides, (iii) potential blockers of the K+ channel and the N-methyl-D-aspartate receptor channel, and perhaps (iv) improved therapeutics for Alzheimer’s disease.

• Fingerprinting a transition-structure guest by a building-block approach with an incremental series of catalytic hosts. Structural requirements for glyme and .alpha.,.omega.-dimethoxyalkane catalyses in N-methylbutylaminolysis and butylaminolysis of 4-nitrophenyl acetate in chlorobenzene
  作者：John C. Hogan、Richard D. Gandour

  日期：1992.1

  Glymes, H-(CH2OCH2)n-H, GLM(n), catalyze butylaminolysis of 4-nitrophenyl acetate in chlorobenzene. Values of k(cat)/Oxy, where Oxy is the number of oxygens in the catalyst, increase with oligomer length up to triglyme, GLM(4), and then plateau. Optimal catalysis on a per oxygen basis requires a -(CH2OCH2)4-fragment, which suggests a four-point recognition of the secondary ammonium ion of the zwitterionic tetrahedral intermediate (TI) (J. Org. Chem. 1991, 56, 2821-2826). Dissection of individual structural components and reassembly to the same structure of the complex verifies this model. The following kinetic studies of 4-nitrophenyl acetate in chlorobenzene have accomplished the task: (a) methylbutylaminolysis catalyzed by GLM(n), n = 2-4; (b) methylbutylaminolysis catalyzed by alpha,omega-dimethoxyalkanes, CH3O-(CH2)n-OCH3, DME(n), n = 2-10 and 12; and (c) butylaminolysis catalyzed by DME(n), n = 2-10 and 12. Experiment a has revealed that k(cat)/Oxy is the same for GLM(2)-GLM(4). Optimal catalysis for breakdown of a zwitterionic TI with one ammonium proton only requires a -(CH2OCH2)2- fragment. Experiment b has shown that k(cat)/Oxy is largest for DME(2) with the values for the remaining DMEs 2-2.5-fold lower. A -CH2CH2- is the best spacer between the two oxygens. Thus, bifurcated hydrogen-bond formation between the two oxygens and the one ammonium proton enhances catalysis. Experiment c has revealed that k(cat)/Oxy for DME(2) exceeds the remaining DMEs by 3-3.6-fold, except for DME(8) and DME(10), which have values of k(cat)/Oxy only 1.7-fold slower. DME(8), the carba analogue of GLM(4), likely binds to the two ammonium protons individually with the two oxygens. DME(10) behaves similarly. GLM(4) catalysis of butylaminolysis identifies -(CH2OCH2)4- as an optimal size. DME(8) catalysis confirms this size, although the two catalysts stabilize the two-proton ammonium ion differently. GLM(4) catalyzes butylaminolysis by forming two bifurcated hydrogen bonds. This suggested structure defines the size of the ammonium ion, which agrees with X-ray structural studies of polyether-ammonium complexes. Mechanistic proposals of butylaminolysis of aryl esters require such an ion. The results of this study confirm the structure of the ion in the rate-limiting step. This building-block approach is a method for ''fingerprinting'' ammonium ions in transition structures of ionogenic reactions.
