  Cyclohexylcarbamic Acid 3‘- or 4‘-Substituted Biphenyl-3-yl Esters as Fatty Acid Amide Hydrolase Inhibitors:  Synthesis, Quantitative Structure−Activity Relationships, and Molecular Modeling Studies

  摘要：

  Fatty acid amide hydrolase (FAAH) is a promising target for modulating endocannabinoid and fatty acid ethanolamide signaling, which may have important therapeutic potential. We recently described a new class of O-arylcarbamate inhibitors of FAAH, including the cyclohexylcarbamic acid biphenyl-3-yl ester URB524 (half-maximal inhibitory concentration, IC50 = 63 nM), which have significant anxiolytic-like properties in rats. In the present study, by introducing a selected group of substituents at the meta and para positions of the distal phenyl ring of URB524, we have characterized structure-activity profiles for this series of compounds and shown that introduction of small polar groups in the meta position greatly improves inhibitory potency. Most potent in the series was the m-carbamoyl derivative URB597 (4i, IC50 = 4.6 nM). Furthermore, quantitative structure-activity relationship (QSAR) analysis of an extended set of meta-substituted derivatives revealed a negative correlation between potency and lipophilicity and suggested that small-sized substituents may undertake polar interactions with the binding pocket of the enzyme. Docking studies and molecular dynamics simulations, using the crystal structure of FAAH, indicated that the O-biphenyl scaffold of the carbamate inhibitors can be accommodated within a lipophilic region of the substrate-binding site, where their folded shape mimics the initial 10-12 carbon atoms of the arachidonyl moiety of anandamide (a natural FAAH substrate) and methyl arachidonyl fluorophosphonate (a nonselective FAAH inhibitor). Moreover, substituents at the meta position of the distal. phenyl ring can form hydrogen bonds with atoms located on the polar section of a narrow channel pointing toward the membrane-associated side of the enzyme. The structure-activity characterization reported here should help optimize the pharmacodynamic and pharmacokinetic properties of this class of compounds.

  摘要：

  C-CN键的选择性氢解可让化学家利用氰基的邻位导向能力，α-CH酸度和吸电子能力进行合成操作。我们已经发现，通过使用镍催化剂，仅在1 bar的氢气下就可以芳基和脂肪族氰化物进行氢解。该方案适用于芳基氰化物指导的官能化反应和苄基氰化物的α-取代。

  日期：2003.8

  Aryl nitriles have been found to participate in cross-coupling and amination reactions via nickel-catalyzed activation of the C-CN bond. With the development of these synthetically useful transformations, aryl nitriles can now be considered along with aryl halides and sulfonates as viable substrates for these types of reactions.

  Palladium nanoparticle (Pd NP) catalysts immobilized in a polymer with an N-heterocyclic carbene (NHC) moiety (PICB-NHC-Pd) have been developed, wherein the NHC moiety plays dual roles as a crosslinker and a ligand to activate the Pd NPs. The presence of both Pd NPs and NHC was confirmed by STEM/EDS and SR-MAS NMR analyses, respectively. This PICB-NHC-Pd catalyst showed excellent activity in the Suzuki–Miyaura

  Inert aryl methyl ethers as coupling components via C–O activation have been established with a Ni catalyst for C–H activation of heteroarene. The key to simultaneous C–H/C–O bond activation is the use of sterically demanding o-tolylMgBr. The protocol is effective for a wide scope of substrates including naphthyl methyl ethers, anisoles, and a variety of other heteroarene derivatives. Detailed mechanistic

  惰性芳基甲基醚作为通过C–O活化的偶联组分，已经建立了Ni催化剂用于杂芳烃的C–H活化。同时的C-H / C-O键活化的关键是使用的空间要求的邻tolylMgBr。该协议可用于多种底物，包括萘基甲基醚，茴香醚和各种其他杂芳烃衍生物。详细的机理研究表明，在此C–H / C–O反应中，镍和格氏试剂的协同作用有助于C–O裂解，这得到DFT计算的支持。在这个阶段，单电子转移可以被排除为该串联策略的主要操作过程。
