  A Perturbed pK_a at the Binding Site of the Nicotinic Acetylcholine Receptor:  Implications for Nicotine Binding

  摘要：

  A series of tethered quaternary ammonium derivatives of Tyr have been incorporated into the binding site of the nicotinic acetylcholine receptor (nAChR) using the in vivo nonsense suppression method, producing constitutively active (self-gating) receptors. We have incorporated primary, secondary, and tertiary amine tethered agonists to give receptors whose constitutive activity can be modulated by pH. Lowering the pH protonates the tethered amine, giving it a positive charge and allowing it to reversibly activate the receptor. Tertiary and secondary tethered amines, TyrO3T and TyrO3S, have been successfully incorporated at alpha149 in the nAChR. Constitutive currents at pH 5.5 are 6 times those at pH 9.0. The pKa of TyrO3T in the binding site appears to be 6 or lower, differing substantially from its pKa in solution ( approximately 9.3). This local pKa perturbation has substantial implications for pharmacological research on the nAChR: of the tertiary agonists considered, noracetylcholine experiences this pKa perturbation, while nicotine does not.

  克服脱芳基化问题：芳烷基烯丙基醚，胺和氨基酸的钯（II）催化的化学，区域和立体选择性烯丙基氧化。

  摘要：

  我们在此报告了芳基烯丙基醚，胺和氨基酸的Pd（II）/双亚砜催化的分子内烯丙基CH乙酰氧基化，同时保留了不稳定的烯丙基部分。从机理上讲，反应是通过从烯丙基位置到乙烯基位置的独特的双键异构化进行的，然后进行分子内羧基palpalpalation和β-氢化物消除途径。首次建立了具有出色的非对映选择性的N-烯丙基保护氨基酸的C–H氧化，可通过1,3-syn加成提供五元杂环。
