  4-(Tetrazolylalkyl)piperidine-2-carboxylic acids. Potent and selective N-methyl-D-aspartic acid receptor antagonists with a short duration of action

  摘要：

  We have prepared a series of cis-4-(tetrazolylalkyl)piperidine-2-carboxylic acids as potent and selective N-methyl-D-aspartic acid (NMDA) receptor antagonists. NMDA antagonists may prove to be useful therapeutic agents, for instance, as anticonvulsants, in the treatment of neurodegenerative disorders such as Alzheimer's disease and in the prevention of neuronal damage that occurs during cerebral ischemia. The compounds prepared were evaluated in vitro in both receptor binding assays ([H-3]CGS-19755, [H-3]AMPA, and [H-3]kainic acid) and in a cortical-wedge preparation (versus NMDA, quisqualic acid, and kainic acid) to determine affinity, potency, and selectivity. The new amino acids were also evaluated in vivo for their ability to block NMDA-induced convulsions in neonatal rats and NMDA-induced lethality in mice. The most potent compound of this series, 15 (LY233053), selectively displaced [H-3]CGS-19755 binding with an IC50 of 107 +/- 7 nM and selectively antagonized responses due to NMDA in a cortical-wedge preparation with an IC50 of 4.2 +/- 0.4-mu-M. Compound 15 blocked both NMDA-induced convulsions in neonatal rats (minimum effective dose (MED) = 20 mg/kg ip) and NMDA-induced lethality in mice (MED = 5 mg/kg ip). This is the first example of an NMDA receptor antagonist that incorporates a tetrazole moiety as an omega-acid bioisostere. These amino acid antagonists are also unique from their phosphonic acid counterparts in that they have a shorter duration of action in vivo. For the treatment of acute disorders such as stroke, where an NMDA antagonist would be administered parenterally, the shorter duration of action may be beneficial, e.g., allowing for better dosage control. The combination of potent NMDA receptor antagonism and a short duration of action may make these compounds useful therapeutic agents in the treatment of a variety of neurological disorders.

• Cu/ <scp>Picolinamides‐Catalyzed</scp> Coupling of (Hetero)aryl Halides with Secondary Phosphine Oxides and Phosphite ^†
  作者：Chao Fang、Bangguo Wei、Dawei Ma

  DOI：10.1002/cjoc.202100354

  日期：2021.11

  Some 4-hydroxy-picolinic acid derived amides were revealed as more efficient ligands for Cu-catalyzed coupling of (hetero)aryl halides with secondary phosphine oxides and phosphites. Only 3—5 mol% CuI and ligands were required to ensure coupling with a number of (hetero)aryl bromides and iodides to complete at 120 oC in 10—20 h.

  一些 4-羟基-吡啶甲酸衍生的酰胺被揭示为更有效的配体，用于（杂）芳基卤化物与仲氧化膦和亚磷酸酯的铜催化偶联。仅需要 3-5 mol% CuI 和配体即可确保与许多（杂）芳基溴化物和碘化物的偶联在 120 o C 下在 10-20 小时内完成。
