  Aza-THIP and related analogues of THIP as GABA C antagonists

  摘要：

  The potency of a series of eight compounds structurally related with 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol (THIP), a potent GABA(A) partial agonist exhibiting GABA(C) rho(1) antagonist effect (K-i = 25 muM), was determined electrophysiologically using homomeric human GABA(C) rho(1) receptors expressed in Xenopus oocytes. Protolytic properties (pK(a) values for the acidic bioisosteric groups) and the presence of steric bulk in the molecules appear to be structural parameters of importance for blockade of the GABA(C) rho(1) receptor. Within this series of moderately potent GABA(C) antagonists, only 4,5,6,7-tetrahydropyrazolo[5,4-c]pyridin-3-ol (Aza-THIP) does not interact delectably with GABA(A) receptors, and Aza-THIP has the potential of being a useful tool for molecular and behavioural pharmacological studies.

  accelerate the rate of oxidation, and accordingly increase the efficiency of brain specific delivery. A multivariate calibration method for in vitro determination of the oxidation rate for the suggested brain specific chemical delivery system is described. The method is based on measurement of individual rates of oxidation of prepared 1, 2‐dihydroisoquinolines, using silver ions to provide the corresponding

  为了克服 1, 2-二氢-N-烷基异喹啉的缓慢氧化，1, 2-二氢异喹啉-N-乙酸衍生物 (3b-d) 被设计和合成为大脑的新化学递送系统 (CDS)。建议衍生物的分子轨道计算表明，这些载体对氧化是稳定的。然而，水解为其相应的阴离子会加快氧化速度，从而提高大脑特异性传递的效率。描述了一种多变量校准方法，用于体外测定建议的大脑特定化学递送系统的氧化速率。该方法基于对制备的 1, 2-二氢异喹啉的单独氧化速率的测量，使用银离子提供相应的四元形式。通过氧化步骤形成的二元混合物的组分（由二氢化合物及其四元形式组成）显示出相当程度的光谱重叠 - 在所有情况下超过 90%。研究中的这些二元混合物的分辨率主要是使用经典最小二乘法分析完成的。测试化合物的动力学氧化数据表明，这些新的 CDS 具有合理的氧化速率，可有效地传递大脑。
