A series of 1-substituted 4-amino-1H-pyrazolo[3,4-b]pyridine-5-carboxylic acid esters and amides were synthesized and screened for anxiolytic activity in the shock-induced suppression of drinking (SSD) test. The compounds were also tested for their ability to displace [3H]flunitrazepam (FLU) from brain benzodiazepine (BZ) binding sites. Many compounds were active in these screens and, additionally
合成了一系列的1-取代的4-
氨基-1H-
吡唑并[3,4-b]
吡啶-5-
羧酸酯和酰胺,并筛选了在休克诱导的饮酒抑制(S
SD)试验中的抗焦虑活性。还测试了化合物从大脑苯并二氮杂(
BZ)结合位点置换[3H]
氟硝西m(FLU)的能力。许多化合物在这些筛选中均具有活性,此外,Hill系数显着小于1,并通过[3H] FLU结合分析表明,对1
BZ(
BZ1)受体的选择性高于对2
BZ(
BZ2)受体的选择性。来自不同大脑区域的结果。基于这些化合物的结构活性研究结果,提出了一种假设来解释与脑
BZ受体进行最佳相互作用所必需的结构特征。对最有效的行为活性化合物之一的详细药理评估(27)表明它具有
BZ1选择性。此外,与地西epa相比,在治疗有效剂量下,27种药物具有最小的镇静和
酒精相互作用特性。
