  Polycyclic aryl- and heteroarylpiperazinyl imides as 5-HT1A receptor ligands and potential anxiolytic agents: synthesis and structure-activity relationship studies

  摘要：

  A series of polycyclic aryl- and heteroarylpiperazinyl imides were prepared and tested in various receptor-binding and behavioral tests. Parameters measured included in vitro inhibition of D2 and 5-HT1A receptor binding, inhibition of apomorphine (APO) induced stereotyped and climbing behavior, and activity in blocking conditioned avoidance responding (CAR). Several compounds demonstrated moderate to high affinity for the 5-HT1A receptor binding site; compounds 27 and 36 containing the serotonin mimetic (o-methoxyphenyl)piperazinyl moiety and compounds 42 and 50 containing the 2-pyrimidinylpiperazinyl moiety displayed the highest affinity, being equal to that of the 5-HT1A agonist 8-OH-DPAT (Ki = 1-1.3 nM). In addition to affinity at 5-HT1A binding sites, many compounds were active in blocking CAR. Compound 34, 2-[4-[4-(2-pyrimidinyl)-1-piperazinyl]butyl]hexahydro-4,7-etheno-1H- cyclobut[f]isoindole-1,3(2H)-dione, demonstrated 3 times the activity of buspirone, blocking CAR in rats with an AB50 of 13 mg/kg. It also displayed high affinity for the 5-HT1A receptor (Ki = 16 nM), which is at least 20 times higher than its affinity for D2 (Ki = 345 nM) and 5-HT2 (Ki = 458 nM) receptors. Compound 34 was selected for further preclinical and pharmacokinetic evaluations for possible development as an anxiolytic agent. Structure-activity relationships within this series are discussed.

  Psychotropic agents: synthesis and antipsychotic activity of substituted .beta.-carbolines

  摘要：

  A series of novel substituted beta-carbolines was synthesized and tested for potential antipsychotic activity. Several compounds displayed moderate antipsychotic activity in vitro and in vivo as determined by relevant receptor binding assays and behavioral tests. The effect of substituents on antipsychotic activity was examined. The beta-carbolines 10 and 19 containing 2-(2-pyridinyl)ethyl and 2-(2-quinolinyl)ethyl side chains were the most potent analogues, blocking discrete trial conditioned avoidance responding in rats with AB50's of 23 and 10 mg/kg, respectively. Both showed moderate activity at the D2 receptor sites, but they lacked oral activity. In contrast, the beta-carboline 13 containing the 4-(4-pyridinyl)butyl side chain exhibited oral activity in the discrete trial conditioned avoidance screen with an AB50 of 31 mg/kg. Most compounds did not antagonize apomorphine-induced stereotyped behavior, which is indicative of low potential for extrapyramidal side effect (EPS) liability.

  Several novel substituted tetrahydro- and hexahydro-1,2-benzisothiazol-3-one 1,1-dioxides and thiadiazinones were prepared and examined in a series of in vitro and in vivo tests to determine their pharmacological profile. Most compounds were orally active in blocking the conditioned avoidance response (CAR) but did not antagonize apomorphine-induced stereotyped behavior. Several compounds demonstrated

  its potent and selective profile in preclinical psychopharmacological tests. It blocked CAR in rats with an AB50 of 14 mg/kg po, showed weak affinity for the D2 receptor site (Ki = 104 nM), and showed differential potency in antagonizing apomorphine-induced stereotyped behavior (ED50 = 11 mg/kg ip) and climbing behavior (ED50 = 4 mg/kg ip). Such activities are suggestive of antipsychotic efficacy combined

  合成了几种新颖的取代γ-咔啉，并在一系列体外和体内药理试验中进行了研究，以确定潜在的抗精神病活性。大多数化合物在阻断大鼠条件性回避反应（CAR）方面具有口服活性，但没有拮抗阿扑吗啡诱导的刻板印象行为。化合物17（Wy-47,384）是一种具有3-（3-吡啶基）丙基侧链的γ-咔啉，由于其在临床前心理药理学测试中的有效和选择性特征，因此被选作非典型抗精神病药。它在AB50为14 mg / kg po的大鼠中阻断CAR，对D2受体位点的亲和力较弱（Ki = 104 nM），并且在拮抗阿扑吗啡定型行为方面表现出不同的效力（ED50 = 11 mg / kg ip）和攀爬行为（ED50 = 4 mg / kg ip）。
