  摘要：

  我们之前已经报道了2-（酰基氨基）噻吩-3-羧酸甲酯作为GABA B阳性变构调节剂在体外和体内均具有活性，其合成和药理学表征。在当前的工作中，我们描述了基于酰胺基或杂环基团的酯部分的生物等位取代以及作为其刚性类似物的噻吩并[2,3- d ]嘧啶衍生物的合成，合成新化合物。4 H-噻吩并[2,3- d ] [1,3]恶嗪-4-酮被用作合成中间体，以制备其中一些化合物。恶嗪酮11b，16和17的结构X射线晶体学研究确定了这些化合物的存在，这无疑排除了先前为这些化合物所假定的同分异构的β-内酰胺结构。无论是变构还是正构配体，这些新分子均未在GABA B受体上显示出显着活性。

  Synthesis and Pharmacological Characterization of 2-(Acylamino)thiophene Derivatives as Metabolically Stable, Orally Effective, Positive Allosteric Modulators of the GABA_B Receptor

  摘要：

  Two recently reported hit compounds, COR627 and COR628, underpinned the development of a series of 2-(acylamino)thiophene derivatives. Some of these compounds displayed significant activity in vitro as positive allosteric modulators of the GABA(B) receptor by potentiating GTP gamma S stimulation induced by GABA at 2.5 and 25 mu M while failing to exhibit intrinsic agonist activity. Compounds were also found to be effective in vivo, potentiating baclofen-induced sedation/hypnosis in DBA mice when administered either intraperitoneally or intragastrically. Although displaying a lower potency in vitro than the reference compound GS39783, the new compounds 6, 10, and 11 exhibited a higher efficacy in vivo: combination of these compounds with a per se nonsedative dose of baclofen resulted in shorter onset and longer duration of the loss of righting reflex in mice. Test compounds showed cytotoxic effects at concentrations comparable to or higher than those of GS39783 or BHF177.

  previously reported the synthesis and the pharmacological characterization of a family of methyl 2-(acylamino)thiophene-3-carboxylates as GABAB positive allosteric modulators active both in vitro and in vivo. In the present work, we describe the synthesis of new compounds based on the bioisosteric replacement of the ester moiety with amido or heterocyclic groups as well as of thieno[2,3-d]pyrimidine derivatives
