  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.

  vivo. M1, cleavage product of the methyl ester group at C-3, revealed in vitro an unusual mechanism of metabolism by a NADPH-dependent route and, in vivo, it maintained high and persistent levels in plasma, which could represent a potential pharmacokinetic and toxicological issue. In the novel set of COR659 analogues, those bearing branched alkyl substituents on the ester group, showed an improved in vitro

  我们报告了一项对COR659（1）的体外I期代谢研究，COR659是一种2-酰基氨基噻吩衍生物，能够抑制大鼠酒精和巧克力的自我给药，可能是通过对GABA B受体的正变构调节和对大麻素的拮抗作用/反向激动作用CB 1受体。鉴于已将噻吩环C-3处的甲基酯基团鉴定为代谢弱点，我们还报告了化学优化项目，旨在平衡一组3取代COR659类似物在体内和体外的代谢稳定性与代谢稳定性。 高效液相色谱串联和高分辨率质谱用于表征大鼠COR659的体外代谢和体内药代动力学。体外[ 35 S] GTP γ S结合于刺激的GABA测定乙和CB 1点用酒精和巧克力自身给药实验的受体，结合在大鼠中，采用以评估这种新颖的组类似物的药理学特性，使用COR659作为参考化合物。 在肝微粒体温育中发现了COR659的八种代谢物；通过与合成参考标准品比较确定了其中的两个（M1，M2）。M2是噻吩环C-5处甲基的氧化产物，在体外是主
