The discovery of a series of thiophenephenylsulfonamides as positive allosteric modulators (PAM) of α7 nicotinic acetylcholine receptor (α7 nAChR) is described. Optimization of this series led to identification of compound 28, a novel PAM of α7 nicotinic acetylcholine receptor (α7 nAChR). Compound 28 showed good in vitro potency, with pharmacokinetic profile across species with excellent brain penetration
描述了一系列噻吩苯基磺酰胺作为α7烟碱乙酰胆碱受体(α7nAChR)的正变构调节剂(PAM)的发现。通过优化该系列化合物,可以鉴定出化合物28,这是一种新型的α7烟碱乙酰胆碱受体(α7nAChR)PAM。化合物28表现出良好的体外效能,具有跨物种的药代动力学特征,具有出色的大脑渗透性和停留时间。在非常低的剂量水平下,化合物28在新的目标和社会认可任务中,在时间延迟和东pol碱引起的健忘范例中,强烈逆转了情景记忆/工作记忆中的认知缺陷。此外,化合物28在1期临床试验中显示出优异的安全性,并正在评估轻度至中度阿尔茨海默氏病患者作为单一疗法的疗效和安全性。
