The beta-1 adrenergic receptor (ADRB1) is a promising therapeutic target intrinsically involved in the cognitive deficits and pathological features associated with Alzheimer's disease (AD). Evidence indicates that ADRB1 plays an important role in regulating neuroinflammatory processes, and activation of ADRB1 may produce neuroprotective effects in neuroinflammatory diseases. Novel small molecule modulators
β-1肾上腺素能受体(ADRB1)是一种有前途的治疗靶标,本质上与阿尔茨海默氏病(AD)相关的认知缺陷和病理特征有关。有证据表明,ADRB1在调节神经炎症过程中起重要作用,并且激活ADRB1可能在神经炎症疾病中产生神经保护作用。ADRB1的新型小分子调节剂经设计具有高度的脑渗透性,并对具有部分激动活性的G蛋白具有功能选择性,可作为药理学工具和潜在的先导分子用于进一步的临床前开发具有巨大的价值。本研究描述了我们正在进行的努力,以发现对AD和神经炎性疾病具有潜在治疗价值的ADRB1功能选择性部分激动剂,从而鉴定了STD-101-D1分子。作为ADRB1的功能选择性激动剂,STD-101-D1对G蛋白信号产生部分激动活性,其EC50值在低纳摩尔范围内,但与无偏见激动剂异丙肾上腺素相比,参与的β-arrestin很少。STD-101-D1还在体内和体外均抑制由脂多糖(LPS)诱导的肿瘤坏死因子α(
