acetylcholine receptor (mAChR) subtype 5 (M5) represents a novel potential target for the treatment of multiple addictive disorders, including opioid use disorder. Through chemical optimization of several functional high-throughput screening hits, VU6019650 (27b) was identified as a novel M5 orthosteric antagonist with high potency (human M5 IC50 = 36 nM), M5 subtype selectivity (>100-fold selectivity against
毒蕈碱性乙酰胆碱受体 (mAChR) 亚型 5 (M 5 ) 代表了治疗多种成瘾性疾病(包括阿片类药物使用障碍)的新型潜在靶点。通过对几个功能性高通量筛选命中的化学优化,VU6019650 ( 27b ) 被确定为一种新型 M 5正构拮抗剂,具有高效力(人类 M 5 IC 50 = 36 nM)、M 5亚型选择性(对 100 倍以上的选择性) human M 1-4 ) 和在临床前成瘾模型中全身给药的有利物理化学特性。在急性脑切片电生理学研究中,27b阻断了非选择性毒蕈碱激动剂 oxotremorine-M 诱导的腹侧被盖区中脑多巴胺神经元神经元放电率的增加,这是中脑边缘多巴胺能奖励回路的一部分。此外,27b还在不损害一般运动输出的剂量范围内抑制雄性 Sprague-Dawley 大鼠的羟考酮自我给药。
