Phosphodiesterase 10A (PDE10A) inhibition has recently been identified as a potential mechanism to treat multiple symptoms that manifest in schizophrenia. In order to facilitate preclinical development and support key proof-of-concept clinical trials of novel PDE10A inhibitors, it is critical to discover positron emission tomography (PET) tracers that enable plasma concentration/PDE10A occupancy relationships
最近发现磷酸二酯酶10A(PDE10A)抑制是治疗精神分裂症中出现的多种症状的潜在机制。为了促进临床前开发并支持新型PDE10A抑制剂的关键概念验证临床试验,至关重要的是发现正电子发射断层扫描(PET)示踪剂,以使血浆浓度/ PDE10A占有率关系能够在结构多样的PDE10A的物种间建立。抑制剂。在这封信中,我们描述了如何优化高通量筛选结果以提供[ 11 C ] MK - 8193(8j),这是一种PET示踪剂,可用于确定大鼠和恒河猴中一系列结构多样的PDE10A抑制剂的血浆浓度/ PDE10A占用率关系。
