The identification of potent and orally active dihydroimidazoisoquinolines as PDE 10A inhibitors is reported. The SAR development led to the discovery of compound 35 as a potent, selective, and orally active PDE10A inhibitor. Compound 35 inhibited MK-801-induced hyperactivity at 3mg/kg and displayed a 10-fold separation between the minimal effective doses for inhibition of MK-801-induced hyperactivity and hypolocomotion in rats.
报告了具有强效和口服活性的二氢咪唑并异喹啉作为 PDE10A 抑制剂的鉴定。通过 SAR 研究发现了化合物 35,它是一种强效、选择性和口服活性的 PDE10A 抑制剂。化合物 35 在 3mg/kg 时抑制 MK-801 诱导的过度活动,并在抑制 MK-801 诱导的过度活动和大鼠的低活动剂量之间表现出 10 倍的分离。
