enzimidazol-4-yl)phenoxy]methyl}-1H-pyrazol-4-yl)pyridin-2(1H)-one (38b). Compound 38b exhibited good selectivity against other PDEs, and oral administration of 38b improved visual-recognition memory deficit in mice at doses of 0.001 and 0.003 mg/kg in the novel object recognition test. ASP9436 (sesquiphosphate of 38b) may therefore be used for the treatment of schizophrenia with a low risk of phototoxicity
我们合成了几种作为PDE10A抑制剂的联芳基衍生物,以防止2- [4-([1-甲基-4-(吡啶-4-基)-1] H-吡唑-3-基]氧基}甲基)苯基]喹啉的光毒性(1)发现联芳基的能量最小构象和共平面构象之间的能量差有助于促进联芳基化合物的光毒性潜力的预测。在3T3 NRU测试中,用N-甲基苯并咪唑取代1的喹啉环增加了这种能量差并防止了光毒性。进一步优化确定了1-甲基-5-(1-甲基-3-[4-(1-甲基-1 H-苯并咪唑-4-基)苯氧基]甲基} -1 H-吡唑-4-基)吡啶- 2(1小时)-一(38b)。化合物38b显示出对其他PDE的良好选择性,并且在新颖的物体识别测试中,口服施用38b改善了小鼠的视觉识别记忆缺陷,剂量为0.001和0.003mg / kg。因此,ASP9436(倍半磷酸盐的38b)可用于治疗具有低光毒性风险的精神分裂症。
