antipsychotics display similar affinity for both D2 (D2R) and D3 (D3R) receptors, and they likewise act as 5-HT2A receptor antagonists. They provide therapeutic benefit for positive symptoms, but no marked or consistent improvement in neurocognitive, social cognitive or negative symptoms. Since blockade of D3 and 5-HT6 (5-HT6R) receptors enhances neurocognition and social cognition, and potentially improves
所有临床使用的抗精神病药均对D 2(D2R)和D 3(D3R)受体表现出相似的亲和力,并且它们同样充当5-HT 2A受体拮抗剂。它们为阳性症状提供治疗益处,但在神经认知,社会认知或阴性症状方面没有明显或持续的改善。由于阻断D 3和5-HT 6(5-HT6R)受体可增强神经认知和社交认知,并可能改善不良症状,因此改善精神分裂症治疗的一种有前途的方法将是开发优先作用于D3R与D2R的药物识别5-HT6R。从高亲和力的5-HT6R配体I和II开始,我们确定了化合物11a和14b,它们具有5-HT6R配体的作用,对D3R的选择性高于D2R。
