Currently used antipsychotics are characterized by multireceptor mode of action. While antagonism of dopamine D₂ receptors is responsible for the alleviation of “positive” symptoms of schizophrenia and the effects at other, particularly serotonergic receptors are necessary for their additional therapeutic effects, there is no consensus regarding an “ideal” target engagement. Here, a detailed SAR analysis in a series of 45 novel azinesulfonamides of cyclic amine derivatives, involving the aryl-piperazine/piperidine pharmacophore, central alicyclic amine and azinesulfonamide groups has led to the selection of (S)-4-((2-(2-(4-(benzo[b]thiophen-4-yl)piperazin-1-yl)ethyl)pyrrolidin-1-yl)sulfonyl)isoquinoline (62). The polypharmacology profile of 62, characterized by partial 5-HT_1AR agonism, 5-HT_2A/5-HT₇/D₂/D₃R antagonism, and blockade of SERT, reduced the “positive”-like, and “negative”-like symptoms of psychoses. Compound 62 produced no catalepsy, demonstrated a low hyperprolactinemia liability and displayed pro-cognitive effects in the novel object recognition task and attentional set-shifting test. While association of in vitro features with the promising in vivo profile of 62 is still not fully established, its clinical efficacy should be verified in further stages of development.

当前使用的抗精神病药的特征在于多受体作用方式。尽管多巴胺D ₂受体的拮抗作用可减轻精神分裂症的“阳性”症状，而对其他（尤其是血清素能受体）的作用对于它们的附加治疗作用是必需的，但对于“理想的”靶标结合尚无共识。在此，对涉及环芳基-哌嗪/哌啶药效团，中心脂环族胺和嗪磺酰胺基团的45种新颖的环胺衍生物的新型嗪磺酰胺进行了详细的SAR分析，导致选择了（S）-4-（（2-（ 2-（4-（苯并[ b ]噻吩-4-基）哌嗪-1-基）乙基）吡咯烷-1-基磺酰基）异喹啉（62）。62的多药理学特征是部分5-HT _1A R拮抗作用，5-HT _2A / 5-HT ₇ / D ₂ / D ₃ R拮抗作用和对SERT的阻断，降低了“阳性”样和“阴性”似精神病的症状。化合物62不产生僵直症，显示出高催乳激素缺乏症，并在新颖的物体识别任务和注意力转移试验中表现出促认知作用。虽然仍未完全确定体外特征与有希望的体内分布相关性62，但其临床疗效应在进一步的开发阶段进行验证。
