in preclinical candidates (privileged scaffolds). The new compounds were synthesized, tested for their affinity at 5-HT7 and 5-HT1A receptors, and screened for their in vitro stability to microsomal degradation and toxicity. Selected compounds were characterized as 5-HT7 receptor-preferring ligands, endowed with high metabolic stability and low toxicity. Compound 7g emerged as a drug-like 5-HT7 receptor-preferring
最近的临床前研究表明,血清素5-HT7受体的激活具有治疗神经发育障碍(如脆弱X综合征)的潜力,脆弱X综合征是一种以自闭症为特征的罕见疾病。为了向科学界提供多样化的药物样5-HT7受体优先激动剂,我们通过利用临床批准药物或临床前候选药物(特权支架)中存在的结构片段设计了一组新的长链芳基哌嗪。合成了这些新化合物,测试了它们对5-HT7和5-HT1A受体的亲和力,并筛选了它们对微粒体降解和毒性的体外稳定性。所选择的化合物被表征为5-HT7受体优选的配体,具有高代谢稳定性和低毒性。
