Discovery and Development of <i>N</i>-[4-(1-Cyclobutylpiperidin-4-yloxy)phenyl]-2-(morpholin-4-yl)acetamide Dihydrochloride (SUVN-G3031): A Novel, Potent, Selective, and Orally Active Histamine H<sub>3</sub> Receptor Inverse Agonist with Robust Wake-Promoting Activity
histamine H3 receptor (H3R), physicochemical properties, and pharmacokinetics in rats resulted in identification of N-[4-(1-cyclobutyl-piperidin-4-yloxy)phenyl]-2-(morpholin-4-yl)acetamide dihydrochloride (17v, SUVN-G3031) as a clinical candidate. Compound 17v is a potent (hH3R Ki = 8.73 nM) inverse agonist at H3R with selectivity over other 70 targets, Compound 17v has adequate oral exposures and
在大鼠中对组胺H3受体(H3R)的体外亲和力,理化性质和药代动力学指导下的一系列化学优化导致鉴定了N- [4-(1-环丁基-哌啶丁-4-基氧基)苯基] -2 -(吗啉-4-基)乙酰胺二盐酸盐(17v,SUVN-G3031)作为临床候选药物。化合物17v在H3R上是一种强效(hH3R Ki = 8.73 nM)反向激动剂,对其他70个靶标具有选择性。化合物17v在大鼠和狗中均具有足够的口服暴露量和良好的消除半衰期。它显示出高的受体占有率和明显的促醒作用,并减少了Orexin-B萨泊林损伤的大鼠的快速眼动睡眠,支持了其在治疗人类睡眠障碍中的潜在治疗作用。剂量比有效剂量高出几倍,对运动活性没有影响。它没有hERG和磷脂病的问题。已经成功完成了对动物的安全性,耐受性和药代动力学的第一阶段评估,以及对动物的长期安全性研究,而无需担心进一步的开发。

Bis(het)aryl-1,2,3-triazole quinuclidines as α7 nicotinic acetylcholine receptor ligands: Synthesis, structure affinity relationships, agonism activity, [18F]-radiolabeling and PET study in rats
and nine of them exhibited Ki values below nanomolar concentrations. The best scores were always obtained when the 5-phenyl-2-thiophenyl core was attached to the triazole. The selectivity of these compounds towards the nicotinic α4β2 and serotoninergic 5HT3 receptors was assessed and their brain penetration was quantified by the preparation and in vivo evaluation of two [18F] radiolabelled derivatives

blockade of the PD-1/PD-L1 immune checkpoint pathway with small molecules is an emerging immunotherapeutic approach. A novel series of 4-phenylindoline derivatives were synthesized, and their inhibitory activity against the PD-1/PD-L1 protein-protein interaction (PPI) was evaluated through a homogenous time-resolved fluorescence (HTRF) assay. Among them, A20 and A22 exhibited potent activity with IC50
