The simpler, the better: H3 histamine receptor (H3R) are of interest as therapeutic targets in cognitive and somnolence disorders. Here, lead optimization of H3R inverse agonists bearing a thiazolo[5,4‐c]piperidine group gave rise to a clinical candidate with a much simpler unprecedented benzamide scaffold, displaying decreased hERG activity while maintaining high brain receptor occupancies.
更简单,更好: H 3组胺受体(H 3 R)作为认知障碍和嗜睡症的治疗靶标受到关注。在这里,带有噻唑并[5,4- c ]哌啶基团的H 3 R反向激动剂的前导优化产生了一种临床候选药物,它具有简单得多的前所未有的苯甲酰胺支架,在保持高脑受体占用率的同时,显示出降低的hERG活性。
