Neutralsphingomyelinase 2 (nSMase2) catalyzes the cleavage of sphingomyelin to phosphorylcholine and ceramide, an essential step in the formation and release of exosomes from cells that is critical for intracellular communication. Chronic increase of brain nSMase2 activity and related exosome release have been implicated in various pathological processes, including the progression of Alzheimer’s disease
中性鞘磷脂酶 2 (nSMase2) 催化鞘磷脂裂解为磷酸胆碱和神经酰胺,这是细胞外泌体形成和释放的重要步骤,对细胞内通讯至关重要。大脑 nSMase2 活性的慢性增加和相关的外泌体释放与各种病理过程有关,包括阿尔茨海默病 (AD) 的进展,使 nSMase2 成为可行的治疗靶点。最近,我们鉴定了苯基 ( R )-(1-(3-(3,4-二甲氧基苯基)-2,6-二甲基咪唑并[1,2- b ]哒嗪-8-基)吡咯烷-3-基)氨基甲酸酯1 ( PDDC),第一个具有良好药效学和药代动力学 (PK) 参数的 nSMase2 抑制剂,包括大量的口服生物利用度、脑渗透和显着抑制体内外泌体从脑中释放。在此,我们展示了1 (PDDC)在 AD 小鼠模型中的功效,并详细介绍了 70 种类似物的广泛构效关系 (SAR) 研究,揭示了几种对 nSMase2 具有相似或更高活性且具有良好药代动力学特性的类似物。
