(OGA) has emerged as a promising therapeutic approach to treat tau pathology in neurodegenerative diseases such as Alzheimer’s disease and progressive supranuclear palsy. Beginning with carbohydrate-based lead molecules, we pursued an optimization strategy of reducing polar surface area to align the desired drug-like properties of potency, selectivity, high central nervous system (CNS) exposure, metabolic
O-GlcNAcase(OGA)的抑制已成为治疗神经退行性疾病(如阿尔茨海默氏病和进行性核上性麻痹)的tau病理学的一种有前途的治疗方法。从以碳水化合物为基础的铅分子开始,我们奉行一种减少极性表面积的优化策略,以使所需的类药性与效能,选择性,高中枢神经系统(CNS)暴露,代谢稳定性,有利的药代动力学和体内稳健性保持一致药效学反应。在这里,我们描述了导致(3a R,5 S,6 S,7 S,7 R,7a R)-5-(二氟甲基)-2-(乙基氨基)-3a,6,7的鉴定的药物化学和药理研究,7a-四氢-5 H-吡喃并[3,2 - d ]噻唑-6,7-二醇42(MK-8719),一种具有出色的CNS渗透性的强效选择性OGA抑制剂,已被开发到人类首次进入I期临床试验。
