progression. The development of nonbisphosphonate inhibitors can provide molecular tools for validating hFPPS as a therapeutic target for tauopathy-associated neurodegeneration. A multistage screening protocol led to the identification of a new monophosphonate chemotype that bind in an allosteric pocket of hFPPS. Optimization of these compounds could lead to human therapeutics that block tau metabolism
人法呢基焦磷酸合酶(hFPPS)是哺乳动物类异戊二烯的守门人,是双膦酸酯类药物的主要靶标。双膦酸盐具有不良的“类药物”性质,并且主要在治疗骨骼疾病方面有效。最近的研究表明,hFPPS与包括阿尔茨海默氏病(AD)在内的各种非骨骼疾病有关。进行尸检确认的AD受试者中hFPPS基因的单核苷酸多态性和mRNA水平的分析,并确定了hFPPS与人脑中磷酸化tau(P-Tau)水平之间的遗传联系。P-Tau水平升高与AD进展密切相关。非双膦酸盐抑制剂的开发可以提供分子工具,以验证hFPPS作为与tauopathy相关的神经变性的治疗靶标。多阶段筛选方案导致鉴定新的结合在hFPPS变构口袋中的单膦酸酯化学型。这些化合物的优化可能会导致人类治疗药物阻断tau代谢并阻止神经退行性疾病的发展。
