Disclosed herein are β-glucosidase (GCase) chaperones and methods of using GCase chaperones in an individual in need thereof. GBA1 mutations lead to GCase deficiency and substrate accumulation, causing Gaucher disease. Currently, no FDA or EMA-approved therapeutic for neuronopathic Gaucher disease is available. Improved GCase activity in brain cells using a chaperone may reduce substrate accumulation and associated pathology. Disclosed herein are novel non-inhibitory chaperone compounds of GCase that have properties of a central nervous system drug. Those compounds effectively restored mutant GCase activity by stabilizing protein and enhancing lysosomal localization and may be useful for chaperone therapy to treat neuronopathic Gaucher disease and likely to Parkinson's disease.
本文公开了β-葡萄糖苷酶(GCase)合剂以及在有需要的个体中使用GCase合剂的方法。GBA1 突变导致 GCase 缺乏和底物积累,从而引起戈谢病。目前,还没有经 FDA 或 EMA 批准的治疗神经病变性戈谢病的药物。使用伴侣剂改善脑细胞中 GCase 的活性可减少底物积累和相关病理。本文公开了具有中枢神经系统药物特性的新型非抑制性 GCase 伴合剂化合物。这些化合物通过稳定蛋白质和加强溶酶体定位,有效地恢复了突变型 GCase 的活性,可用于治疗神经病性戈谢病和可能的帕金森病的伴侣疗法。
