assessed on GBA2 selectivity offset against the other glucosylceramide metabolizing enzymes, glucosylceramide synthase (GCS), lysosomal glucosylceramidase (GBA), and the cytosolic retaining β-glucosidase, GBA3. Our work, yielding potent and selective GBA2 inhibitors, also provides a roadmap for the development of high-throughput assays for identifying retaining glycosidase inhibitors by FluoPol-ABPP
人非溶酶体葡萄糖基神经酰胺酶(GBA2)是控制糖脂水平的几种酶之一,其活性与几种人类疾病状态相关。迫切需要设计或发现选择性的GBA2抑制剂作为化学工具和潜在的治疗剂。在这里,我们描述了基于荧光偏振活性的蛋白质谱分析(FluoPol-ABPP)测定法的发展,该测定法可从350多种亚氨基糖文库中快速鉴定GBA2抑制剂。基于FluoPol-ABPP筛选的线索生成聚焦库,并针对与其他葡糖神经酰胺代谢酶,葡糖神经酰胺合酶(GCS),溶酶体葡糖神经酰胺酶(GBA)和胞质保留β-葡糖苷酶GBA3的GBA2选择性偏移进行评估。我们的工作产生了有效的和选择性的GBA2抑制剂,
