also assayed as inhibitors of GlcCer synthase, because such compounds could find use in the substrate reduction therapy approach to treat lysosomal storage diseases, but these compounds revealed only moderate activity. As efficient pharmacologicalchaperones, new structures such as the di‐C10‐ester constitute leads for the development of therapeutic agents for types2 and 3 Gaucherdisease, the most severe
制备并表征了一系列带有C-连接的二-O-酰基或二-O-烷基甘油基取代基的亚氨木糖醇衍生物。所有设计为葡萄糖基神经酰胺(GlcCer)模拟物的化合物都是溶酶体β-葡萄糖苷酶(葡萄糖脑苷脂酶,GCase)的纳摩尔抑制剂。进一步评估了这些假糖脂中的两种在人Gaucher细胞中增强突变型GCase活性的能力。虽然二ø -己基醚是令人惊讶的缺乏在两个N370S和L444P GCases陪伴活性,二- ö -decanoyl酯是L444P水解酶的一种有效的分子伴侣,其能够通过的因子增加酶的剩余活性的两个浓度很低(50 n M); 尚未观察到对人成纤维细胞中L444P突变的显着影响。在热应激研究中,发现二醚在稳定野生型酶方面比二酯更有效。还测定了四种代表性的假糖脂作为GlcCer合酶的抑制剂,因为此类化合物可在底物还原疗法中用于治疗溶酶体贮积病,但这些化合物仅显示中等活性。作为有效的药理分子伴侣,诸如di-C
