binding to the active site, stabilizing the native conformation of GC in the neutral pH environment of the endoplasmic reticulum (ER), enabling its trafficking from the ER to the Golgi and on to the lysosome. The mutated GC fold is generally stable in the lysosome after pharmacological chaperone dissociation, owing to the low pH environment for which the fold was evolutionarily optimized and the high
溶酶体葡糖脑苷脂酶(GC)活性不足引起的高雪氏病是最常见的溶酶体贮积病。临床上重要的GC突变酶通常具有降低的比活性和降低的溶酶体浓度,后者是由于折叠和运输受到损害。我们和其他人已证明,药理分子伴侣通过结合至活性位点,稳定内质网(ER)的中性pH环境中GC的天然构象,使其从ER转运到高尔基体并持续到其上,从而协助GC折叠变体。溶酶体。药理分子伴侣解离后,突变的GC折叠在溶酶体中通常是稳定的,这是因为在低pH环境中进化了折叠,并且折叠的底物浓度高,使GC能够将葡萄糖基神经酰胺水解为葡萄糖和神经酰胺。这项研究的假设是,我们可以结合来自不同化学系列的GC药理分子伴侣结构-活性关系,以提供有效的新型分子伴侣,其包含在活性位点结合的碳水化合物样亚结构和在附近口袋中结合的疏水性亚结构。我们将异黄酮和2,5-脱水-2,5-亚氨基-D-葡萄糖醇活性位点结合的亚结构与疏水性烷基金刚烷基酰胺结合在一起,以提供新
