A library of dimers and heterodimers of both enantiomers of 2-O-alkylated iminoxylitol derivatives has been synthesised and evaluated on β-glucocerebrosidase (GCase), the enzyme responsible for Gaucher disease (GD). Although the objective was to target simultaneously the active site and a secondary binding site of the glucosidase, the (−)-2-iminoxylitol moiety seemed detrimental for imiglucerase inhibition
已经合成了2- O-烷基化的亚氨木糖醇衍生物的两个对映异构体的二聚体和异二聚体文库,并在β-葡萄糖脑苷脂酶(GCase)上进行了评估,该酶是引起高雪氏病(GD)的酶。尽管目的是同时靶向葡糖苷酶的活性位点和次级结合位点,但(-)-2-亚氨基羟醇部分似乎对伊美苷酶抑制有害,并且在G202R,N370S和L444P成纤维细胞中未获得明显的增强。但是,所有具有至少一种(+)-2- O-烷基亚氨木糖醇的化合物都是纳摩尔范围内的GCase抑制剂,并且在G202R纤维刀片中是显着的GCase活性增强剂,这已通过糖基神经酰胺水平的降低和共定位研究得到证实。 。
