of an early intermediate in the biosynthetic pathway of glycosylphosphatidylinositol (GPI) membrane anchors. 1-D-6-O-(2-Amino-2-deoxy-alpha-D-glucopyranosyl)-myo-inositol 1-(1,2-di-O-octyl-sn-glycerol 3-phosphate) has also been prepared as a substrate analogue. Biological evaluation of the analogues 23 and 24 revealed that they are neither substrates nor inhibitors of GPI biosynthetic enzymes in the
1-D-6-O-(2-氨基-2-脱氧-α-D-吡喃葡萄糖基)-2-O-辛基-肌醇1-(1,2-二-O-十六烷酰基-sn-甘油3 -磷酸酯(23)和相应的2-O-十六烷基-D-肌醇化合物24已经被制备为糖基磷脂酰肌醇(GPI)膜锚的生物合成途径中的早期中间体的底物类似物。1-D-6-O-(2-氨基-2-脱氧-α-D-吡喃葡萄糖基)-肌醇1-(1,2-二-O-辛基-sn-甘油3-磷酸酯)制备为底物类似物。对类似物23和24的生物学评估表明,它们在人(HeLa)无细胞系统中既不是GPI生物合成酶的底物也不是抑制剂,而是在无锥虫锥虫无细胞系统中GPI生物合成不同阶段的有效抑制剂。
