for the synthesis of racemic 6-deoxy-myo-inositol 1,3,4,5-tetrakisphosphate [6-deoxy-DL-Ins(1,3,4,5)P4] and the chiral antipodes D- and L-6-deoxy-myo-inositol 1,3,4,5-tetrakisphosphate are described here. The racemic tetrakisphosphate was synthesised from DL-1,2-O-isopropylidene-myo-inositol in eight steps. Deoxygenation at C-6 was achieved following the Barton-McCombie procedure. Both chiral tetrakisphosphates
D-肌醇 1,3,4,5-四磷酸 [Ins(1,3,4,5)P4] 从已建立的第二信使 D-肌醇 1,4,5-三磷酸 [Ins( 1,4,5)P4] 在受刺激的细胞中。尽管进行了广泛的研究,特别是关于其在介导细胞 Ca2+ 流入方面的潜在作用,但尚未描述这种磷酸肌醇的确切细胞功能。然而,已经在许多组织中鉴定出结合位点,并且它已显示出与 Ins(1,4,5)P3 协同作用。为了帮助阐明识别和激活受体所必需的 Ins(1,3,4,5)P4 部分的作用机制和结构要求,需要这种四磷酸的结构类似物。外消旋 6-deoxy-myo-inositol 1,3,4,5-tetrakisphosphate [6-deoxy-DL-Ins(1,3,4, 5)P4] 和手性对映体 D-和 L-6-脱氧-肌醇 1,3,4,5-四磷酸在这里进行了描述。外消旋四磷酸是由 DL-1,2-O-异亚丙基-肌醇分八步合成的。按照
