Orthogonally protected chiral myo-inositol derivatives are important intermediates for higher order myo-inositol-containing compounds. Here, the use of the immobilized enzyme Novozym 435 to efficiently catalyze the acetylation of the 5R configured enantio

Synthesis of first generation non-hydrolysable C-phosphonate GPI analogs, viz., 6-O-(2-amino-2-deoxy-α-d-glucopyranosyl)-d-myo-inositol-1-O-(sn-3,4- bis(palmitoyloxy)butyl-1-phosphonate) 23a and 6-O-(2-amino-2-deoxy-α-d- glucopyranosyl)-d-myo-inositol-1-O-(sn-2,3-bis(palmitoyloxy)propyl-1- phosphonate) 23b, is reported. The target compounds were synthesized by the coupling of α-pseudodisaccharide 21 with phosphonic acids 18a and 18b respectively in quantitative yield followed by de-protection. These synthetic C-phosphonate GPI-probes were resistant to phosphatidylinositol specific phospholipase C (PI-PLC) and also showed moderate inhibition of the enzyme activity.

Stereoselective α-glycosylation of C(6)-hydroxyl myo-inositols via nickel catalysis - Application to the synthesis of GPI anchor pseudo-oligosaccharides
McConnell, Matthew S.,Mensah, Enoch A.,Nguyen, Hien M.
, p. 146 - 152 (2013/11/06)
Glycosylphosphatidyl inositol (GPI) anchors play a key role in many eukaryotic biological pathways. Stereoselective synthesis of GPI anchor analogues have proven to be critical for probing the biosynthesis, structure, and biological properties of these co

The borondipyrromethene (BODIPY) labeled new glycosylphosphatidylinositol (GPI) molecules were synthesized as cellular probes to study the chemical basis of microdomain organization of GPI-anchored proteins and cholesterol in plasma membrane. The synthesi

A facile and effective method was developed for large-scale syntheses of myo-inositol derivatives with the 1,2,6-O-positions differentiated from each other and from other positions as well. The syntheses started from methyl α-d-glucopyranoside, and the ke
Synthesis of phosphatidylinositol mannosides (PIMs)
Stadelmaier, Andreas,Schmidt, Richard R.
, p. 2557 - 2569 (2007/10/03)
Two strategies towards the synthesis of phosphatidylinositol mannosides (PIMs) were elaborated which permit selective access to the O-1-, O-2-, and the O-6 position of the myo-inositol residue. Starting materials are 1,2:5,6- and 1,2:4,5-di-O-cyclohexylid
First total synthesis of a GPI-anchored peptide
Xue, Jie,Shao, Ning,Guo, Zhongwu
, p. 4020 - 4029 (2007/10/03)
A GPI-anchored dipeptide of sperm CD52 antigen was prepared through a convergent synthesis. First, the dipeptide with its C-terminus free and the GPI with its nonreducing end phosphoeth-anolamine bearing a free amino group were synthesized separately. Then, the two building blocks were coupled with use of EDC/HOBt as the condensation reagent. Finally, the GPI-anchored peptide was deprotected to give the target molecule 1.
Convergent synthesis of an inner core GPI of sperm CD52
Xue, Jie,Guo, Zhongwu
, p. 2015 - 2018 (2007/10/03)
An inner core of the GPI anchor of sperm CD52 antigens was synthesized by a highly convergent process using specially modified inositol, glucosamine and phospholipid as key building blocks. This paper also presents a new and efficient procedure to prepare
An effective strategy for the synthesis of 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-chiro- and -D-myo-inositol 1-phosphate related to putative insulin mimetics
Jaramillo,Chiara,Martin-Lomas
, p. 3135 - 3141 (2007/10/02)
Two glycosylinositol phosphates related to putative insulin mimetics, 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-chiro-inositol 1-phosphate (1) and 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol 1-phosphate (2), have been synthesized from selectively protected and enantiomerically pure D-chiro- and myo-inositol derivatives. The D-chiro-inositol unit was prepared in a multigram scale from D-glucose using the Ferrier's carbocyclization route, and it was transformed into the corresponding myo epimer by an oxidation-reduction sequence. The trichloroacetimidate method was applied efficiently for the key glycosylation of the inositol derivatives.
