Abstract
Acid hydrolysis of myo-inositol 1,3,5-orthoesters, apart from orthoformates, exclusively affords the corresponding 2-O-acyl myo-inositol products via a 1,2-bridged five-membered ring dioxolanylium ion intermediate observed by NMR spectroscopy. These C-2-substituted inositol derivatives provide valuable precursors for rapid and highly efficient routes to 2-O-acyl inositol 1,3,4,5,6-pentakisphosphates and myo-inositol 1,3,4,5,6-pentakisphosphate with biologically interesting and anticancer properties. Deuterium incorporation into the α-methylene group of such alkyl ester products (2-O-C(O)CD2R), when the analogous alkyl orthoester is treated with deuterated acid, is established utilizing the novel orthoester myo-inositol 1,3,5-orthobutyrate as an example. Such deuterated ester products provide intermediates for deuterium-labeled synthetic analogues. Investigation into this selective formation of 2-O-ester products and the deuterium incorporation is presented with proposed mechanisms from NMR experiments.

Abstract
![]()
Although adenophostin A (AdA), the most potent agonist
of d-myo-inositol 1,4,5-trisphosphate receptors
(IP3R), is thought to mimic IP3, the relative
roles
of the different phosphate groups and the adenosine motif have not
been established. We synthesized all three possible bisphosphate analogues
of AdA and glucose 3,4-bisphosphate (7, AdA lacking the
2′-AMP). 2′-Dephospho-AdA (6) was prepared
via a novel regioselective dephosphorylation strategy. Assessment
of the abilities of these bisphosphates to stimulate intracellular
Ca2+ release using recombinant rat type 1 IP3R (IP3R1) revealed that 6, a mimic of Ins(4,5)P2, is only 4-fold less potent than IP3, while 7 is some 400-fold weaker and even 3″-dephospho-AdA
(5) is measurably active, despite missing one of the
vicinal bisphosphate groups normally thought to be crucial for IP3-like activity. Compound 6 is the most potent
bisphosphate yet discovered with activity at IP3R. Thus,
adenosine has a direct role independent of the 2′-phosphate
group in contributing toward the potency of adenophostins, the vicinal
bisphosphate motif is not essential for activity at the IP3R, as always thought, and it is possible to design potent agonists
with just two of the three phosphates. A model with a possible adenine–R504
interaction supports the activity of 5 and 6 and also allows a reappraisal of the unexpected activity previously
reported for the AdA regioisomer 2″-phospho-3″-dephospho-AdA 40.

Abstract
Starting from branched para-benzoquinones a practical and highly flexible route is described for the preparation of unsaturated carbapyranoses. The potential of the synthesized galactose analogues to act as competitive inhibitors in lectin-carbohydrate interactions is investigated by means of Surface Plasmon Resonance (SPR) Spectroscopy.

Abstract
A novel, mild, and efficient method was described to introduce a dibenzyl phosphate by ring opening of benzylglycidol mediated by Lewis acids. This methodology was used as a key step for synthesizing the dihydroxyacetone phosphate (DHAP) in only three steps with an overall yield of 74% from the commercially available racemic benzylglycidol.

Abstract
myo-Inositol 1,3,4,5,6-pentakisphosphate (Ins(1,3,4,5,6)P(5)), an inositol polyphosphate of emerging significance in cellular signalling, and its C-2 epimer scyllo-inositol pentakisphosphate (scyllo-InsP(5)) were synthesised from the same myo-inositol-based precursor. Potentiometric and NMR titrations show that both pentakisphosphates undergo a conformational ring-flip at higher pH, beginning at pH 8 for scyllo-InsP(5) and pH 9 for Ins(1,3,4,5,6)P(5). Over the physiological pH range, however, the conformation of the inositol rings and the microprotonation patterns of the phosphate groups in Ins(1,3,4,5,6)P(5) and scyllo-InsP(5) are similar. Thus, scyllo-InsP(5) should be a useful tool for identifying biologically relevant actions of Ins(1,3,4,5,6)P(5), mediated by specific binding sites, and distinguishing them from nonspecific electrostatic effects. We also demonstrate that, although scyllo-InsP(5) and Ins(1,3,4,5,6)P(5) are both hydrolysed by multiple inositol polyphosphate phosphatase (MINPP), scyllo-InsP(5) is not dephosphorylated by PTEN or phosphorylated by Ins(1,3,4,5,6)P(5) 2-kinases. This finding both reinforces the value of scyllo-InsP(5) as a biological control and shows that the axial 2-OH group of Ins(1,3,4,5,6)P(5) plays a part in substrate recognition by PTEN and the Ins(1,3,4,5,6)P(5) 2-kinases.
