Formation of methylphosphoryl inositol phosphates by extractions that employ methanol

Formation of methylphosphoryl inositol phosphates by extractions that employ methanol.

Fixatives that contain methanol extract an unknown compound from several tissues including the retinas of squid (Loligo). We have determined that the compound probably contains (1) a myo-inositol ring that is phosphorylated in more than one position (including at the 5-hydroxyl), (2) a charged moiety that is not susceptible to alkaline phosphatase, and (3) a methyl group. We have found that the...

SnapShot: Inositol Phosphates

The rapid formation of inositol phosphates in human platelets by thrombin is inhibited by prostacyclin.

The biochemical events underlying the ability of thrombin to enhance the metabolism of inositol phospholipids in human platelets have been investigated using platelets prelabeled with [3H]inositol. Thrombin treatment caused rapid formation of radioactive inositol monophosphate (IP), inositol bisphosphate (IP2), and inositol trisphosphate (IP3) with less marked and more variable changes in the l...

Stereoselective synthesis of inositol phosphates

Pseudomonas putia'a oxidation of benzene affords cis-3,5-cyclohexadiene1,2diol (JJ which serves as a novel precursor for the syntheses of several natural products including (+)-pinitol, (+)-condunto1 F, D-(-)-myo-inositol 1,4,5-trisphosphate and Dmyo-inositol 1-phosphate. The versatility of this approach is further demonstrated by the preparation of other functionalised cyclitol derivatives, in...
