title: Synthesis of analogues of myo-inositol 1,4,5-trisphosphate that contain sulfonamide, sulfate, methylphosphonate, and carboxymethyl groups.
abstract: The syntheses are described of four isosteric racemic myo-inositol 1,4,5-trisphosphate (1) analogues with the phosphate groups replaced by sulfonamide (2), sulfate (3), methylphosphonate (4), and carboxymethyl (5). None of these compounds had any affinity for the IP3 receptor or induced platelet aggregation.
