title: D-myo-inositol 1,4,5-trisphosphate analogues as useful tools in biochemical studies of intracellular calcium mobilization.
abstract: Two types of structural variants of D-myo-inositol 1,4,5-trisphosphate [Ins(1,4,5)P3] were prepared by a chemoenzymatic route. These 6-O-substituted analogues retained the biological activity of Ins(1,4,5)P3, and were able to elicit Ca2+ release from porcine brain microsomes. Moreover, these derivatives allowed the preparation of Ins(1,4,5)P3-based immunogens and affinity matrix which were successfully applied to the preparation and purification of antibodies against Ins(1,4,5)P3. These antibodies displayed discriminative affinity towards Ins(1,4,5)P3, and provide a useful tool to study intracellular Ca2+ mobilization.
