Synthesis of 5-phosphonate analogues of myo-inositol 1,4,5-trisphosphate: possible intracellular calcium antagonists
摘要:
The racemic 5-phosphonate analogues IV and V of myo-inositol 1,4,5-trisphosphate were readily accessible by bisphosphorylation of the common precursor 6, removal of the p-methoxybenzyl group, phosphonylation and subsequent hydrogenolysis of the benzyl protecting groups. The methylphosphonate analogue IV acted as a calcium antagonist in permeabilized human platelets, whereas the (difluoromethyl)phosphonate V exhibited only very little antagonistic activity.
