title: Synthesis and biological activities of (4,6-di-O-phosphonato-beta-D-mannopyranosyl)-methylphosphonate as an analogue of 1L-myo-inositol 1,4,5-trisphosphate.
abstract: The synthesis of the alpha and beta anomers of the title compound (1) was accomplished from D-mannose. In the key step, the phosphonate analogues of the mannopyranosyl phosphates were prepared by a direct Wadsworth-Emmons condensation of a protected mannose derivative (8) with tetraethyl methylenebisphosphonate under two-phase conditions. In vitro bioassays have shown that the beta anomer (1a) is a potent inhibitor of Ins(1,4,5)P3 3-kinase and inhibits other enzymes.
