The synthesis of phosphatidylinositol analogues, 6-deoxy Ins 1-(1,2-di- O -palmitoyl- sn -glycero)phosphate and 4,5-bisphosphate derivatives is presented. Two series of phosphonate isosters, 6-deoxy Ins(1)-butylphosphonate and 6-deoxy Ins(1)- C -methylenephosphonate as well as its 4,5-bisphosphate analogue were also prepared. All phosphoinositide analogues were obtained from cyclohexanone polyol derived from the d -galactose. Modification of charge distribution at position 1 of PtdIns and InsP derivatives, by replacement of a POH group by an alkyl substitution or a PC bond, resistant to cleavage by lipases, could induce inhibition of activity at further strategic enzymatic levels of the inositide cascade. |
