Structural analogs of natural phospholipids

摘要

Structural analogs of natural phospholipids of the general formulae <IMAGE> <IMAGE> +TR <IMAGE> where R1 and R2 represent either hydrogen and/or saturated or unsaturated straight-chain and branched acyl radicals with 2 to 24 C-atoms and R3 an amino group or a substituted amino group of the formula <IMAGE> and n is a number from 1-3, are useful in the preparation of stable liposomes useful as vehicles for pharmaceutical preparations.
