Parallel synthesis and antileishmanial activity of ether-linked phospholipids

The synthesis and antileishmanial activity of 18 edelfosine analogues are described. Compounds were obtained in parallel combining solid phase and solution phase synthesis. The most active analogue is characterized by the octadecyl group in position 2 of the glycerol chain. Considering that this substitution determines the loss of antitumor activity, a different mechanism of antileishmanial action can be hypothesized.
