Synthesis of Novel Lysophosphatidylcholine Analogues Using Serine as Chiral Template

Abstract

Four novel lysophosphatidylcholine (lysoPC) analogues, (S)-N-stearoyl-O-phosphocholineserine methyl ester [(S)-1a], (R)-1-lyso-2-stearoylamino-2-deoxy-sn-glycero-3-phosphatidylcholine [(R)-2a], (R)-N-stearoyl-O-phosphocholineserine methyl ester [(R)-1b], and (S)-1-lyso-2-stearoyl-amino-2-deoxy-sn-glycero-3-phosphatidylcholine [(S)-2b], were synthesized starting from serine as a chiral template. These synthetic compounds exhibited greatly enhanced hyphal transition inhibitory activity in Candida as compared to the natural lysoPC.
