We have designed and synthesized ceramide mimics with a pseudo cyclic framework that can be converted to ‘dimeric’ sphingomyelins and glycosphingolipids for potential components of artificial rafts. These molecules are characterized by the presence of (i) two hydrophilic head groups, (ii) a covalently bonded hydrocarbon chain, and (iii) two untethered alkyl chains. Self-assembling of a ceramide mimic into nanorods is briefly discussed.
Modification of neutral (isoelectric) liposomes to anionic liposomes by phospholipase A2: the use of macrocyclic 1,2-dotriacontanedioyl-sn-glycero-3-phosphocholine
1,2-Dotriacontanedioyl-sn-glycero-3-phosphocholine (dTPC) has been synthesized; liposomes containing dTPC were converted rapidly into anionicliposomes at pH 7 by the action of phospholipaseA2, retaining the vesicular structure and exposing the CO2H groups of the lysolipids on the membrane surface.
