A method for preparing plasmalogens and derivatives thereof represented by Formula B, wherein R1 and R2 are similar or different, derived from fatty acids; R3 is selected from hydrogen and small alkyl groups. The synthetic route involves production of novel cyclic plasmalogen precursors of Formula A and their conversion to plasmalogens and plasmalogen derivatives of Formula B. Also disclosed is the therapeutic use of plasmalogens and derivatives thereof as produced by the synthetic route of the present invention.

13
C labeled cyclic plasmalogen precursor of Formula A, and conversion of the precursor to a plasmalogen of Formula B. These plasmalogens may potentially be useful in the determination of both the mechanism of action as well as the fate of plasmalogens in the body.
An object of the present invention is to provide a transdermal preparation showing more efficient induction of CTL by a WT1 protein-derived cancer antigen peptide.
The present invention enables more efficient CTL induction by applying a transdermal preparation containing a WT1 protein-derived cancer antigen peptide, and an ether-type additive represented by the formula (1):
R1-O-R2 (1)
[wherein R1 is a hydrocarbon group having 8 - 24 carbon atoms, and
R2 is a group represented by the formula (2):
or a group represented by the formula (3):
-(CH2CH2O)mH (3)
wherein m is an integer of 1 - 18],
wherein the additive is liquid at 20°C, to a WT1 protein-derived cancer antigen peptide.
