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.
本发明的目的是提供一种透皮制剂,通过 WT1 蛋白衍生的癌症抗原肽更有效地诱导 CTL。
本发明通过使用含有 WT1 蛋白衍生癌症抗原肽和由式(1)表示的
醚类添加剂的透皮制剂,能够更有效地诱导 CTL:
R1-O-R2 (1)
[其中 R1 是具有 8-24 个碳原子的烃基,以及
R2 是由式(2)表示的基团:
或式(3)所代表的基团:
-(CH2CH2O)mH (3)
其中 m 为 1 - 18 的整数]、
其中,添加剂在 20°C 时为液态,与 WT1 蛋白衍生的癌症抗原肽混合。
