The present invention provides a use for the preparation of an immunopotentiator of a spergualin-related compound represented by the following general formula [I] or a pharmacologically acceptable salt thereof:
H2N- C -NH-X-(CH2)3-CO-NH- C H-CO-NH-R [I] I HN Y
wherein X represents
or -(CH2)n-,
Y represents a hydrogen atom or a hydroxyl or hydroxymethyl group,
n is an integer of 3 or 5, and
R represents -(CH2)4-R, (wherein R, is -NH2 or -OH), -(CH2)3-R2 (wherein R2 is -COOH or -CHO), -(CH2)4-NH-(CH2)3-OH or -(CH2)4-NH-(CH2)2-R2 (wherein R2 is as defined above).
The invention also provides new compounds of the above formula provided that the case wherein X is --(CH2)3- and Y is a hydrogen atom is excluded, and pharmaceutical compositions containing such compounds as active ingredients."
本发明提供了一种由下式通式[I]代表的精蛋白相关化合物或其药理学上可接受的盐制备免疫增强剂的用途:
H2N- C -NH-X-(CH2)3-CO-NH- C H-CO-NH-R [I] I HN Y
其中 X 代表
或-(CH2)n-、
Y 代表氢原子或羟基或羟甲基、
n 是 3 或 5 的整数,以及
R代表-(CH2)4-R,(其中R为-NH2或-OH),-(CH2)3-R2(其中R2为-COOH或-CHO),-(CH2)4-NH-(CH2)3-OH或-(CH2)4-NH-(CH2)2-R2(其中R2如上定义)。
