The present invention provides a process for synthesizing a glycopeptide having the structure: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 are each independently H, OH, OR.sup.1, NH.sub.2, NHCOR.sup.i, F, CH.sub.2 OH, CH.sub.2 OR.sup.i, or a substituted or unsubstituted linear or branched chain alkyl, arylalkyl or aryl group, where R.sup.i is H, CHO, CO.sub.2 R.sup.ii, a linear or branched chain alkyl, arylalkyl or aryl group, or an oligosaccharide moiety, etc., wherein R.sub.0 is H, a linear or branched chain alkyl, arylalkyl or aryl group; wherein R.sub.10 is a substituted or unsubstituted linear or branched chain acyl, arylacyl or aroyl group; wherein R.sub.11\x9bx! represents X amino acid side-chains, and denotes position from the N-terminus, and R.sub.13\x9by! represents Y amino acid side-chains, and denotes position from the C-terminus, wherein a, b, c, h, i, j, r, s and t are each independently an integer between about 0 and about 3; wherein m and n are each independently an integer between about 0 and about 5; and wherein x, x'(N), y and y'(N) are each independently an integer between about 0 and,about 25; such glycopeptides being useful as a vaccine for inducing antibodies to human breast cancer cells in an adjuvant therapy therefor.
本发明提供了一种合成具有以下结构的糖肽的方法:##STR1## 其中R.sub.1、R.sub.2、R.sub.3、R.sub.4、R.sub.5、R.sub.6、R.sub.7和R.sub.8分别独立地为H、OH、OR.sup.1、NH.sub.2、NHCOR.sup.i、F、CH.sub.2 OH、CH.sub.2 OR.sup.i或取代或未取代的线性或支链烷基、芳基烷基或芳基,其中R.sup.i为H、CHO、CO.sub.2 R.sup.ii、线性或支链烷基、芳基烷基或芳基,或寡糖基;其中R.sub.0为H、线性或支链烷基、芳基烷基或芳基;其中R.sub.10为取代或未取代的线性或支链酰基、芳基酰基或芳基基;其中R.sub.11\x9bx!代表X个氨基酸侧链,表示从N-末端的位置,R.sub.13\x9by!代表Y个氨基酸侧链,表示从C-末端的位置,其中a、b、c、h、i、j、r、s和t分别独立地为约0到约3之间的整数;其中m和n分别独立地为约0到约5之间的整数;其中x、x'(N)、y和y'(N)分别独立地为约0到约25之间的整数;这样的糖肽可用作在佐剂治疗中诱导人乳腺癌细胞抗体的疫苗。
