Dipeptides of the formula: ##STR1## in which R-CO represents a fatty acid residue and the symbols R.sub.1, which are identical or different, represent hydroxyl, amino or alkoxy containing 1 to 4 carbon atoms, which is optionally substituted by phenyl or nitrophenyl, it being understood that the alanine is in the L form and the glutamic acid or derivative thereof is in the D form, and their salts are immunological adjuvants and immunostimulants. They may be made using methods known per se in peptide chemistry and may be incorporated in pharmaceutical compositions.
公式为:##STR1## 的二肽,其中R-CO代表脂肪酸残基,符号R.sub.1(相同或不同)代表含有1至4个碳原子的羟基、氨基或烷氧基,可以选择性地被苯基或硝基苯基取代,其中丙氨酸为L型,谷氨酸或其衍生物为D型,它们的盐是免疫佐剂和免疫刺激剂。它们可以使用已知的肽化学方法制备,并可以纳入制药组合物中。
