Truncated triterpene saponin analogues containing a trisaccharide or tetrasaccharide ester are disclosed. Also disclosed are pharmaceutical compositions comprising truncated saponin analogues and synthetic methods of producing the truncated saponin analogues. Another aspect of the present application relates to a method for immunizing a subject, comprising administering to the subject the pharmaceutical composition comprising a minimal saponin analogue and an antigen.

tetrasaccharide domain revealed that a trisaccharide variant is equipotent to QS-21, while the corresponding disaccharide and monosaccharide congeners are more toxic and less potent, respectively. Modification of the acyl chain domain in the trisaccharide series revealed that a terminal carboxylic acid is well-tolerated while a terminal amine results in reduced adjuvant activity. Acylation of the terminal amine

promise of QS-21adjuvant is curtailed by several factors, including its scarcity, difficulty in purification to homogeneity, dose-limiting toxicity, and chemical instability. Here, we report the design, synthesis, and evaluation of chemically stable synthetic saponins. These novel, amide-modified, non-natural substances exhibit immunopotentiating effects in vivo that rival or exceed that of QS-21 in evaluations
