Síntese e avaliação biológica de novas saponinas imunoactivas=

QS21 is a natural saponin extracted with water from the bark of endemic trees of South America which has been shown to play a key role as vaccine adjuvant. The aim of this study was to determine if simpler synthetic analogues of QS-21 could induce similar advantageous immune responses. For this purpose we designed and synthesized both the cholestanyl- and amirinyl-3-β-O-(β-D-xylopyranosyl)-(1 →3)-[(β-D-galactop...
