  Synthesis of enantiopure free and N-benzyloxycarbonyl-protected 3-substituted homotaurines from naturally occurring amino acids

  摘要：

  Enantiopure N-benzyloxycarbonyl-protected and free 3-substituted homotaurines were synthesized from naturally occurring amino acids via N-benzyloxycarbonyl protection, Arndt-Eistert homologation, reduction, esterification with thioacetic acid, and oxidation with performic acid. The current method is a convenient, practical, and salt-free method for the synthesis of enantiopure 3-substituted homotaurine with moderate to good yields. (C) 2014 Elsevier Ltd.

  Didemnins A, B, and C were efficiently prepared in a stereocontrolled manner, producing the common macrocycle and, in a separate step, introducing the substituents on the amino group of L-threonine as optically pure units. We envisaged that disconnections between L-leucine and the HIP group (2S,4S) and between L-threonine and isostatine (3S,4R,5S) would afford two units: a HIP-isostatine unit (I) and

  promise of QS-21 adjuvant 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

  抗肿瘤和抗病毒疫苗的成功通常需要使用佐剂，这种物质可显着增强对共同施用抗原的免疫反应。只有少数佐剂具有足够的效力和可接受的临床研究毒性。QS-21 是一种很有前景的佐剂，它是一种皂苷天然产物，是许多癌症和传染病疫苗临床试验的首选免疫增强剂。然而，QS-21 佐剂的治疗前景受到多种因素的限制，包括其稀缺性、难以纯化至均质、剂量限制性毒性和化学不稳定性。在这里，我们报告了化学稳定的合成皂苷的设计、合成和评估。这些新颖的、酰胺改性的、在 GD3-KLH 黑色素瘤结合疫苗的评估中，非天然物质在体内表现出与 QS-21 相媲美或超过 QS-21 的免疫增强作用。这些新型皂苷的高度收敛合成制剂为发现用于专门定制疫苗疗法的改进分子佐剂开辟了新途径。
