potential anthrax toxin inhibitors based on the β‐cyclodextrin (βCD) scaffold were developed by exploiting face‐selective CuI‐catalyzed azide–alkyne 1,3‐cycloadditions, amine–isothiocyanate coupling, and allyl group hydroboration–oxidation/hydroxy → amine replacement reactions. The molecular design follows the “symmetry–complementarity” concept between homogeneously functionalized polycationic βCD derivatives
通过利用面选择性Cu I催化的叠氮化物-炔烃1,3-环加成反应,胺-异硫氰酸酯偶联以及烯丙基氢硼化-氧化/开发了三种基于β-环糊精(βCD)支架的潜在炭疽毒素抑制剂新系列。羟基→胺替代反应。分子设计遵循均相官能化的聚阳离子βCD衍生物与保护性抗原(PA)之间的“对称性-互补性”概念,PA是已知形成C 7的炭疽毒素的一种成分致死和浮肿因子利用细胞膜上的对称孔获得细胞溶质的通道。本文报道了一系列阳离子分子的数量,排列和表面位置不同的βCD衍生物的合成和抗毒素活性。这些结果为新候选人对抗炭疽威胁的结构-活动关系发展计划奠定了基础。
