the cyanide group. During the course of synthesis, Staudinger-type reductive cyclization of 1,3-azido carboxylic acid and 1,4-azido alcohol offers a direct route to the five-membered pyrrolidone and pyrrolidine products. The preliminary biological evaluation indicates that the designed pyrrolidine analog is biologically active and its cytotoxic effect is associated with the induction of apoptosis.
基于天然鞘脂的结构,我们设计了杂环鞘氨醇碱基模拟物,其中通过在鞘氨醇碱基的2-氨基和C-4碳原子之间掺入吡咯烷部分来引入构象限制。我们的合成的特征是环硫酸盐与氰化物的区域选择性亲核开环,以及随后对氰化物基团的处理。在合成过程中,1,3-叠氮基羧酸和1,4-叠氮基醇的Staudinger型还原环化为五元吡咯烷酮和吡咯烷产物提供了直接途径。初步的生物学评估表明,设计的吡咯烷类似物具有生物学活性,其细胞毒性作用与细胞凋亡的诱导有关。
