both chemically and biologically diverse, and their biological performance distinctly depends on both the structure of the sesquiterpene lactone-derived scaffolds and the stereochemistry of the pyrrolidine fragment. Biological investigation of the compound collection led to the discovery of a novel chemotype inhibiting Hedgehog-dependent osteoblast differentiation
我们描述了通过结合概念上互补的伪天然产物(伪NP)设计策略和复杂性到多样性环失真方法的形式适应而获得的新的天然产物启发的化合物类别的合成和生物学评估。片段大小的α-亚甲基倍半萜内酯,其支架在形式上可以被视为彼此相关或通过环畸变获得,通过高选择性立体互补1,3-偶极环加成反应与生物碱衍生的吡咯烷片段结合。发现所得的假倍半萜生物碱在化学和生物学上都具有多样性,并且它们的生物学性能明显取决于倍半萜内酯衍生支架的结构和吡咯烷片段的立体化学。对化合物集合的生物学研究发现了一种抑制刺猬依赖性成骨细胞分化的新化学型
