Towards the aim of creating a functional mimic of isopenicillin N synthase, a small molecule designed to coordinate around iron(II) and model the enzyme active site has been prepared in nine synthetic steps from 2,6-bis(hydroxymethyl)pyridine, (S)-(+)-mandelic acid and pivaldehyde. One aspartate, two histidines and a water ligand in the natural enzyme are replaced by an α-hydroxy acid, pyridine and
努力创造功能性模拟物的异青霉素N合成酶,小分子设计铁(II),以协调周围的目的和酶活性位点在九个合成步骤制备从2,6-双(羟甲基)吡啶,建模(小号)-(+)-扁桃酸和四醛。天然酶中的一个天冬氨酸,两个组氨酸和一个水配体在模型化合物中被α-羟酸,吡啶和苯胺取代。另外,设计用来模拟酶底物的游离硫醇δ-(1-α-氨基己二酰基)-1-半胱氨酰-d-缬氨酸通过三碳链与配体连接。我们假设在分子氧的存在下,这种合成的配体与铁(II)之间形成的复合物将显示出与异青霉素N合酶活性位点相似的氧化化学反应。
