Although amine dehydrogenases (AmDHs) are emerging as attractive biocatalysts for chiral amine synthesis, their synthetic application in structurally diverse arylamines remains challenging, given the limited substrateacceptance. Substrate walking is an effective coevolution strategy to confer targeted substrateacceptance to an enzyme through a stepwise mutagenesis landscape adaptation. Here, based
尽管胺脱氢酶(AmDH)正在成为手性胺合成的有吸引力的生物催化剂,但由于底物接受度有限,它们在结构多样的芳胺中的合成应用仍然具有挑战性。底物行走是一种有效的共同进化策略,通过逐步诱变景观适应赋予酶目标底物接受能力。在此,基于传统的底物行走策略,我们报告了一种类似盾构机的底物行走策略,以快速从芽孢杆菌中进化出F- Bb AmDH ,以获取难以胺化的稠环和连接环芳基酮。合理选择一组苯环位于侧链末端且碳骨架规则延伸的单环芳基酮同系物作为过渡底物。基于过渡底物的活性和特异性增强,鉴定出具有扩展的目标稠环和连接环芳基酮接受性的优质突变体库,从而能够以高达 94% 的产率和 99 的产率合成药物和生物活性化合物相关的芳胺。 % ee ( R ) 或 99:1顺式/反式。基于结构的计算结果提供了对扩大底物接受度来源的分子见解。我们的工作展示了一种简洁的工程工作流程,用于结构多样的底物面板的酶的集体接受进化,并且在酶工程中具有广阔的前景。

Methods, compositions, dosing regimes, and routes of administration for the treatment or prevention of arrhythmias. In these methods, arrythmias (e.g. atrial fibrillation, atrial flutter, early afterdepolarizations and prolongation of QT interval) may be reduced or eliminated by administering ion channel modulating compounds to a subject in need thereof. The ion channel modulating compounds may be cycloalkylamine ether compounds, particularly cyclohexylamine ether compounds. Also described are compositions of ion channel modulating compounds and drugs which induce early afterdepolarizations, prolongation of QT interval and/or Torsades de Pointes.
治疗或预防心律失常的方法、组合物、给药方案和给药途径。在这些方法中,通过对有需要的受试者施用离子通道调节化合物,可减少或消除心律失常(如心房颤动、心房扑动、早期后极化和 QT 间期延长)。离子通道调节化合物可以是环烷基胺醚化合物,特别是环己胺醚化合物。还描述了离子通道调节化合物和药物的组合物,这些组合物会诱发早期后极化、QT间期延长和/或Torsades de Pointes。
