    Automated Design of Macrocycles for Therapeutic Applications: From Small Molecules to Peptides and Proteins
    摘要:
    Macrocycles and cyclic peptides are increasingly attractive therapeutic modalities as they often have improved affinity, are able to bind to extended protein surfaces, and otherwise have favorable properties. Macrocyclization of a known binder may stabilize its bioactive conformation and improve its metabolic stability, cell permeability, and in certain cases oral bioavailability. Herein, we present implementation and application of an approach that automatically generates, evaluates, and proposes cyclizations utilizing a library of well-established chemical reactions and reagents. Using the three-dimensional (3D) conformation of the linear molecule in complex with a target protein as the starting point, this approach identifies attachment points, generates linkers, evaluates their geometric compatibility, and ranks the resulting molecules with respect to their predicted conformational stability and interactions with the target protein. As we show here with prospective and retrospective case studies, this procedure can be applied for the macrocyclization of small molecules and peptides and even PROteolysis TArgeting Chimeras (PROTACs) and proteins.

    噻唑基肽抗生素GE2270 A的简明全合成。
    摘要:
    由N-叔丁氧羰基保护的缬氨酸以最长的20步线性序列合成了有效的抗生素噻唑基肽GE2270 A,总产率为4.8%。关键策略是通过从2,6-二溴-3-碘吡啶开始的连续交叉偶联反应组装2,3,6-三取代吡啶核。通过3-锌的2,6-二溴吡啶的Negishi交叉偶联将完整的Southern片段安装在三噻唑的2-碘噻唑末端(87%)。在通过另一个Negishi交叉偶联金属化成锌试剂后,以截短的2-溴噻唑-4-羧酸叔丁酯形式引入代表分子北部的C-6处的取代基。整个序列的决定性步骤是将大环化成29元大环内酰胺,这是通过发生在吡啶核的C-2处的分子内Stille交叉偶联进行的,以75%的收率提供所需的产物。通过在代表GE2270 A东部的复杂二噻唑片段与3,6-二取代的2-溴吡啶之间的酰胺键形成(87%)获得所需的锡烷。最终步骤包括将丝氨酸-脯氨酸酰胺二肽附着到分子的北部(65%),形成恶唑啉环和甲硅烷基醚脱保护(总体占55%)。

    Circles and lines: Synthesis of isosteric analogues of QZ59Se‐SSS to inhibit the efflux activity of human P‐glycoprotein (P‐gp) resulted in cyclic trimer and linear trimer compounds as the most potent in the series. These compounds can be further optimized by replacing the thiazole unit with privileged fragments.
