  Biological Diversity from a Structurally Diverse Library: Systematically Scanning Conformational Space Using a Pyranose Scaffold

  摘要：

  Success in discovering bioactive peptide mimetics is often limited by the difficulties in correctly transposing known binding elements of the active peptide onto a small and metabolically more stable scaffold while maintaining bioactivity. Here we describe a scanning approach using a library of pyranose-based peptidomimetics that is structurally diverse in a systematic manner, designed to cover all possible conformations of tripeptide motifs containing two aromatic groups and one positive charge. Structural diversity was achieved by efficient selection of various chemoforms, characterized by a choice of pyranose scaffold of defined chirality and substitution pattern. A systematic scanning library of 490 compounds was thus designed, produced, and screened in vitro for activity at the somatostatin (sst(1-5)) and melanin-concentrating hormone (MCH1) receptors. Bioactive compounds were found for each target, with specific chemoform preferences identified in each case, which can be used to guide follow-on drug discovery projects without the need for scaffold hopping.

  Obesity is an increasingly common disease. While antagonism of the melanin-concentrating hormone-1 receptor (MCH-1R) has been widely reported as a promising therapeutic avenue for obesity treatment, no MCH-1R antagonists have reached the market. Discovery and optimization of new chemical matter targeting MCH-1R is hindered by reduced HTS success rates and a lack of structural information about the

  肥胖是一种越来越常见的疾病。虽然已经广泛报道了黑色素浓缩激素-1受体（MCH-1R）的拮抗作用是肥胖治疗的一种有希望的治疗途径，但尚未有MCH-1R拮抗剂进入市场。降低HTS成功率和缺乏有关MCH-1R结合位点的结构信息，阻碍了针对MCH-1R的新化学物质的发现和优化。X射线晶体学和NMR是结构信息的主要实验来源，它们是膜蛋白的非常缓慢的过程，目前不适用于每种GPCR或GPCR-配体复合物。这种情况极大地限制了这些方法“实时”影响GPCR靶标的药物发现过程的能力，因此，迫切需要其他实用且具有成本效益的替代方法。我们在这里提出一种在概念上具有先驱性的方法，该方法将GPCR建模与VAST技术（稳定模板上的多功能组装）的多种糖基化合物的设计，合成和筛选相集成，以提供有关MCH-1R结合位点的结构见解。这种方法为针对GPCR靶标的基于结构的药物发现（SBDD）创建了一种经济高效的新途径。在我们的工
