  COMPLEX AND STRUCTURALLY DIVERSE COMPOUNDS

  摘要：

  这项发明提供了一种新颖、通用且简便的策略，用于创造具有高结构和立体化学复杂性的小分子。该方法的方面包括系统地应用于快速将易得的天然产物转化为具有多样分子结构的结构复杂化合物的环系统失真反应。通过评估化学性质，包括sp3碳的分数、ClogP和立体中心的数量，这些化合物被证明比标准筛选集合中的化合物显着更复杂和多样化。这种方法是通过来自三个不同结构类别的天然产物（赤霉酸、肾上腺酮和奎宁）来展示的，并描述了将该策略应用于任何合适的天然产物的方法。

• A ring-distortion strategy to construct stereochemically complex and structurally diverse compounds from natural products

  High-throughput screening is the dominant method used to identify lead compounds in drug discovery. As such, the makeup of screening libraries largely dictates the biological targets that can be modulated and the therapeutics that can be developed. Unfortunately, most compound-screening collections consist principally of planar molecules with little structural or stereochemical complexity, compounds that do not offer the arrangement of chemical functionality necessary for the modulation of many drug targets. Here we describe a novel, general and facile strategy for the creation of diverse compounds with high structural and stereochemical complexity using readily available natural products as synthetic starting points. We show through the evaluation of chemical properties (which include fraction of sp3 carbons, ClogP and the number of stereogenic centres) that these compounds are significantly more complex and diverse than those in standard screening collections, and we give guidelines for the application of this strategy to any suitable natural product. An approach for the construction of complex and diverse compound libraries is described, whereby natural products are altered through a series of ring system distortion reactions. The compounds produced have markedly different physiochemical properties from those in standard screening collections and thus could offer advantages in the search for lead molecules that can be developed into drug candidates.

  高通量筛选是药物发现过程中确定先导化合物的主要方法。因此，筛选库的组成在很大程度上决定了可调节的生物靶点和可开发的治疗方法。遗憾的是，大多数化合物筛选库主要由结构或立体化学复杂性较低的平面分子组成，这些化合物无法提供调节许多药物靶点所需的化学功能排列。在这里，我们介绍了一种新颖、通用和简便的策略，即利用现成的天然产物作为合成起点，创造出具有高结构和立体化学复杂性的多种化合物。我们通过对化学性质（包括 sp3 碳的比例、ClogP 和立体中心的数量）的评估表明，这些化合物的复杂性和多样性明显高于标准筛选集合中的化合物。本文介绍了一种构建复杂多样化合物库的方法，即通过一系列环系统畸变反应改变天然产物。生成的化合物与标准筛选库中的化合物具有明显不同的理化性质，因此在寻找可开发成候选药物的先导分子方面具有优势。

  The invention provides a novel, general, and facile strategy for the creation of small molecules with high structural and stereochemical complexity. Aspects of the methods include ring system distortion reactions that are systematically applied to rapidly convert readily available natural products to structurally complex compounds with diverse molecular architectures. Through evaluation of chemical properties including fraction of sp3 carbons, ClogP, and the number of stereogenic centers, these compounds are shown to be significantly more complex and diverse than those in standard screening collections. This approach is demonstrated with natural products (gibberellic acid, adrenosterone, and quinine) from three different structural classes, and methods are described for the application of this strategy to any suitable natural product.

  Natural 3 beta-hydroxy-gibberellins, GA(3) (gibberellic acid) (1), GA(1) (2), and GA(4) (3), were directly converted to 3 alpha-hydroxy-gibberellins, 3-epi-GA(3) (4), -GA(1) (5) and -GA(4) (6), by highly alpha-biased equilibration through retro- and re-aldol mechanism with potassium tert-butoxide in tert-butyl alcohol, and to 3-oxo-gibberellins, 3-oxo-GA(95) (7), -GA(20) (8) and -GA(9) (9), by catalytic oxidation with tetrapropylammonium perruthenate.
