  Use of Small-Molecule Crystal Structures To Address Solubility in a Novel Series of G Protein Coupled Receptor 119 Agonists: Optimization of a Lead and in Vivo Evaluation

  摘要：

  G protein coupled receptor 119 (GPR119) is viewed as an attractive target for the treatment of type 2 diabetes and other elements of the metabolic syndrome. During a program toward discovering agonists of GPR119, we herein describe optimization of an initial lead compound, 2, into a development candidate, 42. A key challenge in this program of work was the insolubility of the lead compound. Small-molecule crystallography was utilized to understand the intermolecular interactions in the solid state and resulted in a switch from an aryl sulphone to a 3-cyanopyridyl motif. The compound was shown to be effective in wild-type but not knockout animals, confirming that the biological effects were due to GPR119 agonism.

  拉帕替尼衍生类似物的水溶性的改善：鉴定人类非洲锥虫病药物开发的喹啉亚胺铅。

  摘要：

  拉帕替尼是一种批准的表皮生长因子受体抑制剂，被用作合成抗非洲锥虫病（HAT）病原体布鲁氏锥虫新药的起点。以前的工作在1（NEU-1953）中达到了高潮，这是通常与水溶性差有关的一系列研究的一部分。在这份报告中，我们介绍了各种药物化学策略，这些策略可用于增加水溶解度和改善理化特性，而又不牺牲抗胰锥虫的药效。为了对锥虫命中的病毒进行分类，建立了一种新的测定方法（总结为杀细胞有效浓度（CEC50）），作为线索选择过程的一部分。增加1的sp3碳含量可得到10e（针对布鲁氏杆菌的EC9为0.19μM，水溶解度为990μM）。对10e的进一步化学探索得到22a，一种锥虫杀喹啉亚胺（EC50：0.013μM；水溶性：880μM； CEC50：0.18μM）。化合物22a在锥虫体感染的小鼠中将寄生虫病降低了109倍；它是HAT药物开发的先进先导。

  an air-stable dianthracenyl monophosphine ligand (diAnthPhos) which can be prepared in two steps from commercially available anthracene derivatives. The ligand exhibits excellent efficiency for palladium-catalyzed coupling reactions. In particular, Miyaura borylation of heterocycle-containing electrophiles can be facilitated employing the diAnthPhos ligand with a broad substrate scope and low catalyst
