  The insulin secretory action of novel polycyclic guanidines: Discovery through open innovation phenotypic screening, and exploration of structure–activity relationships

  摘要：

  We report the discovery of the glucose-dependent insulin secretogogue activity of a novel class of polycyclic guanidines through phenotypic screening as part of the Lilly Open Innovation Drug Discovery platform. Three compounds from the University of California, Irvine, 1-3, having the 3-arylhexahydropyrrolo[1,2-c] pyrimidin-1-amine scaffold acted as insulin secretagogues under high, but not low, glucose conditions. Exploration of the structure-activity relationship around the scaffold demonstrated the key role of the guanidine moiety, as well as the importance of two lipophilic regions, and led to the identification of 9h, which stimulated insulin secretion in isolated rat pancreatic islets in a glucose-dependent manner.

  Described are methods for preparing a deuterated aldehyde using with a photocatalyst and a hydrogen atom transfer agent in a H2O free solvent comprising D2O and an organic solvent under an inert gas. The methods may be used to convert a wide variety of aldehydes (e.g., aryl, alkyl, or alkenyl aldehydes) to C-1 deuterated aldehydes under mild reaction conditions.

  描述了一种使用光催化剂和氢原子转移剂在不含H2O的溶剂中（包括D2O和有机溶剂）在惰性气体下制备氘代醛的方法。这些方法可用于在温和的反应条件下将各种醛类（如芳基、烷基或烯基醛）转化为C-1氘代醛。

  2-propanol. The copper catalysts are not only inexpensive compared to rhodium complexes, but they also exhibit better functional group compatibility with aromatic aldehydes and ketones. Indeed very high yields were obtained for the formation of styrenes containing nitro, trifluoromethyl, amino, and ester groups, as well as for pyridine-, pyrrole-, and indole-substituted alkenes.

  （NHC）-Cu（NHC = N-杂环卡宾）配合物在三甲基甲硅烷基重氮甲烷，三苯基膦和2-丙醇的存在下有效催化了各种脂肪族和芳香族醛和酮的甲基化反应。与铑配合物相比，铜催化剂不仅价格便宜，而且与芳族醛和酮的官能团相容性也更好。实际上，对于形成含有硝基，三氟甲基，氨基和酯基的苯乙烯，以及吡啶，吡咯和吲哚取代的烯烃，都获得了很高的产率。
