important for glucose homeostasis, and their chemical structure is limited to benzimidazole core. We describe herein our efforts for identification of novel AMPK activator. Our newly designed 4-azaindole derivative 16g exhibited single-digit nM in vitro activity, and chronic treatment with 16g led to dose-dependent improvement in HbA1c as well as decrease in hepatic lipid accumulation in diabetic animal model

, which have valuable pharmacological properties, in particular bind to the AMP-activated protein kinase (AMPK) and modulate its activity. The compounds are suitable for treatment and prevention of diseases which can be influenced by this receptor, such as metabolic diseases, in particular diabetes type 2.

cross-coupling of NH-sulfoximines with (hetero)arylchlorides, as well as bromide and sulfonate electrophiles, that makes use of the air-stable, commercial precatalyst (PhPAd-DalPhos)Ni(o-tol)Cl. Under optimized conditions a diverse electrophile scope is established, including the N-arylation of the pharmaceutical Clozapine. While 5 mol % Ni and 80 °C are commonly employed in this chemistry, successful examples
我们报告了一种使用空气稳定的商用预催化剂 (PhPAd-DalPhos)Ni( o -tol) 使NH -亚砜亚胺与(杂)芳基氯以及溴化物和磺酸盐亲电试剂交叉偶联的通用方法克莱。在优化条件下,建立了多种亲电试剂范围,包括药物氯氮平的N-芳基化。虽然该化学反应通常采用 5 mol% Ni 和 80 °C,但本文也介绍了使用 1 mol% Ni 和/或 25 °C 的成功示例。竞争实验证实了在这些条件下NH-亚磺酰亚胺作为亲核试剂优于伯磺酰胺。
