  The catalytic union of amides, sulfonamides, anilines, imines, or N-heterocycles with a broad spectrum of electronically and sterically diverse alkyl bromides has been achieved via a visible-light-induced metallaphotoredox platform. The use of a halogen abstraction-radical capture (HARC) mechanism allows for room temperature coupling of C(sp3)-bromides using simple Cu(II) salts, effectively bypassing

  Herein, we describe a method for treatment of diabetes and other disorders classified as Metabolic Syndrome. The invention provides novel AMP Deaminase (AMPD) inhibitors comprising novel indazole and benzotriazole derivatives including a phosphorous containing derivative, a carboxylic acid, or an amino acid ester prodrug. The invention also provides support for a novel mechanism of action for the existing drug metformin: direct inhibition of the enzyme AMPD. The inhibition of AMPD in turn activates AMP Kinase, known to be linked to the action of metformin. The invention also makes novel use of a double inhibitor assay allowing identification of selective AMPD inhibitors over ADA inhibitors. The new inhibitors, structurally distinct from metformin, offer selectivity that may obviate side effects known for metformin itself, providing new benefits for diabetes and Metabolic Syndrome.

  在这里，我们描述了一种治疗糖尿病和其他归类为代谢综合征的疾病的方法。该发明提供了一种新型的AMP脱氨酶（AMPD）抑制剂，包括新型的吲唑和苯并三唑衍生物，其中包括含磷衍生物、羧酸或氨基酸酯前药。该发明还支持现有药物二甲双胍的一种新颖作用机制：直接抑制AMPD酶。抑制AMPD反过来激活AMP激酶，已知与二甲双胍的作用有关。该发明还首次使用了一种双重抑制剂分析，允许识别对ADA抑制剂具有选择性的AMPD抑制剂。这些新抑制剂在结构上与二甲双胍不同，提供的选择性可能消除二甲双胍本身已知的副作用，为糖尿病和代谢综合征带来新的益处。
