The subject matter described herein is directed to Ferroportin inhibitor compounds of Formula I and pharmaceutical salts thereof, methods of preparing the compounds, pharmaceutical compositions comprising the compounds and methods of administering the compounds for prophylaxis and/or treatment of diseases caused by a lack of hepcidin or iron metabolism disorders, particularly iron overload states, such as thalassemia, sickle cell disease and hemochromatosis.
receptors for anions described use halogen bonding binding sites solely in the anionrecognition process; only a few examples report the study of anion receptors in which the halogen bonding interaction has been used in combination with any other non-covalent interaction. With the aims to extend the knowledge in the behaviour of this kind of mixed receptors, we report here the synthesis and the anion recognition
The utilization of anions to induce the formation of self-assembled supramolecular polymers in solution is an undeveloped area of host–guest chemistry. We report in this manuscript a comparative study of two tripodal anion receptors by hydrogen or halogen bonding interactions to form self-assembled supramolecular structures induced by the presence of anions. DOSY NMR and DLS experiments provided evidence
利用阴离子来诱导溶液中自组装的超分子聚合物的形成是主体-客体化学的未开发领域。我们在这份手稿中报告了通过氢或卤素键相互作用形成阴离子导致的自组装超分子结构的两个三脚架阴离子受体的比较研究。DOSY NMR和DLS实验提供了证据为超分子结构的形成在两个卤素和氢键供体溶液用H 2 PO 4 -阴离子。使用热力学模型获得的成核常数和伸长常数表明聚合物遵循等渗机理生长。发射的研究表明,只有卤键供体受体与H之间的超分子聚合物的形成2 PO 4 -阴离子导致受激准分子发光带的外观。

the basic anion. The association constant values of the halogen-bonding complexes in a competitive solvent CD3CN/MeOD (8/2) mixture with H2PO4– and SO42– anions are higher than those found for the hydrogen-bonding counterpart. In contrast, in the less competitive CH3CN solvent higher binding affinity for anions corresponds to the hydrogen-bonding receptor 72+·2PF6–. In addition, the receptor 62+·2PF6–
已经制备了基于两臂咪唑鎓的阴离子受体。中心的2,7-二取代的萘环具有两个具有中心2-溴咪唑鎓或氢键合的咪唑鎓受体的光敏蒽端基封端的侧臂。组合发射和1 H和31项P NMR研究中的各种阴离子的存在下进行显示,只HP 2 ö 7 3-,H 2 PO 4 -,SO 4 2-和F -的阴离子促进显着的变化。卤素受体6 2 + ·2PF 6 –用作H的选择性荧光分子传感器2 PO 4 -阴离子的,因为只有这阴离子促进蒽准分子发射带的外观,而它保持在其他检测的阴离子的存在不变。此外,该卤素受体通过在碱性阴离子作用下脱溴后转变为相应的双咪唑酮,可作为HP 2 O 7 3-阴离子的化学计量器。竞争性溶剂CD 3 CN / MeOD(8/2)与H 2 PO 4 –和SO 4 2–的混合物中卤素键络合物的缔合常数值阴离子高于氢键对应的阴离子。相反,在竞争性较低的CH 3 CN溶剂中,与阴离子的较高结合亲和力对应于氢键受体7

The anion‐templated synthesis of a halogen‐bonding catenane, which recognizes chloride and bromide ions solely by halogen bonding, is described. The catenane's ability to optically sense halide anions using fluorescence spectroscopy is demonstrated.
