Potent Prearranged Positive Allosteric Modulators of the Glucagon-like Peptide-1 Receptor

Rosario Scopelliti, Johannes Broichhagen

Drugs that allosterically modulate G protein-coupled receptor (GPCR) activity display higher specificity and may improve disease treatment. However, the rational design of compounds that target the allosteric site is difficult, as conformations required fo ...

Gold-Catalyzed Synthesis of 1,3-Diaminopyrazoles from 1-Alkynyltriazenes and Imines

Kay Severin, Rosario Scopelliti, Loïc Nicolas Jeanbourquin, Farzaneh Fadaei Tirani

A new procedure for the synthesis of highly substituted 1,3-diaminopyrazoles is described. As substrates, we have employed 1-alkynyltriazenes and imines. The formation of pyrazoles was achieved by two-fold C–N coupling reactions in the presence of (JohnPho ...

The Intricate Structural Chemistry of MII2nLn-Type Assemblies

Kay Severin, Rosario Scopelliti, Euro Solari, Philip Pattison, Mathieu Jérémie Marmier, Farzaneh Fadaei Tirani, Giacomo Cecot

The reaction of cis-blocked, square-planar MII complexes with tetratopic N-donor ligands is known to give metallasupramolecular assemblies of the formula M2nLn. These assemblies typically adopt barrel-like structures, with the ligands paneling the sides of ...

A Strategy to Produce High Efficiency, High Stability Perovskite Solar Cells Using Functionalized Ionic Liquid-Dopants

Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Paul Joseph Dyson, Zhaofu Fei, Peng Gao, Farzaneh Fadaei Tirani, Yonghui Lee, Yi Zhang

Functionalized imidazolium iodide salts (ionic liquids) modified with -CH2-CH=CH2, -CH2C equivalent to CH, or -CH2C equivalent to N groups are applied as dopants in the synthesis of CH3NH3PbI3-type perovskites together with a fumigation step. Notably, a so ...

Organometallic Glutathione S-Transferase Inhibitors

Rosario Scopelliti, Paul Joseph Dyson, Emilia Paunescu, Mylène Soudani

A new family of organometallic p-cymene ruthenium(II) and osmium(II) complexes conjugated to ethacrynic acid, a glutathione transferase (GST) inhibitor, is reported. The ethacrynic acid moiety (either one or two) is tethered to the arene ruthenium(II) and ...

PdII2L4-type coordination cages up to three nanometers in size

Kay Severin, Rosario Scopelliti, Matthew David Wise, Suzanne Maria Jansze

The utilization of large ligands in coordination-based self-assembly represents an attractive strategy for the construction of supramolecular assemblies more than two nanometers in size. However, the implementation of this strategy is hampered by the fact ...
