We have identified and extensively investigated the photochem. activation and reaction of a hydroxyquinone-derived phenyliodonium ylide in the presence of visible light using experiment and theory.

Ismael, Aya;Skrydstrup, Troels;Bayer, Annette research published 《 Carbonylative Suzuki-Miyaura couplings of sterically hindered aryl halides: synthesis of 2-aroylbenzoate derivatives》, the research content is summarized as follows. A carbonylative approach to the synthesis of diversely substituted 2-aroylbenzoate esters ArC(O)R¹ (Ar = 2-methoxyphenyl, thiophen-2-yl, 2-naphthyl, etc.; R¹ = 2-methoxycarbonyl-6-methylphenyl, 2-methoxycarbonylphenyl, 2-methoxycarbonyl-4,5-dimethoxyphenyl, etc.) featuring a new protocol for the carbonylative coupling of aryl bromides R¹Br with boronic acids ArB(OH)₂ and a new strategy to favor carbonylative over non-carbonylative reactions were developed. Two different synthetic pathways – (i) the alkoxycarbonylation of 2-bromo benzophenones R²C₆H₄C(O)(2-BrC₆H₅) (R² = 2-F, 4-F, 3-OMe, 4-OMe) and (ii) the carbonylative Suzuki-Miyaura coupling of 2-bromobenzoate esters – were evaluated. The latter approach provided a broader substrate tolerance, and thus it was the preferred pathway. Here observed that 2-substituted aryl bromides were challenging substrates for carbonylative chem. favoring the non-carbonylative pathway. However, it is found that carbonylative Suzuki-Miyaura couplings can be improved by slow addition of the boronic acid, suppressing the unwanted direct Suzuki coupling and, thus increasing the yield of the carbonylative reaction.

Iorio, Maria Teresa;Vogel, Florian Daniel;Koniuszewski, Filip;Scholze, Petra;Rehman, Sabah;Simeone, Xenia;Schnuerch, Michael;Mihovilovic, Marko D.;Ernst, Margot research published 《 GABAA receptor ligands often interact with binding sites in the transmembrane domain and in the extracellular domain-can the promiscuity code be cracked?》, the research content is summarized as follows. Many allosteric binding sites that modulate gamma aminobutyric acid (GABA) effects have been described in heteropentameric GABA type A (GABA_A) receptors, among them sites for benzodiazepines, pyrazoloquinolinones and etomidate. Diazepam not only binds at the high affinity extracellular “canonical” site, but also at sites in the transmembrane domain. Many ligands of the benzodiazepine binding site interact also with homologous sites in the extracellular domain, among them the pyrazoloquinolinones that exert modulation at extracellular α+/β- sites. Addnl. interaction of this chemotype with the sites for etomidate has also been described. We have recently described a new indole-based scaffold with pharmacophore features highly similar to pyrazoloquinolinones as a novel class of GABAA receptor modulators. Contrary to what the pharmacophore overlap suggests, the ligand presented here behaves very differently from the identically substituted pyrazoloquinolinone. Structural evidence demonstrates that small changes in pharmacophore features can induce radical changes in ligand binding properties. Anal. of published data reveals that many chemotypes display a strong tendency to interact promiscuously with binding sites in the transmembrane domain and others in the extracellular domain of the same receptor. Further structural investigations of this phenomenon should enable a more targeted path to less promiscuous ligands, potentially reducing side effect liabilities.

Axl and Mer are a members of the TAM (Tyro3-Axl-Mer) family of receptor tyrosine kinases, which, when activated, can promote tumor cell survival, proliferation, migration, invasion, angiogenesis, and tumor-host interactions. Chronic inhibition of Mer leads to retinal toxicity in mice. Therefore, successful development of an Axl targeting agent requires ensuring that it is safe for prolonged treatment. Here, to clarify whether enzyme inhibition of Mer by a small mol. leads to retinal toxicity in mice, we designed and synthesized Axl/Mer inhibitors and Axl-selective inhibitors. We identified an Axl/Mer dual inhibitor 28a, which showed retinal toxicity at a dose of 100 mg/kg in mice. Subsequent derivatization of a pyridine derivative led to the discovery of a pyrimidine derivative, 33g, which selectively inhibited the activity of Axl over Mer without retinal toxicity at a dose of 100 mg/kg in mice. Addnl., the compound displayed in vivo anti-tumor effects without influencing body weight in a Ba/F3-Axl isogenic s.c. model.

Hwang, Seunghae;Kim, Hyun-seung;Ryu, Ji Heon;Oh, Seung M. research published 《 N-(α-ferrocenyl)ethylphthalimide as single redox couple for non-aqueous flow batteries》, the research content is summarized as follows. To establish highly soluble single redox couple for non-aqueous flow batteries, N-(α-ferrocenyl)ethylphthalimide (α-FcEtPI) is derived from a promising single redox couple, N-ferrocenylphthalimide (FcPI), by inserting an α-Me group between the ferrocenyl and phthalimide moieties. The resulting material (α-FcEtPI) shows the maximum solubility of 0.81 M in 1.0 M tetrabutylammonium tetrafluoroborate (TBABF₄) in 1,3-dioxolane at 25 °C. This notable increase in solubility (vs. 0.3 M for FcPI) is attributed to the disruptive effect of the α-Me group on mol. packing in a solid state. α-FcEtPI exhibits two stable redox reactions at E_1/2 = 0.01 V and -1.97 V (vs. Fc/Fc⁺), thus functioning as a single redox couple with working voltage (E_wk) of 1.98 V. Considering the solubility and working voltage, the theor. energy d. of α-FcEtPI is calculated as 21.06 W h L^-1 (vs. 7.8 W h L^-1 for FcPI). The cell data of 0.6 M α-FcEtPI in 1 M TBABF₄ in 1,3-dioxolane electrolytes, indicates remarkably high Coulombic efficiency (97.8%) and excellent cycle retention.
