Vinyl fluorides play an important role in drug development as bioisosteres for peptide bonds and are found in a range of bioactive molecules. The discovery of safe, general and practical procedures to prepare vinyl fluorides from readily available precursors remains a synthetic challenge. The metal-free hydrofluorination of alkynes constitutes an attractive though elusive strategy for their preparation. Here we introduce an inexpensive and easily-handled reagent that enabled the development of simple and scalable protocols for the regioselective hydrofluorination of alkynes to access both the E and Z isomers of vinyl fluorides. These conditions were suitable for a diverse collection of alkynes, including several highly-functionalized pharmaceutical derivatives. Computational and experimental mechanistic studies support C-F bond formation through vinyl cation intermediates, with the ( E )- and ( Z )-hydrofluorination products forming under kinetic and thermodynamic control, respectively.Background and aim of the study Cardiac wounds have been described for centuries and still remain to be fatal. For a long period of time, the suturing of a myocardial laceration was thought to be absolutely impossible if not sacrilege. Methods It is only at the end of the 19th century that pioneers decided to defy such a dogma in desperate cases. Results Nowadays, it seems obvious that a cardiac stab wound requires emergent surgery whenever possible. Conclusions The story of cardiac wounds highlights nicely the change of mind that is required to accept progress and new procedures in medicine.We report the two-step hysteretic Fe(II) spin crossover (SCO) effect achieved in programmed layered Cs[Fe(3-CNpy)2] [Re(CN)8]·H2O (1) assembly consisting of cyanido-bridged FeII-ReV square grid sheets bonded by Cs+ ions. The presence of two non-equivalent FeII sites and the conjunction of 2-D bimetallic coordination network with non-covalent interlayer interactions involving Cs+, [ReV(CN)8]3- ions, and 3-CNpy ligands, leads to the occurrence of two steps of thermal SCO with strong cooperativity giving a double thermal hysteresis loop. The resulting spin transition phenomenon could be tuned by an external pressure giving the room temperature range of SCO as well as by visible light irradiation inducing an efficient recovery of the high spin FeII state at low temperatures. Ruboxistaurin concentration In this report, we prove that octacyanidorhenate(V) ion is an outstanding metalloligand for inducing of cooperative multi-step, multi-switchable FeII SCO effect.Reliance upon exception points to prioritize children for liver transplantation (LT) stems from concerns that the Pediatric End-Stage Liver Disease (PELD) score underestimates mortality. Renal dysfunction and serum sodium disturbances are negative prognosticators in adult LT candidates and various pediatric populations, but are not accounted for in PELD. We retrospectively evaluated the impact of these parameters in predicting 90-day waitlist death/deterioration amongst pediatric patients ( less then 12-years) listed for isolated LT in the United States between Feb 2002-June 2018. Amongst 4,765 patients, 2,303 (49.3%) were transplanted, and 231 (4.8%) died or deteriorated beyond transplantability within 90-days of listing. eGFR (HR 1.09 per 5-unit decrease, 95%CI 1.06-1.10), and dialysis (HR 7.24, 95%CI 3.57-14.66) were univariate predictors of 90-day death/deterioration (p less then 0.001). The long-term benefit of LT persisted in patients with renal dysfunction, with LT as a time-dependent covariate conferre upon non-standard exceptions.We report the breast cancer stem cell (CSC) potency of two nickel(II)-3,4,7,8-tetramethyl-1,10-phenanthroline complexes, 1 and 3, containing the non-steroidal anti-inflammatory drugs (NSAIDs), naproxen and indomethacin, respectively. The nickel(II) complexes, 1 and 3 kill breast CSCs and bulk breast cancer cells in the micromolar range. Notably, 1 and 3 display comparable or better potency towards breast CSCs than salinomycin, an established CSC-active agent. The complexes, 1 and 3 also display significantly lower toxicity towards non-cancerous epithelial breast cells than breast CSCs or bulk breast cancer cells (up to 4.6-fold). Mechanistic studies suggest that 1 and 3 downregulate cyclooxygenase-2 (COX-2) in breast CSCs and kill breast CSCs in a COX-2 dependent manner. Furthermore, the potency of 1 and 3 towards breast CSCs decreased upon co-treatment with necroptosis inhibitors (necrostatin-1 and dabrafenib), implying that 1 and 3 induce necroptosis, an ordered form of necrosis, in breast CSCs. As apoptosis resistance is a hallmark of CSCs, compounds like 1 and 3, which potentially provide access to alternative (non-apoptotic) cell death pathways could hold the key to overcoming hard-to-kill CSCs. To the best of our knowledge, 1 and 3 are the first compounds to be associated to COX-2 inhibition and necroptosis induction in CSCs.Heteroatom-doped polymers or carbon nanospheres have attracted a broad research interest because of their fascinating properties. However, rational synthesis of these nanospheres with controllable uniform morphologies, small particle sizes, and well-designed functionalities is still a great challenge. Herein, we develop an approach to construct cross-linked polyphosphazene nanospheres with tunable hollow structures via a facile template-free one-step method. As comonomers, hexachlorocyclotriphosphazene provides N and P atoms, tannic acid can coordinate with metal ions, and the replaceable third comonomer can endow the materials with various properties. After the carbonization, N/P-doped mesoporous carbon nanospheres were obtained. In addition to the hollow structure, small particle size (~50 nm), and high surface area (411.60 m 2 g -1 ), atomic structural characterizations confirmed that the single atom transition metal sites ( i.e. , Co-N 2 P 2 ) were uniformly dispersed in the carbon shell containing N and P dual coordination. The electrochemical measurements and theoretical simulations revealed the superior oxygen reduction reaction performance of the obtained Co-N 2 P 2 active sites. This work provides a solution for fabricating diverse heteroatom-containing polymer nanospheres and their derived single metal atom doped carbon catalysts toward various applications.
