Bukowska, Agnieszka;Bester, Karol;Pytel, Maciej;Bukowski, Wiktor research published 《 Polymer Beads Decorated with Dendritic Systems as Supports for A³ Coupling Catalysts》, the research content is summarized as follows. The gel type microscopic polymer beads bearing epoxy functionalities were modified using the two-stage procedures in order to decorate their surface with the moieties of the zeroth order PAMAM type dendrimer and different heterocyclic aldehydes (2-pyridinecarboxaldehyde, 2-pyrrolidinecarboxaldehyde, furfural or 2-thiophenecarboxaldehyde). The polymeric supports provided in this manner were then used for the immobilization of copper(II) ions. The resulting materials were characterized using different instrumental techniques (optical microscopy, SEM, FTIR microscopy, DR UV-Vis, ICP-OES, and thermal anal.). They were also used as catalysts in the model A³ coupling reaction of benzaldehyde, morpholine and phenylacetylene. The best catalytic activity was found for the polymeric catalyst bearing 2-pyridinecarboxaldehyde moieties. It turned out to be effective in the A³ coupling reactions included different benzaldehyde, alkyne, and secondary amine derivatives, as well. It could also be recycled several times without a significant decrease in its activity in the model A³ coupling reaction.

Buchsteiner, Michael;Martinez-Rodriguez, Luis;Jerabek, Paul;Pozo, Iago;Patzer, Michael;Noethling, Nils;Lehmann, Christian W.;Fuerstner, Alois research published 《 Catalytic Asymmetric Fluorination of Copper Carbene Complexes: Preparative Advances and a Mechanistic Rationale》, the research content is summarized as follows. The Cu-catalyzed reaction of substituted α-diazoesters with fluoride gives α-fluoroesters with ee values of up to 95%, provided that chiral indane-derived bis(oxazoline) ligands were used that carry bulky benzyl substituents at the bridge and moderately bulky iso-Pr groups on their core. The apparently homogeneous solution of CsF in C₆F₆/hexafluoroisopropanol (HFIP) is the best reaction medium, but CsF in the biphasic mixture CH₂Cl₂/HFIP also provides good results. DFT studies suggest that fluoride initially attacks the Cu- rather than the C-atom of the transient donor/acceptor carbene intermediate. This unusual step is followed by 1,2-fluoride shift; for this migratory insertion to occur, the carbene must rotate about the Cu-C bond to ensure orbital overlap. The directionality of this rotatory movement within the C₂-sym. binding site determines the sense of induction. This model is in excellent accord with the absolute configuration of the resulting product as determined by x-ray diffraction using single crystals of this a priori wax-like material grown by capillary crystallization

Carbapenems are vital antibiotics, but their efficacy is increasingly compromised by metallo-β-lactamases (MBLs). Here we report the discovery and optimization of potent broad-spectrum MBL inhibitors. A high-throughput screen for NDM-1 inhibitors identified indole-2-carboxylates (InCs) as potential β-lactamase stable β-lactam mimics. Subsequent structure-activity relationship studies revealed InCs as a new class of potent MBL inhibitor, active against all MBL classes of major clin. relevance. Crystallog. studies revealed a binding mode of the InCs to MBLs that, in some regards, mimics that predicted for intact carbapenems, including with respect to maintenance of the Zn(II)-bound hydroxyl, and in other regards mimics binding observed in MBL-carbapenem product complexes. InCs restore carbapenem activity against multiple drug-resistant Gram-neg. bacteria and have a low frequency of resistance. InCs also have a good in vivo safety profile, and when combined with meropenem show a strong in vivo efficacy in peritonitis and thigh mouse infection models. [graphic not available: see fulltext]

Bourbon, Paul;Appert, Emeline;Martin-Mingot, Agnes;Michelet, Bastien;Thibaudeau, Sebastien research published 《 Complementary Site-Selective Sulfonylation of Aromatic Amines by Superacid Activation》, the research content is summarized as follows. Under superacidic conditions, aniline and indole derivatives such as p-methylacetanilide, 2-chloroacetanilide, oxindole, 2-methylindole, etc. are sulfonylated at low temperature with easy-to-access arenesulfonic acids or arenesulfonyl hydrazides ArS(O)₂Y (Ar = Ph, 4-fluorophenyl, naphthalen-2-yl, etc.; Y = OH, NHNH₂). By modification of the functional-group directing effect through protonation, this method allows nonclassical site functionalization by overcoming the innate regioselectivity of electrophilic aromatic substitution. This superacid-mediated sulfonylation of arenes RS(O)₂Ar [R = 5-acetamido-2-methylbenzen-1-yl, 2,3,4,9-tetrahydro-1H-carbazol-7-yl, 4-[(2S)-2-acetamido-3-methoxy-3-oxopropyl]benzen-1-yl, etc.] is complementary to existing methods and can be applied, through protection by protonation, to the late-stage site-selective functionalization of natural alkaloids I and active pharmaceutical ingredients.

Borkar, Maheshkumar R.;Martis, Elvis A. F.;Nandan, Santosh;Patil, Rajendra H.;Shelar, Amruta;Iyer, Krishna R.;Raikuvar, Kavita;Desle, Deepali;Coutinho, Evans C. research published 《 Identification of potential antileishmanial 1,3-disubstituted-4-hydroxy-6-methylpyridin-2(1H)-ones, in vitro metabolic stability, cytotoxicity and molecular modeling studies》, the research content is summarized as follows. The synthesis and in vitro evaluation of 1,3-disubstituted-4-hydroxy-6-methylpyridin-2(1H)-one derivatives I (R¹ = Pr, Bn, cyclopropyl, etc.; R² = H, Me, Br, OMe) against Leishmania donovani is reported. Amongst the compound library synthesized, mols. few compounds demonstrated substantial dose-dependent killing of the promastigotes. Their IC₅₀ values range from 55.0 to 77.0μg/mL, with I (R¹ = 4-FC₆H₄CH₂; R² = H) (IC₅₀ 55.75μg/mL) being equipotent with amphotericin B (IC₅₀ 50.0μg/mL, used as standard) and this most stable compound is metabolically stable in rat liver microsomes. Furthermore, the mols. are highly specific against leishmania as shown by their weak antibacterial and antifungal activity. In vitro cytotoxicity studies show the compounds lack any cytotoxicity. Furthermore, mol. modeling studies show plausibility of binding to Leishmania donovani topoisomerase 1 (LdTop1). Structure activity relationships reveal bulky substitutions on the pyridone nitrogen are well-tolerated, and such compounds have better binding affinity. Intramol. hydrogen bonds confer some rigidity to the mols., rendering a degree of planarity akin to topotecan. Taken together, the emphasis on the merits of mols. possessing the 1,3-disubstituted-4-hydroxy-6-methylpyridin-2(1H)-one skeleton as potential antileishmanial agents warranting further investigation.

Bolitho, Elizabeth M.;Coverdale, James P. C.;Bridgewater, Hannah E.;Clarkson, Guy J.;Quinn, Paul D.;Sanchez-Cano, Carlos;Sadler, Peter J. research published 《 Tracking Reactions of Asymmetric Organo-Osmium Transfer Hydrogenation Catalysts in Cancer Cells》, the research content is summarized as follows. Most metallodrugs are prodrugs that can undergo ligand exchange and redox reactions in biol. media. Here we have investigated the cellular stability of the anticancer complex [OsII[(η6-p-cymene)(RR/SS-MePh-DPEN)] [1] (MePh-DPEN=tosyl-diphenylethylenediamine) which catalyzes the enantioselective reduction of pyruvate to lactate in cells. The introduction of a bromide tag at an unreactive site on a Ph substituent of Ph-DPEN allowed us to probe the fate of this ligand and Os in human cancer cells by a combination of X-ray fluorescence (XRF) elemental mapping and inductively coupled plasma-mass spectrometry (ICP-MS). The BrPh-DPEN ligand is readily displaced by reaction with endogenous thiols and translocated to the nucleus, whereas the Os fragment is exported from the cells. These data explain why the efficiency of catalysis is low, and suggests that it could be optimized by developing thiol resistant analogs. Moreover, this work also provides a new way for the delivery of ligands which are inactive when administered on their own.

Bohme, Matthias D.;Eder, Tobias;Rothel, Maike B.;Dutschke, Patrick D.;Wilm, Lukas F. B.;Hahn, F. Ekkehardt;Dielmann, Fabian research published 《 Synthesis of N-Heterocyclic Carbenes and Their Complexes by Chloronium Ion Abstraction from 2-Chloroazolium Salts Using Electron-Rich Phosphines》, the research content is summarized as follows. N-Heterocyclic carbenes (NHCs) are commonly prepared by deprotonation of azolium salts using strong anionic bases. This reaction is often unselective, yielding alkali metal NHC complexes or dimerized NHCs. Alternatively, free NHCs are obtained by the dechlorination of 2-chloroazolium salts using electron-rich phosphines. PPh₃, PCy₃, and PtBu₃ are unsuitable for Cl⁺ abstraction, while the sterically encumbered tris(1,3-tert-butylimidazolidin-2-ylidenamino)phosphine (1) selectively removes Cl⁺ from 2-chloroazolium salts. Since bulky 1 does not bind to metal complexes, it was used for the preparation of NHC complexes via in situ Cl⁺ abstraction from 2-chloroazolium salts. The dechlorination was employed for the site-selective monometalation with Ir^I, Ir^III, Rh^I, Rh^III, and Ru^II of a bis-NHC precursor composed of a 2-chlorobenzimidazolium and a 2-chlorobenzimidazole group, followed by the preparation of the heterobimetallic Ir^III/Pd^II complex [18](BF₄)₂ by a dechlorination/oxidative addition reaction sequence.

Blanchard, John W.;Ripka, Barbara;Suslick, Benjamin A.;Gelevski, Dario;Wu, Teng;Muennemann, Kerstin;Barskiy, Danila A.;Budker, Dmitry research published 《 Towards large-scale steady-state enhanced nuclear magnetization with in situ detection》, the research content is summarized as follows. Signal amplification by reversible exchange (SABRE) boosts NMR signals of various nuclei enabling new applications spanning from magnetic resonance imaging to anal. chem. and fundamental physics. SABRE is especially well positioned for continuous generation of enhanced magnetization on a large scale; however, several challenges need to be addressed for accomplishing this goal. Specifically, SABRE requires (i) a specialized catalyst capable of reversible H2 activation and (ii) phys. transfer of the sample from the point of magnetization generation to the point of detection (e.g., a high-field or a benchtop NMR [NMR] spectrometer). Moreover, (iii) continuous parahydrogen bubbling accelerates solvent (e.g., methanol) evaporation, thereby limiting the exptl. window to tens of minutes per sample. In this work, we demonstrate a strategy to rapidly generate the best-to-date precatalyst (a compound that is chem. modified in the course of the reaction to yield the catalyst) for SABRE, [Ir(IMes)(COD)Cl] (IMes = 1,3-bis-[2,4,6-trimethylphenyl]-imidazol-2-ylidene; COD = cyclooctadiene) via a highly accessible synthesis. Second, we measure hyperpolarized samples using a home-built zero-field NMR spectrometer and study the field dependence of hyperpolarization directly in the detection apparatus, eliminating the need to phys. move the sample during the experiment Finally, we prolong the measurement time and reduce evaporation by presaturating parahydrogen with the solvent vapor before bubbling into the sample. These advancements extend opportunities for exploring SABRE hyperpolarization by researchers from various fields and pave the way to producing large quantities of hyperpolarized material for long-lasting detection of SABRE-derived nuclear magnetization.
