Gonzalez-Lainez, Miguel;Jimenez, M. Victoria;Azpiroz, Ramon;Passarelli, Vincenzo;Modrego, F. Javier;Perez-Torrente, Jesus J. research published ã€?N-Methylation of Amines with Methanol Catalyzed by Iridium(I) Complexes Bearing an N,O-Functionalized NHC Ligandã€? the research content is summarized as follows. A set of neutral [IrBr(L₂)(κC-^tBuImCH₂PyCH₂OMe)] and cationic [Ir(L₂)(κ²C,N-^tBuImCH₂PyCH₂OMe)]PF₆ (L₂ = cod, (CO)₂) Ir(I) compounds featuring a flexible lutidine-derived polydentate ligand having NHC and -OMe as donor functions were evaluated as catalyst precursors for the N-methylation of aniline using MeOH both as a reducing agent and a C1 source. The carbonyl complexes are somewhat more active than the related diene compounds with the neutral compound [IrBr(CO)₂(κC-^tBuImCH₂PyCH₂OMe)] being the more active. A range of aromatic primary amines, including heterocyclic amines, were selectively transformed into the corresponding N-methylamino derivatives using this catalyst at a low catalyst loading (0.1 mol %) and substoichiometric amounts of Cs₂CO₃ (half equiv) as a base, in MeOH at 423 K. For aliphatic primary amines, selective N,N-dimethylation was achieved under the same catalytic conditions. The unselective deprotonation of the methylene linkers in [IrBr(CO)₂(κC-^tBuImCH₂PyCH₂OMe)] affords two isomeric neutral complexes featuring a coordinated dearomatized pyridine core, which were converted into [Ir(OMe)(CO)₂(κC-^tBuImCH₂PyCH₂OMe)] upon addition of MeOH. This compound undergoes thermal activation of a C-H bond of the tert-Bu group to give the cyclometalated Ir(I) complex [Ir(CO)₂{κ²C,C-(-CH₂Me₂C-ImCH₂PyCH₂OMe)}] featuring a bidentate C,C-coordinated NHC ligand. Mechanistic studies support a borrowing H mechanism proceeding through Ir(I) intermediates with the methoxo complex as the catalytic active species and the cyclometalated complex as the catalyst resting state. D labeling experiments demonstrated that both species are in equilibrium under catalytic conditions, which is consistent with the exhibited catalytic activity of the cyclometalated complex.

Garcia de Jalon, Elvira;Ruiz de Garibay, Gorka;Haug, Bengt Erik;McCormack, Emmet research published ã€?CytoCy5S, a compound of many structures. in vitro and in vivo evaluation of four near-infrared fluorescent substrates of nitroreductase (NTR)ã€? the research content is summarized as follows. CytoCy5S, a quenched, red-shifted fluorescent probe, has been used to exploit the imaging potential of the nitroreductase (NTR) reporter gene platform. Its use has been reported in a number of publications, however there are discrepancies in both the reported structure and its physicochem. properties. Herein, we aim to highlight these discrepancies and to define the best candidate of the four substrates under study for preclin. work in NTR reporting by optical applications. We report the synthesis, purification and characterization of four NTR substrates, including alternately described structures currently referred by the name CytoCy5S. A comparative NTR enzymic assay was performed to assess the spectroscopic characteristics of the different reductively activated probes. The NTR expressing triple-neg. breast carcinoma cell line, MDA-MB-231 NTR⁺, was employed to compare, both in vitro and in vivo, the suitability of these fluorescent probes as reporters of NTR activity. Comparison of the reporting properties was achieved by flow cytometry, fluorescence microscopy and optical imaging, both in vivo and ex vivo. This study evaluated the different spectroscopic and biol. characteristics of the four substrates and concluded that substrate 1 presents the best features for oncol. in vivo preclin. optical imaging.

Ge, Yuxi;Huang, Bin research published ã€?Light-emitting analogues based on triphenylamine modified quinoxaline and pyridine[2,3-b]pyrazine exhibiting different mechanochromic luminescenceã€? the research content is summarized as follows. A series of light-emitting analogs, [4-(2,3-diphenyl-quinoxalin-6-yl)-phenyl]-diphenyl-amine (TPA-DPQ) and [4-(2,3-diphenyl-pyrido[2,3-b]pyrazin-7-yl)-phenyl]-diphenyl-amine (TPA-DPP) are synthesized and characterized. TPA-DPQ and TPA-DPP possess similar donor-acceptor structures, in which triphenylamine is used as an electron donor while 2,3-diphenyl-quinoxaline (DPQ) and its analog 2,3-diphenyl-pyridine[2,3-b]pyrazine (DPP) serve as electron acceptors. Due to the stronger electron-withdrawing ability of DPP compared with DPQ, TPA-DPP exhibits longer but weaker emission than TPA-DPQ as expected. However, TPA-DPQ and TPA-DPP show different mechanochromic luminescence (MCL) properties with emission color changes of 42 and 10 nm, resp. Crystallog. anal. demonstrates that changes of CH···π and CH···N intermol. interactions are responsible for the significantly different MCL behaviors of the two compounds This work will provide some guidance for the rational design of MCL-active fluorophores.

Georgiou, Panagiotis G.;Marton, Huba L.;Baker, Alexander N.;Congdon, Thomas R.;Whale, Thomas F.;Gibson, Matthew I. research published ã€?Polymer Self-Assembly Induced Enhancement of Ice Recrystallization Inhibitionã€? the research content is summarized as follows. Ice binding proteins modulate ice nucleation/growth and have huge (bio)technol. potential. There are few synthetic materials that reproduce their function, and rational design is challenging due to the outstanding questions about the mechanisms of ice binding, including whether ice binding is essential to reproduce all their macroscopic properties. Here we report that nanoparticles obtained by polymerization-induced self-assembly (PISA) inhibit ice recrystallization (IRI) despite their constituent polymers having no apparent activity. Poly(ethylene glycol), poly(dimethylacrylamide), and poly(vinylpyrrolidone) coronas were all IRI-active when assembled into nanoparticles. Different core-forming blocks were also screened, revealing the core chem. had no effect. These observations show ice binding domains are not essential for macroscopic IRI activity and suggest that the size, and crowding, of polymers may increase the IRI activity of “non-active” polymers. Poly(vinylpyrrolidone) particles had ice crystal shaping activity, indicating this polymer can engage ice crystal surfaces, even though on its own it does not show any appreciable ice recrystallization inhibition. Larger (vesicle) nanoparticles are shown to have higher ice recrystallization inhibition activity compared to smaller (sphere) particles, whereas ice nucleation activity was not found for any material. This shows that assembly into larger structures can increase IRI activity and that increasing the “size” of an IRI does not always lead to ice nucleation. This nanoparticle approach offers a platform toward ice-controlling soft materials and insight into how IRI activity scales with mol. size of additives.

Gerth, Marieke;Berrocal, Jose Augusto;Bochicchio, Davide;Pavan, Giovanni M.;Voets, Ilja K. research published ã€?Discordant Supramolecular Fibres Reversibly Depolymerised by Temperature and Lightã€? the research content is summarized as follows. Synthetic stimuli responsive supramol. polymers attract increasing interest for their ability to mimic the unique properties of natural assemblies. Here we focus on the well-studied benzene-1,3,5-tricarboxamide (BTA) motif, and substitute it with two (S)-3,7-dimethyloctyl groups and an azobenzene photoswitch. We demonstrate the UV (λ=365 nm) induced depolymerization of the helical hydrogen-bonded polymers in methylcyclohexane (MCH) through CD and UV-vis spectroscopy in dilute solution (15μM), and NMR and iPAINT super-resolution microscopy in concentrated solution (300μM). The superstructure can be regenerated after thermal depolymerization, while repeated depolymerization can be reversed without degradation by irradiating at λ=455 nm. Mol. dynamics simulations show that the most energetically favorable configuration for these polymers in MCH is a left-handed helical network of hydrogen-bonds between the BTA cores surrounded by two right-handed helixes of azobenzenes. The responsiveness to two orthogonal triggers across a broad concentration range holds promise for use in, for example, photo-responsive gelation.
