A. J.;de Boer, Jan;Alexander, Morgan R. research published 《 Discovery of synergistic material-topography combinations to achieve immunomodulatory osteoinductive biomaterials using a novel in vitro screening method: The ChemoTopoChip》, the research content is summarized as follows. Human mesenchymal stem cells (hMSCs) are widely represented in regenerative medicine clin. strategies due to their compatibility with autologous implantation. Effective bone regeneration involves crosstalk between macrophages and hMSCs, with macrophages playing a key role in the recruitment and differentiation of hMSCs. However, engineered biomaterials able to simultaneously direct hMSC fate and modulate macrophage phenotype have not yet been identified. A novel combinatorial chem.-topog. screening platform, the ChemoTopoChip, is used here to identify materials suitable for bone regeneration by screening 1008 combinations in each experiment for human immortalized mesenchymal stem cell (hiMSCs) and human macrophage response. The osteoinduction achieved in hiMSCs cultured on the “hit” materials in basal media is comparable to that seen when cells are cultured in osteogenic media, illustrating that these materials offer a materials-induced alternative to osteo-inductive supplements in bone-regeneration. Some of these same chem.-microtopog. combinations also exhibit immunomodulatory stimuli, polarizing macrophages towards a pro-healing phenotype. Maximum control of cell response is achieved when both chem. and topog. are recruited to instruct the required cell phenotype, combining synergistically. The large combinatorial library allows us for the first time to probe the relative cell-instructive roles of microtopog. and material chem. which we find to provide similar ranges of cell modulation for both cues. Machine learning is used to generate structure-activity relationships that identify key chem. and topog. features enhancing the response of both cell types, providing a basis for a better understanding of cell response to micro topog. patterned polymers.

Britton, Luke;Skrodzki, Maciej;Nichol, Gary S.;Dominey, Andrew P.;Pawluc, Piotr;Docherty, Jamie H.;Thomas, Stephen P. research published 《 Manganese-Catalyzed C(sp²)-H Borylation of Furan and Thiophene Derivatives》, the research content is summarized as follows. Aryl boronic esters are bench-stable, platform building-blocks that can be accessed through metal-catalyzed aryl C(sp²)-H borylation reactions. C(sp²)-H bond functionalization reactions using rare- and precious-metal catalysts are well established, and while examples using Earth-abundant alternatives have emerged, Mn catalysis remains lacking. The Mn-catalyzed C-H borylation of furan and thiophene derivatives is reported alongside an in situ activation method providing facile access to the active Mn hydride species. Mechanistic studies showed that blue light irradiation directly affected catalysis by action at the metal center, that C(sp²)-H bond borylation occurs through a C-H metalation pathway, and that the reversible coordination of pinacolborane to the catalyst gave a Mn borohydride complex, which was as an off-cycle resting state.

Application In Synthesis of 611-13-2, Methyl 2-furoate has been identified as one of the volatile flavor compounds in tequila, okra, berrycactus and black currant juice.
Methyl 2-furoate, also known as fema 2703 or methyl pyromucate, belongs to the class of organic compounds known as furoic acid esters. These are ester derivatives of furoic acid.

Breton, Gary W.;Hahn, Lauren A.;Martin, Kenneth L. research published 《 Structural verification of a tetrahydrotetrazole compound》, the research content is summarized as follows. Tetrahydrotetrazoles are five-membered-ring heterocycles containing four contiguous saturated nitrogen atoms. Very few examples of such compounds have been reported in the literature. Our previous attempt at the synthesis of a member of this class of compound suggested that the N-N bonds may be more labile than expected. This finding raised the question as to whether the structures of any of the previously reported tetrahydrotetrazoles had been properly assigned. We have reproduced the synthesis of a reported tetrahydrotetrazole, namely 1,2-di-tert-Bu 3-phenyl-1H,2H,3H,10bH-[1,2,3,4]tetrazolo[5,1-a]isoquinoline-1,2-dicarboxylate, C₂₅H₃₀N₄O₄, and have now confidently confirmed its structure via X-ray crystallog. However, while sufficiently stable in the crystal phase, we discovered that it remains very labile in solution (having a half-life of only 15 min at 20°C in CDCl₃). A tentative reaction pathway for its dissociation based on ¹H NMR spectral evidence is provided.

Booth, Joshua R.;Davies, Joshua D.;Bon, Stefan A. F. research published 《 ω-Unsaturated methacrylate macromonomers as reactive polymeric stabilizers in mini-emulsion polymerization》, the research content is summarized as follows. Polymer latexes of poly(benzyl methacrylate) P(BzMA) were synthesized by mini-emulsion polymerization, using hexadecane as the hydrophobe and ω-unsaturated methacrylate-based macromonomers as a reactive stabilizer. The amphiphilic macromonomers were synthesized by catalytic chain transfer emulsion polymerization (CCTP) and subsequent chain extension via sulfur-free reversible addition-fragmentation chain transfer (SF-RAFT). Their critical micelle concentration (CMC) was determined by dynamic light scattering (DLS), and micelle size was measured using DLS and small angle X-ray scattering (SAXS). The surface activity of the stabilizers was measured by pendant drop tensiometry and compared to modelled behavior. For the mini-emulsion polymerizations, macromonomer stabilizers were added at a range of concentrations, with respect to the dispersed phase. Using less than 5 wt% stabilizer, SEM micrographs showed many of the particles were bowl-shaped. At concentrations of 5 wt% and higher, bimodal droplet and particle distributions were observed by DLS and SEM. We propose shear-dependent depletion flocculation as the explanation. The effectiveness of the reactive stabilizers was tested in terms of latex stability and mol. weight control. Resistance to coagulation during freeze-thaw cycles and prolonged dialysis were tested. Examination of P(BzMA) reaction kinetics and mol. weight indicated that the incorporation of macromonomer is gradual and less than quant. at the end of the polymerization process, in agreement with the mechanistic understanding.

The reagent di-tert-Bu ethynylimidodicarbonate is demonstrated as a β-aminoethyl anion synthetic equivalent It can be used to install ethyleneamine groups by exploiting its terminal alkyne reactivity with common organic electrophiles. Reactions exemplified with this terminal ynimide reagent include additions to imines, aldehydes, ketones, pyridinium salts, Michael acceptors, epoxides, as well as Pd-catalyzed Sonogashira couplings. Subsequent regioselective [3+2] cycloadditions of the alkynyl-imides (ynimides) generate N,N-di-Boc imide functionalized triazole and isoxazole heterocycles. Reduction of the ynimides with Pd-catalyzed hydrogenation generates ethyleneimides with easily removable N,N-di-Boc-carbamate protecting groups allowing for a flexible ynimide based approach to ethyleneamine installation.
