Thioarylmaleimides: accessible, tunable, and strongly emissive building blocks

A series of thioarylmaleimides was synthesized to investigate how variation of the thioaryl group can be used to control absorption and emission properties in solution and in the solid-state. Fine-tuning of the photochemical properties was found to be possible using this strategy, and a rainbow of colours and emission wavelengths are accessible in a single step from commercially available compounds.

NATURAL PRODUCT SYNTHESIS VIA CYCLOADDITIONS WITH N-SULFINYL DIENOPHILES

Diels-Alder cycloadducts derived from N-sulfinyl dienophiles have been used for stereospecific preparation of acyclic unsaturated amines and in stereospecific syntheses of threo-sphingosine (31) and erythro sphingosine (32).Methodology based upon these cycloadducts is also currently being developed for total synthesis of the microbial metabolite staurosporine (46).

Organohalogens Naturally Biosynthesized in Marine Environments and Produced as Disinfection Byproducts Alter Sarco/Endoplasmic Reticulum Ca2+ Dynamics

Contemporary sources of organohalogens produced as disinfection byproducts (DBPs) are receiving considerable attention as emerging pollutants because of their abundance, persistence, and potential to structurally mimic natural organohalogens produced by bacteria that serve signaling or toxicological functions in marine environments. Here, we tested 34 organohalogens from anthropogenic and marine sources to identify compounds active toward ryanodine receptor (RyR1), known toxicological targets of non-dioxin-like polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs). [3H]Ryanodine ([3H]Ry) binding screening (?2 muM) identified 10 highly active organohalogens. Further analysis indicated that 2,3-dibromoindole (14), tetrabromopyrrole (31), and 2,3,5-tribromopyrrole (34) at 10 muM were the most efficacious at enhancing [3H]Ry binding. Interestingly, these congeners also inhibited microsomal sarcoplasmic/endoplasmic reticulum (SR/ER) Ca2+ ATPase (SERCA1a). Dual SERCA1a inhibition and RyR1 activation triggered Ca2+ efflux from microsomal vesicles with initial rates rank ordered 31 > 34 > 14. Hexabromobipyrroles (25) enhanced [3H]Ry binding moderately with strong SERCA1a inhibition, whereas pyrrole (24), 2,3,4-tribromopyrrole (26), and ethyl-4-bromopyrrole-2-carboxylate (27) were inactive. Of three PBDE derivatives of marine origin active in the [3H]Ry assay, 4?-hydroxy-2,3?,4,5?,6-pentabromodiphenyl ether (18) was also a highly potent SERCA1a inhibitor. Molecular targets of marine organohalogens that are also DBPs of emerging environmental concern are likely to contribute to their toxicity.

Large Changes in Fluorescent Color and Intensity of Symmetrically Substituted Arylmaleimides Caused by Subtle Structure Modifications

Herein we report on four diarylmaleimides based on 3- or 2-substituted benzothiophene (M3S or M2S) and benzofuran (M3O or M2O), which show very different emission properties: aggregation-caused quenching (ACQ), aggregation-induced emission (AIE), and dual-state strong emission (DSE) in both solution and solid states. Their emission color in the solid state can be adjusted from green?yellow into red. M2O displays strong red solid-state emission at 630 nm with a quantum yield of 46.3 %. Single-crystal X-ray diffraction analysis confirms that their large distinction in solid-state emission originates from their different packing structures: hydrogen-bonded organic frameworks (HOFs) for M3S, a staggered structure for M3O, J-aggregation for M2S, and weak H-aggregation for M2O. HOF of M3S and weak H-aggregation of M2O make them produce inverse-type piezochromic fluorescence: blueshifted ?turn-on? and redshifted ?turn-off? emission, respectively. These results provide new insight in fluorescence manipulated by subtle structure modification.

Homogeneous bispecifics by disulfide bridging

We report on a chemical platform to generate site-specific, homogeneous, antibody-antibody conjugates by targeting and bridging disulfide bonds. A bispecific antibody construct was produced in good yield through simple reduction and bridging of antibody fragment disulfide bonds, using a readily synthesized bis-dibromomaleimide cross-linker. Binding activity of antibodies was maintained, and in vitro binding of target antigens was observed. This technology is demonstrated through linking scFv and Fab antibody fragments, showing its potential for the construction of a diverse range of bispecifics.

P-chirogenic silylphosphine-boranes: Synthesis and phospha-Michael reactions

Chiral and achiral silylphosphine-boranes were prepared in high yields by reaction of phosphide boranes with halogenosilanes. Their reaction at room temperature with Michael acceptors afforded 1,4-addition products as silylenol ether or ketone derivatives in good to excellent yields. In the case of the 2,3-dihalogeno-maleimides, the double addition of silylphosphine-borane led to the corresponding trans-diphosphine-boranes in 86% yield. Noteworthy, the reaction of Pchirogenic silylphosphine-boranes with enones afforded the phospha-Michael adducts without racemization at the P-center. While the silylphosphine-boranes have been scarcely described so far, these compounds demonstrate their great interest for the synthesis of chiral and achiral functionalized organophosphorus compounds.

Polymorphism-dependent fluorescence of bisthienylmaleimide with different responses to mechanical crushing and grinding pressure

A herringbone structured compound, 3,4-bisthienylmaleimide (BTM), with reversible four-color and on/off switching upon external stimuli is reported here. Three kinds of BTM crystals with strong red (RC), orange (OC) and yellow (YC) fluorescence, as well as a brown solid (BS) with weak orange luminescence are obtained in the experiments. Heating, solvent vapor and pressure, including crushing and grinding, can reversibly switch BTM’s emission between RC, OC, YC and BS. Base vapor (NEt3)-heating cycle treatment of BTM film in polystyrene can induce emission switching between bright/dark (on/off) states. The results of crystal structural analysis and photophysical property studies demonstrate that although OC and YC have the same crystal structure, they exhibit different fluorescent properties, due to their different surface structures. Heat induces metastable RC, with orderly pi-stacking, to turn into stable OC or YC, with brick stone stacking. Crushing can damage the surface structure of OC and transform it into YC without altering the crystal structure. Grinding OC or YC destroys the orderly stacking to yield amorphous BS.

Inhibitors of Protein Kinase C. 1. 2,3-Bisarylmaleimides

The design and synthesis of a series of novel inhibitors of protein kinase C (PKC) is described.These 2,3-bisarylmaleimides were derived from the structural lead provided by the indolocarbazoles, staurosporine and K252a.Optimum activity required the imide NH, both carbonyl groups, and the olefinic bond of the maleimide ring. 2,3-Bisindolylmaleimides were the most active, and the potency of these was improved by a chloro substituent at the 5-position of one indole ring (compound 28, IC50 0.11 muM).In a series of (phenylindolyl)maleimides, nitro compound 74 was most active (IC50 0.67 muM).Naphthalene 19 and benzothiophene 21 showed greater than 100-fold selectivity for inhibition of PKC over the closely related cAMP-dependent protein kinase (PKA).

Bromo- and thiomaleimides as a new class of thiol-mediated fluorescence ‘turn-on’ reagents

Bromo- and thiomaleimides are shown to serve as highly effective quenchers of a covalently attached fluorophore. Reactions with thiols that lead to removal of the maleimide conjugation, or detachment of the fluorophore from the maleimide, result in ‘turn-on’ of the fluorescence. These reagents thus offer opportunities in thiol sensing and intracellular reporting. The Royal Society of Chemistry.
