Graphene quantum dots decorated with maleimide and zinc tetramaleimido-phthalocyanine: Application in the design of ?OFF-ON? fluorescence sensors for biothiols

The fabrication of maleimide-derivatized graphene quantum dots (M-GQDs) and zinc phthalocyanine (2) as novel sensor probes for the selective detection of biothiols (cysteine, homocysteine or glutathione) through the rapid and specific Michael addition reaction between biothiols and the maleimide-derivatized probes is presented in this study. GQDs directly functionalized with maleimide units (M-GQDs) were synthesized and deployed for biothiols recognition following the principle of Michael addition. M-GQDs probe was found to be highly sensitive and selective towards biothiols detection in the nanomolar range in aqueous solution and at physiological pH (7.0). On the other hand, non-covalent interaction between pristine GQDs and novel zinc tetramaleimido-derivatized phthalocyanine resulted in the quenching of the pristine GQDs fluorescence emission which was switched back to the ?ON? mode by Michael addition mechanism in the presence of biothiols. Tested relevant biomolecules did not interfere in the quantitative recognition of the biothiols. The probes showed to be highly sensitive, specific and selective for biothiols sensing in simulated real samples.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. 1122-10-7. Introducing a new discovery about 1122-10-7, Name is 3,4-Dibromo-1H-pyrrole-2,5-dione

Synthesis of 6H-pyrrolo[3?,4?:2,3][1,4]diazepino[6,7,1-hi]indole-8,10(7H,9H)-dion es using 3-bromo-4-(indol-1-yl)maleimide scaffold

Series of 3-arylalkyl- or 3-alkylamino-4-(indol-l-yl)maleimides and bis(indol-l-yl)maleimides were synthesised. The cyclization of the 3-substituted 4-(indol-l-yl)maleimides under the action of acids resulted in the formation of diazepine[1,4] derivatives with indoline and maleimide nuclei annelated. These compounds readily produced the corresponding indolomaleimidodiazepines[1,4] after dehydrogenation.

Synthesis and characterisation of peripherally functionalised dendritic molecules

A number of peripherally functionalised dendritic molecules were synthesised in almost quantitative yield by a synthetic method involving the reaction between amines and isocyanates. The peripheral functional groups were incorporated by preparing a number of branched subunits, based on tris(hydroxymethyl)aminomethane (TRIS), 1, possessing three nitro, methoxy, methyl or maleimide terminal functionalities. Attachment of these branched units to the core molecules 4,4?-methylenebis(phenyl isocyanate) 13 and 1,3,5-benzene triisocyanate 20 afforded the corresponding dendritic molecules possessing 6 or 9 peripheral functional groups. Functional group conversions on the dendritic molecules have been successfully carried out, including hydrogenation of the terminal nitro to the corresponding amine and cleavage of the methoxy ether to give the corresponding phenol.

New functional handle for use as a self-reporting contrast and delivery agent in nanomedicine

The synthesis and photophysical characterization of a chromophore-bridged block copolymer system is presented. This system is based on a dithiomaleimide (DTM) functional group as a highly emissive functionality which can readily be incorporated into polymeric scaffolds. A key advantage of this new reporter group is its versatile chemistry, ease of further functionalization, and notably small size, which allows for ready incorporation without affecting or disrupting the self-assembly process critical to the formation of core-shell polymeric contrast and drug delivery agents. We demonstrate the potential of this functionality with a diblock system which has been shown to be appropriate for micellization and, when in the micellar state, does not self-quench. The block copolymer is shown to be significantly more emissive than the lone dye, with a concentration-independent emission and anisotropy profile from 1.5 mM to 0.15 muM. An emission lifetime and anisotropy decay comparison of the block copolymer to its micelle displays that time-domain fluorescence lifetime imaging (FLIM) is able to rapidly resolve differences in the supramolecular state of this block-dye-block polymer system. Furthermore, the ability to resolve these differences in the supramolecular state means that the DTM micelles are capable of self-reporting when disassembly occurs, simply by monitoring with FLIM. We demonstrate the great potential for in vitro applications that this system provides by using FLIM to observe micelle disassembly in different vascular components of rat hippocampal tissue. In total this system represents a new class of in-chain emitter which is appropriate for application in quantitative imaging and the tracking of particle degradation/disassembly events in biological environments.
