Nitriles used to be known as cyanides; the smallest organic nitrile is ethanenitrile, CH3CN, (old name: methyl cyanide or acetonitrile – and sometimes now called ethanonitrile). 20099-89-2, formula is C9H6BrNO, Name is 4-(2-Bromoacetyl)benzonitrile. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves. Category: nitriles-buliding-blocks.
Choi, Sang-Kee;Lee, Youngjun;Yoon, Sang Eun;Choi, Hongseo;Kim, Jonghoon;Kim, Jong H.;Lee, Sanghee;Kim, Wook;Kim, Eunha research published 《 A tetrazine-fused aggregation induced emission luminogen for bioorthogonal fluorogenic bioprobe》, the research content is summarized as follows. Bioorthogonal fluorogenic probes allow spatiotemporally controlled mol. bioimaging with minimal perturbation of the native cellular environment. Due to favorable kinetics and reaction specificity in a physiol. environment, inverse electron-demand Diels – Alder reaction (iEDDA) for bioorthogonal fluorogenic bioimaging has gained immense attention in scientific field; however, the technique still needs to washout excess trans-cyclooctene labels, thereby reducing the robustness and exptl. convenience. In the present study, we report tetrazine-modified aggregation-induced emission luminogens for bioorthogonal fluorogenic bioimaging. We found that a unique mol. design strategy allowed incorporation of tetrazine on aggregation-induced emission luminogens with excellent fluorogenic properties. Moreover, tetrazine modification of aggregation-induced emission luminogens results in non-radiative decay, which induces fluorescence quenching. The systematic tunability of the emission wavelength of the fluorescent core skeleton allowed successful development of three different colorful fluorogenic tetrazine-fluorophores. Furthermore, an aggregate formation study and computational calculations revealed a synergistic fluorescent quenching effect between intramol. charge transfer and tetrazine-mediated non-radiative decay. The final simple conjugation between triphenylphosphonium and tetrazine-fluorophore enabled successful development of fluorogenic probes for spatiotemporally controlled bioorthogonal bioimaging of mitochondria in live cells with the iEDDA without washing the trans-cyclooctene label and tetrazine-fluorophore.
