The tetrazine/trans-cyclooctene ligation stands out {from the|in the} bioorthogonal toolbox {due to|because of|as a result of|on account of|resulting from|as a consequence of} its exceptional reaction kinetics, enabling {multiple|numerous|several|a number of|many|various} molecular technologies in vitro and in living systems. {Highly|Extremely|Very|Hugely} reactive 2-pyridyl-substituted tetrazines have {become|turn out to be|grow to be|turn into|develop into|come to be} state-of-the-art for time-critical processes and selective reactions at {very|extremely|really|quite|incredibly|pretty} low concentration. {It is|It’s|It really is|It truly is|It can be|It is actually} {widely|extensively|broadly} accepted that the enhanced reactivity {of these|of those} chemical tools is attributed {to the|towards the|for the} electron-withdrawing {effect|impact} {of the|from the|in the|on the|with the|of your} heteroaryl substituent. In contrast, we show that observed reaction {rates|prices} are way {too|as well|also} {high|higher} {to be|to become} explained on this basis. Computational investigation of this phenomenon revealed that distortion {of the|from the|in the|on the|with the|of your} tetrazine {caused|brought on|triggered} by intramolecular N-N repulsion plays a {key|important|crucial|essential} {role|function|part} in accelerating the cycloaddition step. {While|Whilst|Although|Even though|When|Though} we show that the {limited|restricted} stability of tetrazines {under|below|beneath} physiological {conditions|circumstances|situations} strongly correlates {with the|using the|with all the|together with the} electron-withdrawing {effect|impact} {of the|from the|in the|on the|with the|of your} substituent, intramolecular destabilization increases the reactivity {without|with out|without having|with no|devoid of|without the need of} {reducing|decreasing|lowering|minimizing} stability. Guided by these {fundamental|basic} insights we demonstrate application {in the|within the|inside the} {design|style|design and style} of {highly|extremely|very|hugely} reactive tetrazines with superior stability, {finally|lastly|ultimately} evading the reactivity/stability trade-off for bioorthogonal tetrazine tools.
