WebJun 22, 2024 · Abstract. The formation of oximes and hydrazones is employed in numerous scientific fields as a simple and versatile conjugation strategy. This imine-forming … WebJun 19, 2024 · The results showed that, in aqueous solution, the imine of the aliphatic amine was not stable, but oxime and hydrazone formed well in a pH dependent way. On the other hand, in organic solvents, the kinetic product was the imine derived from an aliphatic amine and the thermodynamic products were oxime and hydrazone.

WebOur data show that catalytic amine buffers can provide a simple and low-toxicity strategy for speeding hydrazone and oxime conjugations. We show that reaction rate constants of ca. 20–30 M−1 s−1 can be achieved even at pH 7 and above, with rate enhancements of up to 400-fold possible. WebThe oxime ligation with peptides and proteins is typically carried out over several hours in aqueous media at pH 4–5 with either aniline or p -phenylenediamine (pPDA) as catalysts (μM reactants, 10 mM catalysts). 1,37,38 While these ligation times are acceptable for the majority of applications, they are too slow for radiochemistry applications …
