Description Methoxy poly(ethylene glycol) 2-pyridyl KAT 5K (mPEG KAT 5K) is a monofunctional, methyl ether PEG featuring a terminal potassium acyltrifluoroborate for facile, rapid functionalization. Potassium acyltrifluoroborates (KATs) are stable functional groups that undergo rapid amide-forming ligations with hydroxylamines in aqueous media, in the presence of unprotected functional groups. In addition to its compatibility, these reactions proceed relatively quickly, lending to their use with sensitive biological reagents. This conjugation reaction offers a new approach to the synthesis of complex molecules without the complication of side reactions, such protein-polymer conjugates. KATs also undergo amide or imide-forming ligations in acidic conditions when reacted with primary amines or amides, respectively, as an alternative to classical acylation chemistry.
Application Activated PEG derivatives can be used to modify peptides, proteins, or in other bioconjugation applications. PEGylated materials have found broad use in drug delivery systems, virology, and immunology, as the incorporation of PEG improves pharmacological properties such as increased water solubility, enhanced resistance to degradation (protein hydrolysis), increased circulation half-life, and reduced antigenicity. In addition to PEGylation, activated PEG derivatives can also be used to form networks for tissue engineering or drug delivery applications, depending on the architecture and reactivity.
