Polyhedral Oligomeric Silsesquioxane (POSS) Bearing Glyoxylic Aldehyde as Clickable Platform Towards Multivalent Conjugates

Chemistry. 2017 Dec 19;23(71):17867-17869. doi: 10.1002/chem.201703794. Epub 2017 Oct 4.

Abstract

The straightforward access to octafunctional "cubic" silsesquioxane platform grafter with pendant glyoxylic aldehydes is described. This clickable hybrid platform readily reacts with oxyamine or hydrazide compounds to provide, respectively, oxime and acylhydrazone conjugates, thereby offering a new and effective access from which one can elaborate multivalent systems for the targeting of biomolecules of interest.

Keywords: hydrazone; ligations; multivalent platform; oxyamine; silsesquioxane.
