Title: Towards click bioconjugations on cube-octameric silsesquioxane scaffolds. Author: Fabritz S, Heyl D, Bagutski V, Empting M, Rikowski E, Frauendorf H, Balog I, Fessner WD, Schneider JJ, Avrutina O, Kolmar H. Journal: Org Biomol Chem; 2010 May 07; 8(9):2212-8. PubMed ID: 20401398. Abstract: Cube-octameric silsesquioxane (POSS) based conjugation scaffolds for copper catalysed azide-alkyne [3+2] cycloaddition are reported. The synthetic route to octaazido and octaalkyno functionalised POSS templates without cage rearrangements is described. A set of click couplings is conducted including the first effective conjugation with a fully unprotected functional peptide towards a POSS assembled peptide octamer.[Abstract] [Full Text] [Related] [New Search]
