Liposome surface functionalization based on different anchoring lipids via Staudinger ligation.
Liposome surface functionalization facilitates numerous potential applications of liposomes, such as enhanced stability, bioactive liposome conjugates, and targeted drug, gene and image agent delivery. Anchoring lipids are needed for grafting ligands of interest and play important roles in ligand grafting density, liposome stability, and liposome chemical and physical characteristics as well. I...
متن کاملProtein-liposome conjugates using cysteine-lipids and native chemical ligation.
Liposomes have become popular drug delivery vehicles and have more recently also been applied as contrast agents for molecular imaging. Most current methods for functionalization of liposomes with targeting proteins rely on reactions of amine or thiol groups at the protein exterior, which generally result in nonspecific conjugation at multiple sites on the protein. In this study, we present nat...
متن کاملSynthesis of coumarin or ferrocene labeled nucleosides via Staudinger ligation
BACKGROUND Reaction of azides with triaryl phosphines under mild conditions gives iminophosphoranes which can react with almost any kind of electrophilic reagent, e.g. aldehydes/ketones to form imines or esters to form amides. This so-called Staudinger ligation has been employed in a wide range of applications as a general tool for bioconjugation including specific labeling of nucleic acids. ...
متن کاملDNA conjugation by Staudinger ligation.
Two 5 modified 2'-deoxyuridin triphosphates and a 7 modified 2'-deoxy-7-deazaadenosine were synthesized carrying a terminal azide linked to the base. For probing the sterical influence on incorporation and Staudinger ligation different sized flexible linkers were chosen. All three nucleotides can completely replace their natural counterparts in primer extension as well as polymerase chain react...
متن کاملProtein Assembly Using the Staudinger Ligation
Introduction New methods are facilitating the total chemical synthesis of proteins. In particular, the chemical ligation of synthetic peptides provides a convergent route to proteins. Currently, the most common ligation method is “native chemical ligation” [1]. In native chemical ligation, the thiolate of an N-terminal cysteine residue of one peptide attacks the C-terminal thioester of a second...
