Highly sensitive SERS analysis of the cyclic Arg-Gly-Asp peptide ligands of cells using nanogap antennas

Olivier Martin, Christian Santschi, Alejandro Ernesto Portela Otano

The cyclic RGD (cRGD) peptide ligands of cells have become widely used for treating several cancers. We report a highly sensitive analysis of c(RGDfC) using surface enhanced Raman spectroscopy (SERS) using single dimer nanogap antennas in aqueous environme ...

Improving the binding affinity of in-vitro-evolved cyclic peptides by inserting atoms into the macrocycle backbone

Christian Heinis, Jonas Alfred Karl Wilbs, Simon Jan Middendorp

Cyclic peptides binding to targets of interest can be generated efficiently with powerful in vitro display techniques, such as phage display or mRNA display. The cyclic peptide libraries screened with these methods are generated by altering in a combinator ...

Middle-down approaches for mass spectrometry-based protein identification and characterization

Kristina Srzentic

Mass spectrometry (MS) has emerged over the last two decades as the analytical technique of choice in systems-level protein studies, known as proteomics. Two are the MS-based approaches generally applied to proteomics: bottom-up (BU), which relies on the p ...

Gold-catalyzed direct alkynylation of tryptophan in peptides using TIPS-EBX

Jérôme Waser, Jonathan Brand, Gergely Laszlo Tolnai

The selective functionalization of peptides containing only natural amino acids is important for the modification of biomolecules. In particular, the installation of an alkyne as a useful handle for bioconjugation is highly attractive, but the use of a car ...

Aqueous Titanium Trichloride Promoted Reductive Cyclization of o-Nitrostyrenes to Indoles: Development and Application to the Synthesis of Rizatriptan and Aspidospermidine

Qian Wang, Jieping Zhu, Shuo Tong, Zhengren Xu, Mathias Mamboury

Treatment of o-nitrostyrenes with aqueous TiCl3 solution at room temperature afforded indoles via a formal reductive C(sp2)-H amination process. A range of functions such as halides (Cl, Br), carbonyl (ester, carbamate), cyano, hydroxyl and amino groups we ...

Improving binding affinity and stability of peptide ligands by substituting glycines with D-amino acids

Christian Heinis, Petr Leiman, David Gfeller, Shiyu Chen, Sergii Buth, Olivier Michielin

Improving the binding affinity and/or stability of peptide ligands often requires testing of large numbers of variants to identify beneficial mutations. Herein we propose a type of mutation that promises a high success rate. In a bicyclic peptide inhibitor ...
