Convergent Assembly of Homo‐ and Heterotypic Ubiquitin Chains from Functionalized, Expressed Monomers via Thiol‐Ene Chemistry

open access: yesAngewandte Chemie International Edition, EarlyView.
Generating functionalized ubiquitin building blocks via expression in E. coli paves the way to different di‐, tri‐, and tetra‐ubiquitin chains. Light‐induced thiol‐ene click reactions, combined with a masking and protection strategy, are harnessed to establish controlled ubiquitin chain assembly and to allow the semisynthesis of site‐selectively ...

Building a Bridge Between Ambient MS and LC‐MS by Non‐Exhaustive Microdesorption

open access: yesAngewandte Chemie International Edition, Accepted Article.
Ambient mass spectrometry (AMS) offers rapid screening but faces challenges in analyzing complex samples due to high matrix effects and limited selectivity. The absence of a separation step can also lead to false positives due to the isomers or isobars.

Chemically Enhanced Immunogenicity of Bacteria by Supramolecular Functionalization with an Adjuvant

open access: yesChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Poorly immunogenic pathogens are a major cause of infectious disease. We chemically modified the surface of such a pathogen (Staphylococcus aureus) with a synthetic adjuvant to boost immunogenicity. “Adjuvanted” S. aureus induced improved immune responses in macrophages compared to unadulterated bacteria.

Annulated Radical Cations with a C4E2‐Core (E = P, As, Sb): Stable Pnictogen Analogs of Elusive Aryl Radical Anions of Birch Reduction Reactions

open access: yesAngewandte Chemie International Edition, Accepted Article.
The benzene radical anion (C6H6)●–, possessing a 7π‐electron count, is a crucial intermediate in the Birch reduction and has been extensively studied both experimentally and theoretically. Herein, we report the tricyclic pnictogen radical cations [(ADC)E]2[B], [2‐E][B] (ADC = PhC{N(Dipp)C}2; Dipp = 2,6‐iPr2C6H3; E = P, As, Sb; [B] = [B1] = B(C6F5)4 or [

Contentious Engagement: Understanding Protest Participation in Latin American Democracies

open access: yesJournal of Politics in Latin America, 2015
Why has protest participation seemingly exploded across much of Latin America in recent years? How do individual- and country-level characteristics interact to explain the rise of contentious politics in countries like Argentina, Brazil, and Venezuela? I
