I am excited to share that our manuscript on vinyl phosphonamidates (VPAs) as latent electrophiles for cysteine targeting has just been published in the Journal of the American Chemical Society. doi.org/10.1021/jacs... Thanks to my great colleagues who help me shape this project!

Modular Vinyl Phosphonamidates for Cysteine-Directed Protein Targeting
Covalent inhibitors and chemical probes targeting ligandable cysteine residues have emerged as powerful tools for drug discovery and proteomics. In this study, we introduce vinyl phosphonamidates (VPA...

🎉 Excited to share the first bioRxiv & medRxiv preprint from my PostDoc. It’s been — and continues to be — an incredible journey into the world of epigenetics, exploring how we can reprogram oncogenic transcription factor activity using chemical inducers of proximity. 👨‍🔬🧪🧬🧫

Targeted Transcriptional Repression by Induced Proximity
Most cancer driving proteins remain undruggable due to the absence of ligandable pockets and their reliance on intrinsically disordered or protein-DNA/protein-protein interactions. Transcription facto...

Brace yourselves! Arif from the Fiedler lab discovered+characterized in collaboration with us & other groups within the @fmp-berlin.de a novel PTM: autocatalytic oligophosphorylation (up to 6 Phosphates 😲). Still mysterious in origin, function & regulation. www.nature.com/articles/s41...

Interesting talk by Mark de Geus at #Lunteren. He talked about his work on incorporating aryl thiols into proteins and exploring, if they can be labeled selectively over cysteine residues. Cool applications to site-selective protein labeling.

To my friends and colleagues at UAB, IU, UF, FSU, UL, WashU, OSU, CWRU, etc, etc. Call both your senators and your representative. They listen. Emphasize the direct economic impact of NIH research, and the indirect impacts on pharmaceutical/biotech. Underscore its relevance to national security.
