Chemoselective Late-Stage Functionalization of Peptides via Photocatalytic C2-Alkylation of Tryptophan (2023)
Journal Article
Lee, J. C., Cuthbertson, J. D., & Mitchell, N. J. (2023). Chemoselective Late-Stage Functionalization of Peptides via Photocatalytic C2-Alkylation of Tryptophan. Organic Letters, 25(29), 5459-5464. https://doi.org/10.1021/acs.orglett.3c01795

Across eukaryotic proteomes, tryptophan is the least abundant of the 20 canonical amino acids, which makes it an ideal chemical handle for the late-stage functionalization of peptide and protein scaffolds with minimal production of undesired isoforms...

Application of a Synthetic Ferredoxin‐Inspired [4Fe4S]‐Peptide Maquette as the Redox Partner for an [FeFe]‐Hydrogenase (2023)
Journal Article
Bombana, A., Shanmugam, M., Collison, D., Kibler, A. J., Newton, G. N., Jäger, C. M., …Mitchell, N. J. (2023). Application of a Synthetic Ferredoxin‐Inspired [4Fe4S]‐Peptide Maquette as the Redox Partner for an [FeFe]‐Hydrogenase. ChemBioChem, 24(18), Article e202300250. https://doi.org/10.1002/cbic.202300250

‘Bacterial-type’ ferredoxins host a cubane [4Fe4S]2+/+ cluster that enables these proteins to mediate electron transfer and facilitate a broad range of biological processes. Peptide maquettes based on the conserved cluster-forming motif have previous...

Journal Article
Amin, S. S., Jones, K. D., Kibler, A. J., Damian, H. A., Cameron, J. M., Butler, K. S., …Newton, G. N. (2023). Diphosphoryl‐functionalized Polyoxometalates: Structurally and Electronically Tunable Hybrid Molecular Materials. Angewandte Chemie International Edition, 62(23), Article e202302446. https://doi.org/10.1002/anie.202302446

Herein, we report the synthesis and characterization of a new class of hybrid Wells–Dawson polyoxometalate (POM) containing a diphosphoryl group (P2O6X) of the general formula [P2W17O57(P2O6X)]6− (X=O, NH, or CR1R2). Modifying the bridging unit X was... Read More about Diphosphoryl‐functionalized Polyoxometalates: Structurally and Electronically Tunable Hybrid Molecular Materials.

Cysteine-Selective Modification of Peptides and Proteins via Desulfurative C−C Bond Formation (2023)
Journal Article
