Reductive Cleavage of Secondary Sulfonamides: Converting Terminal Functional Groups into Versatile Synthetic Handles.

open access: yesJournal of the American Chemical Society, 2019
Sulfonamides are pervasive in pharmaceuticals and agrochemicals, yet they are typically considered as terminal functional groups rather than synthetic handles.

Designing Enzymatic Reactivity with an Expanded Palette

open access: yesChemBioChem, EarlyView.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...

Synthesis and cytotoxic activities of novel copper and silver complexes of 1,3-diaryltriazene-substituted sulfonamides

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2019
In this study, a series of 10 novel copper (II) and silver complexes of 1,3-diaryltriazene-substituted sulfonamides was synthesised. All the synthesised ligands and their metal complexes were assessed for in vitro cytotoxicity against human colorectal ...

Catalysis in Chemical Modification of Proteins

open access: yesChemCatChem, EarlyView.
Catalytic principles of synthetic organic chemistry have been increasingly applied to chemical modification of proteins during the recent years. This review article describes how seven types of catalytic systems —electrocatalysis, photocatalysis, metal catalysis, acid catalysis, organocatalysis, supramolecular catalysis, and heterogeneous catalysis ...

KEAP1‐NRF2 protein–protein interaction inhibitors: Design, pharmacological properties and therapeutic potential

open access: yesMedicinal Research Reviews, Volume 43, Issue 1, Page 237-287, January 2023., 2023
Abstract The transcription factor nuclear factor erythroid 2‐related factor 2 (NRF2) is considered the master regulator of the phase II antioxidant response. It controls a plethora of cytoprotective genes related to oxidative stress, inflammation, and protein homeostasis, among other processes.
