Rotenoids from the Roots of Vicia faba L. (Fabaceae): Structural Characterization, Cytotoxic Effects, and Molecular Docking

Chemistry &Biodiversity, EarlyView.
ABSTRACT The chemical study of the ethanolic extract from the roots of Vicia faba led to the isolation of two isoflavonoids, alfalone and 8‐O‐methylretusine, as well as a mixture of rotenoids, including clitoriacetal and clitoriacetal B, the latter of which is reported for the first time.

A Tailored Phospho‐p53 Library Probes Antibody Specificity and Recognition Limitations

ChemBioChem, EarlyView.
Site‐specifically phosphorylated isoforms of the tumor suppressor p53 – encompassing all seven known phosphorylation sites within the TAD1 domain –are created upon optimization of semisynthesis protocols. This “designer" p53 library enabled validation of phosphorylation‐specific p53 antibodies and revealed epitope masking by phosphorylation in commonly

Internal Ubiquitin Electrophiles for Covalent Trapping and Inhibition of Deubiquitinases

ChemBioChem, Accepted Article.
The ubiquitin (Ub) system governs vital cellular processes in eukaryotic biology through an intricate network of Ub‐protein interactions. While semisynthetic C‐terminal Ub electrophiles (UbEs) are widely used to study Ub transfer and deubiquitinase (Dub) activity, they are limited to probing the active site while leaving other functionally important ...

A De Novo Designed Metalloprotein Displays Variable Thermal Stability and Binding Stoichiometry with Transition Metal Ions

ChemBioChem, EarlyView.
A de novo designed single‐chain coiled coil protein is unfolded in apo‐state but folds up upon addition of divalent transition metal ions Co(II), Ni(II), Cu(II), and Zn(II). The resulting metal‐bound complexes exhibit distinct thermal stability and metal stoichiometry, making this protein a promising starting point for the design of fully metal ...
