Conditional Stabilization of the Hypoxia‐Inducible Factor HIF1α— Photoswitchable Stapled Peptides Prevent Elongin BC–Mediated Degradation

Angewandte Chemie, EarlyView.
Visible‐light photoswitchable peptides enable the stabilization of the hydroxylated hypoxia transcription factor 1α (HIF1α—OH) by targeting the pVHL‐EloBC interaction. Significant differences in conformation, binding, and transcription of HIF‐targeted genes between the photostationary states (PSS) were demonstrated.

Crystal structure and Hirshfeld surface analysis of 3-phenyl-1-{3-[(3-phenylquinoxalin-2-yl)oxy]propyl}-1,2-dihydroquinoxalin-2-one

Acta Crystallographica Section E: Crystallographic Communications
In the title compound, C31H24N4O2, the quinoxaline units are distinctly non-planar and twisted end-to-end. In the crystal, C—H...O and C—H...N hydrogen bonds link the molecules into chains extending along the a-axis direction.
