Suppression of premature ventricular complexes with the PDE5 inhibitor sildenafil: First clinical experience. [PDF]

Exp Physiol
Abstract The phosphodiesterase‐5 inhibitor sildenafil suppresses ventricular arrhythmias in a sheep model of drug‐induced long QT. In that study, ventricular arrhythmias were abolished by reducing premature ventricular complexes (PVCs) and delaying PVC onset, thus preventing ‘R‐on‐T’ ventricular tachycardia.

Sildenafil-evoked photoreceptor oxidative stress in vivo is unrelated to impaired visual performance in mice.

PLoS ONE, 2021
PurposeThe phosphodiesterase inhibitor sildenafil is a promising treatment for neurodegenerative disease, but it can cause oxidative stress in photoreceptors ex vivo and degrade visual performance in humans.

Accelerating Primary Screening of USP8 Inhibitors from Drug Repurposing Databases with Tree‐Based Machine Learning

Advanced Intelligent Discovery, EarlyView.
This study introduces a tree‐based machine learning approach to accelerate USP8 inhibitor discovery. The best‐performing model identified 100 high‐confidence repurposable compounds, half already approved or in clinical trials, and uncovered novel scaffolds not previously studied. These findings offer a solid foundation for rapid experimental follow‐up,
