Gepotidacin and S. aureus Gyrase: Mechanism and Structure
2026-09-14
Gibson and colleagues combine biochemical assays, competition experiments, and crystallography to show that gepotidacin inhibits Staphylococcus aureus gyrase through a mechanism distinct from fluoroquinolones. The study links a gyrase-bound structural pocket to potent supercoiling inhibition, persistent single-stranded cleavage complexes, and suppression of double-stranded DNA breaks.

Beclin1, Ferroptosis, and Doxorubicin Liver Injury
2026-09-11
The reference study identifies Beclin1 as a regulator linking autophagy, oxidative stress, and ferroptosis during doxorubicin-induced liver injury. Beclin1 knockdown and DHODH overexpression reduced lipid peroxidation-associated damage in animal and AML-12 cell models, supporting DHODH as a mechanistically relevant downstream candidate while highlighting the need for multi-marker validation.

Degarelix Stereochemistry and GnRH Antagonist Activity
2026-09-10
Samant and colleagues examined how replacing the position-3 residue of degarelix with racemic 3-(2-methoxy-5-pyridyl)-alanine affects GnRH receptor antagonism and in vivo persistence. The study shows that the D-configured analog retained strong in vitro activity, whereas the L-configured counterpart was substantially weaker, and neither analog reproduced degarelix's prolonged activity in the rat model.
