Gepotidacin mesylate hydrate is an orally active triazaacenaphthylene antibiotic and bacterial type II topoisomerase inhibitor. Gepotidacin mesylate hydrate inhibits bacterial DNA replication by blocking topoisomerase enzymes. Gepotidacin mesylate hydrate selectively inhibits topoisomerase IV and the B subunit of DNA gyrase.

Description

In Vitro

Gepotidacin is a potent inhibitor of gyrase-catalyzed DNA supercoiling (IC50 ≈ 0.047 μM) and relaxation of positively supercoiled substrates (IC50 ≈ 0.6 μM)^[1].
The MIC of Gepotidacin for E. coli isolates in Mueller-Hinton broth ranged from 1 to 4 mg/L^[2].
