Gepotidacin

Gepotidacin (GSK2140944) is a triazaacenaphtylene developed by GSK and belongs to the class of Novel Bacterial Topoisomerase Inhibitors (NBTI). This new antibiotic is currently being investigated in three phase 3 clinical trials.

Gepotidacin (GSK2140944) is a novel triazaacenaphthylene bacterial type II topoisomerase inhibitor.

Gepotidacin's primary mechanism of action involves inhibiting bacterial DNA replication, specifically targeting DNA gyrase (topoisomerase II) and topoisomerase IV. These enzymes are vital for bacterial processes such as replication, transcription, and cell division, as they regulate the topological state of DNA during these activities.
