A team from the University of Southern Denmark has reported the discovery of a novel triaromatic pleuromutilin antibiotic candidate for the treatment of gram-positive bacterial infections. Hit evaluation and optimization of previously reported drug-like pleuromutilin conjugates with broad antibacterial activity led to the identification of compound [I] as the most potent and easily synthesizable antibiotic lead.
In a long and winding regulatory road that began with two complete response letters 15 years ago, Allschwil, Switzerland-based Basilea Pharmaceutica Ltd. finally gained U.S. FDA approval of its intravenous cephalosporin antibiotic, Zevtera (ceftobiprole medocaril sodium), to treat Staphylococcus aureus bacteremia, acute bacterial skin and skin structure infections (ABSSSI) and community-acquired bacterial pneumonia.
The EMA’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending approval of Pfizer Inc.’s Emblaveo (aztreonam-avibactam), an antibiotic combination that would offer a new option to patients with serious bacterial infections caused by multidrug-resistant gram-negative bacteria.
