Biochem/physiol Actions

Omadacycline (amadacycline, PTK 0796) is an orally active, potent tetracycline-class antibacterial against broad gram-positive and some gram-negative bacteria, including strains expressing the two main forms of tetracycline resistance (efflux and ribosomal protection). Omadacycline is also active against Haemophilus influenzae (H. influenzae) and atypical and anaerobic pathogens, including Legionella pneumophila, Mycoplasma spp., Ureaplasma spp., Bacteroides spp., and Clostridioides difficile. Unlike tetracycline, Omadacycline is active in vitro in the presence of the ribosomal protection protein Tet(O), despite its ribosomal binding site is similar to that of tetracycline.

Mechanism of action of the novel aminomethylcycline antibiotic omadacycline
Antimicrobial Agents and Chemotherapy, 58(3), 1279-1283 (2014)
James A Karlowsky et al.
Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 69(Suppl 1), S6-S15 (2019-08-02)
Omadacycline is a novel aminomethylcycline antimicrobial and semisynthetic derivative of tetracycline. In vitro, omadacycline displays potent activity against gram-positive and many gram-negative bacteria, including methicillin-resistant Staphylococcus aureus, Streptococcus pneumoniae, β-hemolytic streptococci, vancomycin-resistant Enterococcus, and Enterobacteriaceae. Omadacycline is also active against
