CAS#: 1196800-39-1 (HCl)

Description: Omadacycline, also known as PTK 0796 and Amadacyclin, is a novel first-in-class aminomethylcycline with potent activity against important skin and pneumonia pathogens, including community-acquired methicillin-resistant Staphylococcus aureus (MRSA), β-hemolytic streptococci, penicillin-resistant Streptococcus pneumoniae, Haemophilus influenzae, and Legionella. Omadacycline is active against strains expressing the two main forms of tetracycline resistance (efflux and ribosomal protection). The primary effect of omadacycline is on bacterial protein synthesis, inhibiting protein synthesis with a potency greater than that of tetracycline. The binding site for omadacycline is similar to that for tetracycline.

Biological target: Omadacycline, also known as PTK 0796 and Amadacyclin, is a novel first-in-class aminomethylcycline.
In vitro activity: Here, this study performed in vitro susceptibility testing on 10 Mycoplasma genitalium isolates against omadacycline, minocycline, tetracycline, doxycycline, moxifloxacin, levofloxacin, and azithromycin. Omadacycline was the most potent agent, with all MICs of ≤0.5 μg/mL. MICs were not affected by resistance to other agents, including resistance to other tetracycline class drugs. Reference: Microbiol Spectr. 2022 Dec 21;10(6):e0365422. https://pubmed.ncbi.nlm.nih.gov/36314935/
In vivo activity: In vivo efficacy of omadacycline was demonstrated using an intraperitoneal infection model in mice. A single intravenous dose of omadacycline exhibited efficacy against Streptococcus pneumoniae, Escherichia coli, and Staphylococcus aureus, including tet(M) and tet(K) efflux-containing strains and MRSA strains. The 50% effective doses (ED50s) for Streptococcus pneumoniae obtained ranged from 0.45 mg/kg to 3.39 mg/kg, the ED50s for Staphylococcus aureus obtained ranged from 0.30 mg/kg to 1.74 mg/kg, and the ED50 for Escherichia coli was 2.02 mg/kg.
