Omadacycline mesylate
Based on 33 publication(s) in Google Scholar
Omadacycline (PTK 0796) mesylate, a first-in-class orally active aminomethylcycline antibacterial, is a member of the tetracycline class of antibiotics. Omadacycline mesylate acts through the inhibition of bacterial protein synthesis by binding to the 30S ribosomal subunit. Omadacycline mesylate possesses broad-spectrum antibacterial activity against aerobic and anaerobic Gram-positive and Gram-negative bacteria, as well as atypical bacteria. Omadacycline mesylate can be used for the research of acute bacterial skin and skin-structure infections, community-acquired pneumonia, and urinary tract infections.

Biological Activity
|
Tetracycline |
Omadacycline displays activity against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE), beta-hemolytic streptococci, penicillin-resistant Streptococcus pneumonia (PRSP) and Haemophilus influenzae (H. influenzae), with MIC90s of 1.0, 0.25, 0.5, 0.25 and 2.0 μg/mL respectively[2].
Omadacycline is active against strains expressing tetracycline and other antibiotics resistance by ribosomal protection and active tetracycline efflux[2].
