General description

Omadacycline is an aminomethylcycline, a novel semisynthetic tetracycline-class antibiotic drug.(1)(2) It is distinguished from other tetracycline-class drugs like tigecycline and eravacycline at the C9 position with an aminomethyl substitution.(2)

Application

Mode of Action: Interferes with protein synthesis Antibiotic Activity Spectrum: Gram-negative bacteria and Gram-positive bacteria.

Biochem/physiol Actions

Omadacycline displays antimicrobial activities against a broad spectrum of organisms including Gram-positive, Gram-negative, anaerobic, and atypical bacteria.(3)(4) It inhibits bacterial protein synthesis by binding on the 30S subunit of the bacterial ribosome.(1)(2) Omadacycline is also effective against tetracycline efflux proteins in in vitro studies and protects against bacterial tetracycline resistance.(4) It has improved efficacy than other tetracycline drugs against acute bacterial skin and skin structure infections (ABSSSIs) and community-acquired bacterial pneumonia (CABP).(1)(2)(5) In nonclinical and ex vivo studies, omadacycline displays a low potential for cardiovascular toxicity.(6)

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

Omadacycline is novel, aminomethyl tetracycline antibiotic being developed for oral and intravenous (IV) administration for the treatment of community-acquired bacterial infections. Omadacycline is characterized by an aminomethyl substituent at the C9 position of the core 6-member ring. Modifications at this
