Omadacycline (PTK 0796) hydrochloride，首创的具有口服活性的氨基甲基环素抗菌剂，是一种四环素类抗生素。Omadacycline hydrochloride 通过与 30S 核糖体亚基结合来抑制细菌蛋白质的合成。Omadacycline hydrochloride 对多种细菌表现出活性，包括好氧和厌氧革兰氏阳性细菌和革兰氏阴性细菌，非典型病原体。Omadacycline hydrochloride 可用于研究急性细菌性皮肤和皮肤结构感染，感染性肺炎和尿路感染。

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

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.
Omadacycline is active against strains expressing tetracycline and other antibiotics resistance by ribosomal protection and active tetracycline efflux. has not independently confirmed the accuracy of these methods. They are for reference only.

Omadacycline (0.11-18 mg/kg; a single i.v.) exhibits efficacy against Streptococcus pneumonia, Escherichia coli, and Staphylococcus aureus in mice systemic infection model, with ED 50 s ranging from 0.30 mg/kg to 3.39 mg/kg. has not independently confirmed the accuracy of these methods.
