Background

Solithromycin (CEM-101) is a new, potent and broad-spectrum fluoroketolide antibiotic [1][2].


Antibiotic is an antimicrobial used in the treatment and prevention of bacterial infection.


Solithromycin (CEM-101) is a broad-spectrum fluoroketolide antibiotic. CEM-101 exhibited high potency against diverse groups of Gram-positive and Gram-negative bacteria, including mycoplasma and ureaplasma, as well as bacteria associated with respiratory tract infections and skin infections, with MIC50 values of 0.015 μg/mL and 4 μg/mL, respectively [1]. Solithromycin (CEM-101) bound to the large 50S subunit of the ribosome and inhibited protein biosynthesis. In Streptococcus pneumoniae, Staphylococcus aureus, and Haemophilus influenzae, solithromycin inhibited cell viability, protein synthesis, and growth rate with IC50 values of 7.5, 40, and 125 ng/ml. Solithromycin also inhibition the formation of the 50S subunit [3]. In monocytic U937 cells, solithromycin inhibited TNFα/CXCL8 production and MMP9 activity. In PBMC isolated from chronic obstructive pulmonary disease (COPD) patients, solithromycin (10 μM) inhibited TNFα release and MMP9 activity. In monocytic U937 cells, solithromycin (10 μM) significantly inhibited NF-κB activity activated by oxidative stress [4].


In C57BL/6J mice, solithromycin also inhibited cigarette smoke-induced neutrophilia and pro-MMP9 production [4]. CEM-101 was also an effective antimicrobial for the prevention and treatment of intrauterine infection [2].
