| Bioactivity | Solithromycin (CEM-101) is an orally bioavailable, effective antimicrobial agent, with IC50s for inhibition of cell viability, protein synthesis, and growth rate are 7.5 ng/mL, 40 ng/mL, and 125 ng/mL for Streptococcus pneumonia, Staphylococcus aureus, and Haemophilus influenzae, respectively. Solithromycin binds to the large 50S subunit of the ribosome and inhibits protein biosynthesis[1]. | ||||||||||||
| Invitro | The IC50s values for Solithromycin on TNFα and CXCL8 release are 41.6 μM and 78.2 μM, respectively. Solithromycin markedly reduces MMP9 activity, with an IC50 of 14.9 μM[2].Solithromycin (0-333 μM; 72 hours; U937 and PBMC cells) suppresses lipopolysaccharide-induced TNFα release and phorbol 12-myristate 13-acetate (PMA)-induced matrix metalloproteinase 9 (MMP9) activity, and does not affect cell viability in monocytic U937 and PBMC cells[2]. | ||||||||||||
