General description

Solithromycin is a highly potent next-generation macrolid. the first fluoroketolid. which has potent activity against most macrolide-resistant strains. Solithromycin (CEM-101) is a novel fluoroketolide with improved antimicrobial effectiveness.

Application

Solithromycin has been shown to have potentent activity against S. pneumoniae as well as an extended spectrum of activity against CA-MRS. enterococc according to in vitro and in vivo research. Solithromycin has been used in:

  • the research on the anti-inflammatory effects of macrolides
  • the research of potency of solithromycin in comparison to other antimicrobials
  • in ithe research of the vitro activity of solithromycin against clinical N. gonorrhoeae isolates and reference strain

Biochem/physiol Actions

Mode of Action: Solithromycin binds to the large 50S subunit of the ribosome and inhibits protein biosynthesis. Like other ketolide. it should impair bacterial ribosomal subunit formation.

Antimicrobial spectrum: Active against bacteria like Legionella, Chlamydophila, Chlamydia, Mycoplasma, and Ureaplasma and against gonococci and other organisms that cause genitourinary tract infections

Features and Benefits

High quality antibiotic suitable for mulitple research applications

The continuing increase in antibiotic-resistant microorganisms is driving the search for new antibiotic targets and improved antimicrobial agents. Ketolides are semisynthetic derivatives of macrolide antibiotics, which are effective against certain resistant organisms. Solithromycin (CEM-101) is a novel fluoroketolide with improved
