Biological Activity for Azithromycin

Azithromycin is a macrolide antibiotic. Inhibits 50S ribosomal subunit formation and elongation at transpeptidation step in gram-positive and gram-negative organisms. Orally active with improved pharmacokinetics over erythromycin in mouse models. Inhibits autophagy. Predicted to disrupt binding of SARS-CoV-2 spike protein to ACE2.

Licensing Information
