Biological Activity
| Description | Spiramycin (Formacidine) is a 16-membered ring macrolide (antibiotic). |
|---|---|
| In vitro | Spiramycin reduces the hygromycin A protections of nucleotides in 23 S rRNA. [1] Spiramycin, a 16-membered macrolide, inhibits translocation by binding to bacterial 50S ribosomal subunits with an apparent 1:1 stoichiometry. Spiramycin acts primarily by stimulating the dissociation of peptidyl-tRNA from ribosomes during translocation. [2] Spiramycin at doses sufficient to inhibit protein synthesis in wild-type cells but not sufficient to kill either mutant or wild-type cells at the permissive temperature (30 degrees C). Spiramycin inhibits protein synthesis by stimulating the dissociation of peptidyl-tRNA from ribosomes. [3] Spiramycin shows dose-related inhibition of the proliferative response of PHA and PWM stimulated human mononuclear leucocytes (MNL). Spiramycin also induces a decrease in tritiated uridine (3H-UdR) uptake, which suggests that Spiramycin interferes with an early event in the cell cycle. [4] Spiramycin and, to a lesser extent, erythromycin increases total IL-6 production without affecting IL-1 alpha, IL-1 beta, or tumor necrosis factor alpha production in human monocytes stimulated with lipopolysaccharide. [5] Spiramycin shows good antimicrobial activity against species of Prevotella, Eubacterium, Peptostreptococcus, Bacteroides and Porphyromonas, and the effect is enhanced by the addition of Metronidazole.
