Antibiotic
Tylosin phosphate exerts antibacterial effects by binding to 23S rRNA of the bacterial ribosomal 50S subunit .
Tylosin phosphate also prevents growth of Gram-negative strains, with MICs of 64 μg/mL, 32 μg/mL, 512 μg/mL and 1 μg/mL for

, respectively.
Tylosin phosphate (10-500 mg/kg; s.c.) generally suppresses the elevated TNF-α and IL-1β levels and increases the IL-10 levels in the Lipopolysaccharide (LPS) -treated animals.
| Animal Model: | Balb/C mice (2-3 months old, 20-25 g) |
| Dosage: | 10 mg/kg, 100 mg/kg, 500 mg/kg |
| Administration: | Subcutaneous injection |
| Result: | Reduced the elevated TNF-α and IL-1β in LPS (250 µg)-treated mice but increased their IL-10 levels. |
