Tylvalosin
Based on 2 publication(s) in Google Scholar
Tylvalosin (Acetylisovaleryltylo?sin) is an orally active, broad-spectrum macrolide antibiotic with antimicrobial activity. Tylvalosin is an antiviral agent used to study PRRSV infection. Tylvalosin induces apoptosis. Tylvalosin also has anti-inflammatory activity, alleviates oxidative stress, and alleviates acute lung injury by inhibiting NF-κB activation.

Biological Activity
Tylvalosin (10 μg/mL; 0.5, 1 h) increases caspase-3 cleavage in porcine neutrophils, leading to DNA fragmentation during apoptosis[4].
Tylvalosin (0.1-10 μg/mL; 0.5 h) promotes endocytosis of porcine neutrophils by macrophages without changing phagocytosis[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Porcine neutrophils
-
Concentration:0.1, 1.0, or 10 µg/mL
-
Incubation Time:0.5, 1 h
-

-
Animal Model:PRRSV-free commercial breed piglets[5]
-
Dosage:800 mg/kg Aivlosin (20% Tylvalosin Tartrate Premix)
