生物活性:
Clenbuterol (NAB-365) is a β2-adrenergic receptor agonist with an EC50 of 31.9 nM. Clenbuterol is a very potent inhibitor of the lipopolysaccharide (LPS)-induced release of TNF-α and IL-1β. Clenbuterol can inhibit the inflammatory process. Clenbuterol is a bronchodilator.

体内研究:
Treatment with Clenbuterol increases survival, rescues abnormalities in respiratory function and social recognition, and improves motor coordination in young male Mecp2-null (Mecp2?/y) mice. Clenbuterol is a bronchodilator. Clenbuterol (90 μg) is administered intratracheally to five horses. Peak serum concentrations of ~230 pg/mL are detected 10 min after administration, dropping to ~50 pg/mL within 30 min and declining much more slowly thereafter. Intratracheal administration of clenbuterol shortly before race time can be detected with this serum test.Animal Model:Male Mecp2?/y and female Mecp2?/+ mice
Dosage:5 or 0.1 mg/kg.
Administration:Injected i.p.; daily for 5 d, followed by a 2-d off period, repeated weekly
Result:Significantly improved the phenotype during the second but not first day of testing, implying a modest effect on motor coordination in Mecp2-null mice.

体外研究:
Clenbuterol (NAB-365) is a selective β2-adrenergic agonist (β2/β1 ratio = 4.0). Clenbuterol is a very potent inhibitor of the lipopolysaccharide (LPS)-induced release of TNF-α and IL-1β. Clenbuterol can inhibit the inflammatory process.Clenbuterol (10-200 μM; for 24 or 48 hours) decreases the viability of C2C12 myoblasts. Clenbuterol (100 μM) significantly decreases DNA synthesis. Clenbuterol (100 μM; for 12 h) increases the proportion of cells in G0/G1 phase. Clenbuterol treatment delays cell cycle progression. Clenbuterol (100 μM) induces cell cycle arrest, but not apoptosis, in C2C12 myoblasts.
