| 生物活性 | Clenbuterol (NAB-365) is aβ2-adrenergic receptoragonist with anEC50of 31.9 nM[1]. 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[2]. |
体外研究
(In Vitro) | 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[2].
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[3].
Cell Viability Assay[3] | Cell Line: | C2C12 cells. | | Concentration: | 0, 10, 100, and 200 μM. | | Incubation Time: | 24 and 48 hours. | | Result: | Treatment reduced viability of C2C12 cells for 24 and 48 h. |

体内研究
(In Vivo) | Treatment with Clenbuterol increases survival, rescues abnormalities in respiratory function and social recognition, and improves motor coordination in young maleMecp2-null (Mecp2–/y) mice[4].
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[5].
| Animal Model: | MaleMecp2–/yand femaleMecp2–/+mice[4] | | 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. |
