Description：Clenbuterol (NAB-365) hydrochloride, a selective β2-adrenergic agonist, enhances skeletal muscle strength and hypertrophy. Clenbuterol hydrochloride induces growth factor mRNA, activates astrocytes, and protects rat brain tissue against ischemic damage.

In Vitro：Clenbuterol increases lipolysis in rat primary adipocytes compared with control. Free glycerol release into the culture medium is 158% and 190% of control values in cultures containing 0.1, or 1 μM Clenbuterol, respectively[1].

In Vivo：Clenbuterol (0.01-0.5 mg/kg; i.p.; male Long-Evans rats) hydrochloride reduces the cortical infarct volume in Long-Evans rats as measured 7 days after permanent occlusion of the middle cerebral artery[2].

Animal Administration：Rats: Rats are randomly divided into two treatment groups. The control group is provided with standard chow and water ad libitum for 3 weeks, while the Clenbuterol group is provided with standard chow and treated for 3 weeks with Clenbuterol administered via the drinking water (30 mg Clenbuterol/L). Body weight and the amount of water consumed are recorded twice each week. After 3 wk, the animals are anesthetized and hindlimb muscles are excised[2].

Cell Assay：MTS assay is performed to determine the number of viable cells in culture. Cells are treated with 0 (vehicle only), 0.1, or 1 μM Clenbuterol for 6, 12, 24, or 48 h. The absorbance is measured at 490 nm in a plate reader determine the formazan concentration, which is proportional to the number of living cells in culture[1].
