LY377604 is a human β3-adrenergic receptor agonist and β1- and β2-adrenergic receptor antagonist with no sympathomimetic activity at the β1- and β2-adrenergic receptors. Combination of LY377604 and a norepinephrine-serotonin uptake inhibitor (sibutramine) was studied in the treatment of obesity. LY377604 would ameliorate side effect of sibutramine treatment (increase in blood pressure and heart rate due to activation of the sympathetic nervous system).

Cimaterol is a chemically stable nonselective agonist β1-, β2-, and β3-adrenoceptors. Cimaterol is used in sport as a stimulant and a fat burner that assists bodybuilders and strength athletes to get rid of body fats. Aside from shedding off fats, another benefit for using cimaterol for athletes is a boost in strength as well as an increase in muscle size or lean body mass. The increase in muscle size has been seen in previous animal studies when cimaterol is used. However, the reason behind the muscle gain is not identified yet, but the body has a very different response compared from taking in anabolic steroids. Experts in the field are saying that the increased nitrogen retention, that is known to cause by cimaterol, maybe the reason behind the muscle gain. Another great thing about Cimaterol is that, it can improve blood flow.

Bedoradrine (also known as KUR-1246 or MN-221), an ultra selective beta 2-adrenoceptor agonist, that participated in phase II clinical trials as an adjunct to standard therapy in the management of patients with acute exacerbation of asthma who did not respond to standard therapy. In addition, the drug was involved in trials for the treatment of preterm labor in obstetrical practice. Bedoradrine is also was studied in phase I of clinical trials for its use for treating chronic obstructive pulmonary disease, however, the efficacy for this disease was uncertain.

Carmoterol is a long-acting β2-adrenoceptor agonist with a rapid onset of action and potent bronchodilating activity. Carmoterol has a similar onset of action compared to salbutamol and formoterol, and a faster onset of action compared to salmeterol. Furthermore, the duration of tracheal smooth muscle relaxation is longer for carmoterol compared to both formoterol and salmeterol. In asthmatic patients, the PK of carmoterol is proportional to the dose, and nonlinear accumulation of the drug after repeated dosing treatments is negligible. In patients with persistent asthma carmoterol 2 µg administered once daily is as effective as formoterol 12 µg twice daily. Safety and tolerability results are similar between carmoterol and formoterol. There were no significant changes in ECG results, blood pressure or serum potassium or glucose levels

Colterol is a beta-2 adrenoreceptor agonist. Bitolterol, a diester prodrug of colterol, was marketed by Elan Pharmaceuticals for the treatment of reversible bronchospasm associated with asthma or chronic obstructive pulmonary diseases.

Levisoprenaline (l-isoproterenol) is beta1- and beta2-adrenoreceptor agonist. In Japan, continuous inhalation of levisoprenaline is a recommended treatment for pediatric patients with acute severe exacerbation. Compared with salbutamol, l-isoproterenol reduced modified pulmonary index score more rapidly. But in most countries do not recommend continuous inhalation of l-isoproterenol to treat pediatric patients with acute severe exacerbation of asthma due to worsening asthma control. Levisoprenaline was used to cause experimental chronic heart failure in rats.

Deterenol is a beta-adrenoceptor agonist. It is an effective nonmydriatic and nonmiotic hypotensive agent, which can be used in antiglaucoma treatment.
