(S)-Salmeterol（Cat No.:M115606） is a chiral selective form of salmeterol, a long-acting beta-2 adrenergic receptor agonist used primarily for the treatment of asthma and chronic obstructive pulmonary disease (COPD). It works by binding to beta-2 receptors in the airway smooth muscle, leading to muscle relaxation and bronchodilation that lasts up to 12 hours. The (S)-enantiomer is the active form of the drug, demonstrating greater efficacy and receptor specificity compared to its (R)-enantiomer. Salmeterol’s molecular design allows for sustained action, making it effective in maintaining prolonged airway openness and improving breathing in patients.
