Apexbio Technology LLC Aclidinium Bromide 320345-99-1 10mg
Aclidinium Bromide (CAS 320345-99-1) is a long-acting muscarinic antagonist (LAMA) that selectively inhibits muscarinic acetylcholine receptors In binding assays it demonstrates high affinity for M1 M5 receptor subtypes with Ki values of 0 10 0 21 nM Functional studies reveal greater potency at endogenous M2 and M3 receptors with EC50 values of 17 4 nM and 5 3 nM respectively In vivo aclidinium bromide produces a concentration-dependent inhibition of acetylcholine-induced bronchoconstriction (EC50 2 5 23 1 g/mL in anesthetized guinea pigs) and suppresses pilocarpine-induced salivation in rats (EC50 38 g/kg) This compound is widely utilized in respiratory research for evaluating airway smooth muscle modulation via muscarinic receptor antagonism
