Bioactivity | CHF5407 is a selective, long-acting and competitive muscarinic M3 receptor antagonist. CHF5407 shows subnanomolar affinities for human muscarinic M1 (hM1), M2 (hM2) and M3 (hM3) receptors. CHF5407 shows a prolonged antibronchospastic activity[1]. |
Target | human muscarinic M1 (hM1), M2 (hM2) and M3 (hM3) receptors |
Invitro | CHF5407 has a very slow dissociation from M3 receptors (hM3; t1/2=166 min) and markedly short-acting at M2 receptors (hM2; t1/2=31 min)[1]. CHF5407 produces a potent (pIC50=9.0-9.6) and long-lasting (up to 24 h) inhibition of M3 receptor-mediated contractile responses to carbachol in the guinea pig isolated trachea and human isolated bronchus[1]. |
In Vivo | CHF5407 (0.1, 0.3, 1 nmol/kg; intratracheally; 100 ul; sigle dose) exerted a dose-dependent and potent inhibition of ACh-induced (20 g/kg; i.v.) bronchospasm, with an ED50 value of 0.15 nmol/kg in guinea pigs (450-550 g)[1]. |
