1 Phosphoramidon potentiates the contractile response to endothelin-3, but not endothelin-1 in isolated airway tissue. phosphoramidon endothelin 3 Homo sapiens
2 Phosphoramidon (10 microM) markedly increased the contractile response to endothelin-3 in human and rabbit bronchus in vitro. phosphoramidon endothelin 3 Homo sapiens
3 In human tissue the contractile response to 0.3 microM endothelin-3 was significantly increased from 54 +/- 12% to 137 +/- 34% (of the response to 1 nM acetylcholine) in the presence of phosphoramidon. phosphoramidon endothelin 3 Homo sapiens
4 These results suggest that a phosphoramidon-sensitive enzyme (probably neutral endopeptidase) found in lung, may be responsible for local degradation of endothelin-3, but not endothelin-l in human and rabbit isolated bronchus. phosphoramidon endothelin 3 Homo sapiens
