PL-3994
PL-3994 is a natriuretic peptide receptor-A (NPR-A) agonist that is resistant to neutral endopeptidase and acts as a bronchodilator. PL-3994 produces concentration-dependent relaxation of pre-contracted guinea-pig trachea with an IC50 value of 42.7 nM.

Biological Activity
PL-3994 has high affinity for recombinant human, dog, or rat NPR-As with Ki values of 1 nM, 41 nM, 10 nM, respectively. And PL-3994 binds to hNPR-C with Ki of 7 nM, while there is no effect on cGMP generation in hNPR-B[1].
PL-3994 induces dose-dependent cGMP generation in human, dog, and rat NPR-As with EC50s of 2 nM, 3 nM, and 14 nM, respectively[1].
PL-3994 (0.1 nM-100 mM; 5-20 min) elicits a potent, concentration-dependent but small relaxation of pre-contracted human precision-cut lung slices (hPCLS)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
PL-3994 is resistant to degradation by human neutral endopeptidase (hNEP) (92% remaining after 2 h), whereas the natural ligands, ANP and CNP, are rapidly metabolized (≤1% remaining after 2 h)[1].
