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.

製品説明
体外実験
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].

体内実験
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].

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.
