Inhibitor Class | Inhibitor | % of Control (N = 3) |
---|---|---|
Neprilysin | SCH (10 μM) | 100 |
Thimet oligopeptidase | CFP (10 μM) | 102 ± 3 |
Thimet oligopeptidase | CFP (100 μM) | 97 ± 2 |
Neurolysin | Pro-Ile (1 mM) | 101 ± 2 |
Prolyl endopeptidase | ZPP (10 μM) | 96 ± 2 |
Serine | Aprotinin (80 μM) | 100 |

Inhibitors SCH39370 (SCH), 1-carboxy-3-phenyl-propyl (CFP), Pro-Ile, Z-prolyl prolinal (ZPP), aprotinin, soybean trypsin inhibitor (SBTI) and pepstatin A did not inhibit [125I]-Ang-(1-4) formation compared to control. Activity was assayed in a CSF pool of control and BMX animals (N=10) in the presence of 100 nM Ang-(1-7) and an inhibitor cocktail (AM, BS, CHYM, BSC, LIS) for 120 minutes at 37°C. Assays were repeated three times.
