NEP-IN-1 是中性肽链内切酶 (NEP) 的抑制剂 (IC50 = 2 nM)。

Thiorphan 是选择性neprilysin 抑制剂 (IC50:6.9 nM) 。

Phenylalanylalanine（H-Phe-Ala-OH）是由苯丙氨酸和丙氨酸融合形成的二肽。它在蛋白质的不完全消化或分解过程中形成[1]。

Kelatorphan is an enkephalin degrading enzyme full inhibitor.

Met-Arg-Phe-Ala为一种肽类化合物，同时作为脑啡肽生成内肽酶（EGE）的有效竞争性抑制剂，应用于神经系统疾病的研究。

SQ28603 is a potent and selective neutral endopeptidase 3.4.24.11 (NEP) inhibitor.

Racecadotril-D5 is intended for use as an internal standard for the quantification of racecadotril by GC- or LC-MS. Racecadotril (T1176) is a prodrug form of the neprilysin (NEP)inhibitor thiorphan. In vivo,racecadotril reduces or prevents castor oil-induced diarrhea without delaying intestinal transit in rats when administered at doses of 80 or 100 mg/kg,respectively. It also decreases the duration of diarrhea and increases body weight gain in a neonatal gnotobiotic pig model of human rotavirus-induced diarrhea. Formulations containing racecadotril have been used in the treatment of acute diarrhea.

4-Aminobenzamidine dihydrochloride (p-Aminobenzamidine dihydrochloride) 是一种强胰蛋白酶 (trypsin)抑制剂，也是一种相对较弱的尿激酶型纤溶酶原激活剂 (uPA) 抑制剂 (Ki=82 μM)。4-Aminobenzamidine 可抑制 SCID 小鼠体内前列腺肿瘤的生长。

Toddalolactone ((+)-Toddalolactone) 是一种Toddalia asiatica 的主要成分，能够抑制重组人纤溶酶原激活物抑制物-1(PAI-1)的活性， IC50=37.31 μM。
