BAY-85-8501是一种高效、选择性的人中性粒细胞弹性蛋白酶 (HNE) 抑制剂，其 IC₅₀ 值为 65 pM。该化合物用于研究多种由 HNE 介导的炎症性疾病，如慢性阻塞性肺病 (COPD) 和其他呼吸系统疾病。

Secologanoside是从 Poraqueiba sericea 中分离的萜类化合物，对弹性蛋白酶的抑制作用较弱，IC50 值为 164 μg/mL，且对成纤维细胞具有中等程度的毒性。

Chrysophanol 8-O-glucoside, a natural product isolated and purified from the roots of Rheum with potent inhibitory effect on collagen- and thrombin-induced platelet aggregation, only inhibits platelet phosphatidylserine exposure, but not exerts direct inhibition on intrinsic factors, suggests that it may be of therapeutic benefit for the prevention of platelet-related cardiovascular diseases.

BAY-678 racemate is a racemate of BAY-678. BAY-678 is an orally bioavailable, highly potent, selective and cell-permeable inhibitor of human neutrophil elastase (HNE), with an IC50 of 20 nM. BAY-678 is also nominated as a chemical probe to the public via the Structural Genomics Consortium (SGC).

Sivelestat is a competitive inhibitor of human neutrophil elastase(IC50 = 44 nM and Ki=200 nM) and also inhibits leukocyte elastase obtained from rabbit, rat, hamster and mouse.

Sivelestat sodium is a competitive inhibitor of human neutrophil elastase (IC50 = 44 nM; Ki=200 nM); also inhibits leukocyte elastase obtained from rabbit, rat, hamster and mouse.

Alvelestat is an inhibitor of neutrophil elastase (NE) with the pIC50 of 7.9.

Elastase, Porcine pancreas 是一种来源于猪胰腺的弹性蛋白酶，对弹性蛋白和其他蛋白质底物具有高效水解作用。Elastase 主要用于蛋白质研究和组织工程应用。

JCP174是棕榈酰蛋白硫酯酶-1 (TgPPT1) 的抑制剂，这种酶在弓形虫体内负责去棕榈酰化作用。JCP174 还抑制猪胰腺弹性蛋白酶和人类白细胞弹性蛋白酶。
