Cilastatin (MK0791) 是一种可逆的竞争性的肾脏脱氢肽酶 I 抑制剂，IC50为 0.1 μM。它抑制细菌金属叶内酰胺酶CphA 的IC50为 178 μM，可用作抗菌辅助剂。

Captopril (SA333) 是一种含巯基的，具有口服活性的血管紧张素转换酶(ACE)抑制剂 ，IC50=0.025 μM，广泛应用于高血压和充血性心力衰竭的研究。Captopril 也是NDM-1抑制剂，IC50=7.9 μM。

Ac-Ala-OH (N-Acetyl-L-alanine) 是鸟嘌呤核苷酸结合蛋白G(I) G(S) G(O) γ -2亚基、髓鞘碱性蛋白、GTP-结合核蛋白 Ran、原肌球蛋白 α - 4链、HIV-1 Rev 结合蛋白2、Xaa-Pro 二肽酶、胸腺酶 β -10、肌动蛋白样蛋白3、丙氨酸转氨酶、丝氨酸 苏氨酸蛋白磷酸酶PP1 - β催化亚基、10 kda 热休克蛋白(线粒体)、钙调蛋白和 β -1-syntrophin 的底物。

Maresin conjugates in tissue regeneration 3 (MCTR3) is a specialized pro-resolving mediator (SPM) synthesized from docosahexaenoic acid in macrophages. DHA is oxidized to maresin 1 , which is converted to MCTR1 by glutathione S-transferase Mu 4 or leukotriene C4 synthase, then to MCTR2 by γ-glutamyl transferase, and to MCTR3 by dipeptidase. MCTR3 accelerates tissue regeneration in planaria (1 and 100 nM) approximately as potently as MCTR2 and more potently than MCTR1. Pretreatment with MCTR3 prior to E. coli administration in mice reduces neutrophil infiltration, shortens the inflammatory resolution period, and increases phagocytosis of E. coli by macrophages. When administered at a dose of 100 ng 12h post E. coli infection in a mouse model of peritonitis, MCTR3 selectively reduces the amount of the eicosanoids PGD2 , PGE2 , PGF2α , and TXB2 in the exudate.

DPP-4-IN-8 (compound 27) 是一种高效的选择性DPP4抑制剂，具有 0.96 μM 的 Ki。该化合物能够抑制 Caco-2 和 HepG-2 细胞中的 DPP4 二肽酶活性，并剂量依赖性地降低 TNF-α、IL-6 和 IL-1β 的表达水平[1]。
