Ebelactone A（依贝内酯A）是一种来自Streptomyces sp.的霉菌酸β-内酯（mycolic acid β-lactone），是有效的酯酶（esterase）抑制剂，能够抑制酯酶、脂肪酶、N-甲酰甲硫氨酸氨肽酶活性，常用作低毒性的抗生素。

L-Arginine-7-amido-4-methylcoumarin hydrochloride是一种特异性的cathepsin H(组织蛋白酶 H)荧光底物和活性检测试剂，还能够作为氨基酸肽酶AP II的的底物。

TNP-470 is a methionine aminopeptidase-2 inhibitor. TNP-470 is also an angiogenesis inhibitor.

HFI-437是一种有效的非肽类胰岛素调节氨肽酶 (IRAP) 抑制剂，Ki为20 nM，同时也是一种认知增强剂。

Aclimostat (ZGN-1061) is a highly potent inhibitor of the MetAP2 enzyme that demonstrates promising efficacy and safety profiles in preclinical trials. In a mouse model of obesity and insulin resistance, ZGN-1061 exhibits comparable weight loss efficacy to beloranib, while also improving metabolic parameters. Additionally, ZGN-1061 induces consistent changes in gene transcription in HepG2 cells, further supporting its positive pharmacological effects.

ERAP2-IN-1 是一种非竞争性内质网氨基肽酶 2（ERAP2）抑制剂。ERAP2-IN-1 特异性抑制 ERAP2 肽水解活性，抑制 Arg-AMC 水解作用 (IC50: 27 μM) 和模型肽的水解活性 (IC50: 44 μM)。
