3-Oxo-7-hydroxychol-4-enoic acid 是一种内源性代谢产物，可能作为肝胆疾病预后不良的重要指标。

10-Nitrooleic acid(CXA-10)是一种硝化不饱和脂肪酸和内源性信号分子，在氧化应激、炎症、代谢等多方面具有作用。

Evernic acid是一种发现于Evernia prunastri的天然代谢物，能够穿透血脑屏障，能够抑制TrxR1酶活性和NF-κB通路，在帕金森病模型中具有神经保护和抗炎作用，还具有抗癌、抗真菌和抗菌作用。

Isoprostanes are produced by the non-enzymatic, free radical peroxidation of phospholipid-esterified arachidonic acid. They have been used as biomarkers of oxidative stress, but they also have been found to have potent biological activity. ent-8-iso-15(S)-Prostaglandin F2α (ent-8-iso-15(S)-PGF2α) is a potent vasoconstrictor of porcine retinal and brain microvessels with EC50 values of 15 and 24 nM, respectively. This isoprostane is about ten-fold more potent than 8-iso-PGF2α in a whole blood platelet aggregation inhibition assay.

(-)-Jasmonoyl-L-isoleucine ((-)-JA-L-Ile)，为(+)-JA-L-Ile的对映体，是一种无活性的内源性激素。

Lentztrehalose A, a disaccharide microbial metabolite identified in Lentzea, exhibits a range of biological activities. This compound specifically inhibits M. smegmatis trehalase—an enzyme involved in trehalose metabolism—more effectively than trehalase from porcine kidney, with IC50 values of 0.67 mM and >20 mM, respectively. Additionally, Lentztrehalose A at a concentration of 100 mM promotes autophagy in MeWo melanoma and OVK18 ovarian cancer cells. When administered at 50 mg/kg daily, it enhances survival rates and impedes tumor growth in a Sarcoma 180 murine sarcoma model.

(±)-γ-Tocopherol是一种内源性代谢物和维生素E的一种形式，具有抗氧化和抗炎特性，能减少LPS和IL-1β诱导的前列腺素(PGE2)的合成。

Calcium 2-oxoglutarate is an intermediate in the production of GTP or ATP in the Krebs cycle. It is a reversible inhibitor of tyrosinase (IC50: 15 mM).

2-Myristyldipalmitin (PMP) 是一种棕榈酸甘油三酯，具有成为威尔逊氏病 (WD) 脂质标记物的潜力。
