5-Methylchrysene, a carcinogenic polycyclic aromatic hydrocarbon with four fused rings, functions as an aryl hydrocarbon receptor agonist. It is generated through the incomplete combustion of organic matter and primarily detected in gasoline exhaust and tobacco smoke. Additionally, 5-Methylchrysene can be converted into mutagenic metabolites by cytochrome P450 enzymes 1A1 and 1B1.

Dehydroindapamide 是 Indapamide 的吲哚形式，用作定量分析标准，以测定 CYP3A4 介导的 Indapamide 代谢周转。该化合物表现出约为 Indoline 形式十倍的代谢周转率，并对 CYP3A4 具有略高的亲和力，从而支持药物代谢、酶动力学及药代动力学特征的深入研究。

(±)11-HETE is one of the six monohydroxy fatty acids produced by the non-enzymatic oxidation of arachidonic acid . The individual R and S isomers of racemic HETEs have been separated and identified using chiral phase HPLC. The racemic HETEs have been quantified as an index of lipid peroxidation using GC/MS.

Vildagliptin carboxylic acid metabolite is the major metabolite of the dipeptidyl peptidase 4 (DPP-4) inhibitor vildagliptin in humans. Vildagliptin carboxylic acid metabolite has an IC50 value of 477 μM for DPP-4 in human Caco-2 cells. It is formed from hydrolysis of the cyano group on vildagliptin.

Arasertaconazole, a sterol-14-alpha demethylation inhibitor, is used potentially for the treatment of vulvovaginal candcanidiasis.

TFM is a piscicide.1It is toxic to sea lamprey (P. marinus) with LC50values ranging from 1.97 to 2.11 and 2.05 to 2.21 mg/L for sac and swim-up fry, respectively, 1.6 to 2.45 mg/L for juveniles, and 1.6 to 1.63 mg/L for adults. It is also toxic to juvenile lake sturgeon (A. fulvescens) less than 100 mm in size but not to a variety of other fish species. TFM (50 μM) uncouples oxidative phosphorylation by 22 and 28% in isolated sea lamprey and rainbow trout (O. mykiss) liver, respectively.2Formulations containing TFM have been used as lampricides in the control of larval sea lamprey populations. 1.Boogaard, M.A., Bills, T.D., and Johnson, D.A.Acute toxicity of TFM and a TFM/niclosamide mixture to selected species of fish, including lake sturgeon (Acipenser fulvescens) and mudpuppies (Necturus maculosus), in laboratory and field exposuresJ.

Desmethyl bosentan is an active metabolite of the endothelin receptor antagonist bosentan .1Desmethyl bosentan (25 μM) activates the pregnane X receptor (PXR) in CV-1 monkey kidney cells expressing the human receptor in a reporter assay. 1.van Giersbergen, P.L.M., Gnerre, C., Treiber, A., et al.Bosentan, a dual endothelin receptor antagonist, activates the pregnane X nuclear receptorBr.

Electrolyte and fluid transport in the kidney are regulated in part by arachidonic acid and its metabolites. 16-HETE is a minor CYP450 metabolite of arachidonic acid released by the kidney upon angiotensin II stimulation that demonstrates stereospecific biological activity. 16(S)-HETE inhibits proximal tubule ATPase activity by as much as 60% at a concentration of 2 μM.

Clopidogrel-β-D-glucuronide 是 Clopidogrel 的代谢产物，直接与 CYP2C8 酶相互作用，并强烈抑制肝酶 CYP2C8。
