N-Desethyl Bimatoprost (17-phenyl trinor PGF2α amide) is an F-series PG analog in which the C-1 carboxyl group has been modified to an unsubstituted amide. PG esters have been shown to have ocular hypotensive activity. PG N-ethyl amides were recently introduced as alternative PG hypotensive prodrugs. Although it has been claimed that PG amides are not converted to the free acids in vivo, studies have shown that bovine and human corneal tissue converts the amides of various PGs to the free acids with a conversion efficiency of about 10-20% relative to the hydrolysis of isopropyl esters. 17-phenyl trinor PGF2α amide would be expected to show the typical intraocular effects of latanoprost, but with the much slower hydrolysis pharmacokinetics of the PG N-amides.

Phosmet oxon is a toxic metabolite of phosmet, a phthalimide-derived, non-systemic, organophosphate insecticide used on plants and animals. It is mainly used on apple trees for control of codling moth, though it is also used on a wide range of fruit crops

Desmethylselegiline is an Enzyme Inhibitor.

Metabolism of 12(R)-HETE in corneal tissue produces predominantly the compound resulting from the loss of four carbon atoms through β-oxidation from C-1. This metabolite is 8(R)-hydroxy hexadecatrienoic acid (8(R)-HHxTrE) or 2,3,4,5-tetranor 12(R)-HETE.

Dihydro Dutasteride, a metabolite of Dutasteride, effectively inhibits five α-reductase isozymes.

2-Aminoflubendazole, a metabolite of benzimidazoles (BZ), belongs to a class of drugs effective against fungi, protozoa, and helminths.

(±)13,14-EDT是一种氧脂和腎上腺酸的代谢产物，通过细胞色素P450（CYP）途径形成。在50 nM的浓度下，它能激活分离的大鼠冠状小动脉平滑肌细胞中的大导电钙激活钾通道（KCa1.1/BK），并导致分离的猪小动脉扩张（EC50 = 12 pM）。(±)13,14-EDT还能使用TP受体激动剂U-46619预收缩的分离牛冠状动脉放松。

Perindopril acyl-β-D-glucuronide为Perindopril的代谢产物，属于ACE抑制剂类药物。

Etoricoxib N1'-oxide 是 Etoricoxib 的代谢产物，不抑制 COX-1，也不会显著抑制 COX-2。
