O-Desmethyl-N-deschlorobenzoyl indomethacin is a metabolite of the non-steroidal anti-inflammatory drug (NSAID) and COX inhibitor indomethacin .1It is formed from indomethacin in isolated rabbit hepatocytes. O-Desmethyl-N-deschlorobenzoyl indomethacin (600 μM) decreases the viability of HL-60 leukemia cells when cultured with glucose oxidase.2It has also been used in the synthesis of prostaglandin D2receptor antagonists.3 1.Evans, M.A., Papazafiratou, C., Bhat, R., et al.Indomethacin metabolism in isolated neonatal and fetal rabbit hepatocytesPediatr.

N-Desmethyl sildenafil is a major metabolite of sildenafil . N-Desmethyl sildenafil is formed via oxidative metabolism of sildenafil by the cytochrome (CYP) P450 isoforms CYP3A4, CYP3A5, and CYP3A7.
O-desmethyl Brinzolamide is an active metabolite of the carbonic anhydrase (CA) inhibitor brinzolamide .1,2It inhibits CAII and CAIV (IC50s = 0.136 and 165 nM, respectively).1 1.Huang, Q., Rui, E.Y., Cobbs, M., et al.Design, synthesis, and evaluation of NO-donor containing carbonic anhydrase inhibitors to lower intraocular pressureJ.

Clomipramine D3 hydrochloride is the deuterium-labeled Clomipramine. Clomipramine is a serotonin transporter, norepinephrine transporter dopamine transporter blocker (Ki: 0.14, 54 and 3 nM).
N-desmethyl Eletriptan is a metabolite of eletriptan .1It is formed from eletriptan primarily by the cytochrome P450 (CYP) isoform CYP3A4 in human liver microsomes. 1.Evans, D.C., O’Connor, D., Lake, B.G., et al.Eletriptan metabolism by human hepatic CYP450 enzymes and transport by human P-glycoproteinDrug Metab.

N-desmethyl Rosiglitazone is a major metabolite of rosiglitazone , a potent and selective PPARγ ligand present in formulations that have been used to treat type 2 diabetes. Rosiglitazone is metabolized by the cytochrome P450 (CYP) isoform CYP2C8 to form N-desmethyl rosiglitazone.
N-Demethylvancomycin is a glycopeptide antibiotic that has been found inNocardia orientalis.1It is active against several strains ofS. aureusandS. epidermidisin vitroandin vivo.2Formulations containing N-demethylvancomycin have been used in the treatment of bacterial infections. 1.Boeck, L.D., Mertz, F.P., Wolter, R.K., et al.N-demethylvancomycin, a novel antibiotic produced by a strain of Nocardia orientalis.

Fluphenazine is a traditional antipsychotic compound that tightly binds the dopamine D2 receptor (Ki = 0.55 nM) and also reversibly inhibits calmodulin at micromolar concentrations. Fluphenazine-N-2-chloroethane is a derivative of fluphenazine that contains an alkylating chlorethylamine chain, which produces irreversible protein binding. It is a relatively selective, irreversible antagonist of D2 receptors both in vitro (IC50 = 100 nM) and in vivo, inactivating approximately 90% of D2 receptors in mice within 4 hours of treatment. Through this action, fluphenazine-B-2-chloroethane can be used to induce catalepsy in mice. It irreversibly inhibits calmodulin at higher doses (IC50 = 10 μM), which can sensitize cancer cells to TRAIL-induced apoptosis.
