Applications Testosterone-16,16,17-d3 17-Phenylpropionate, is the labeled analogue of Testosterone 17-Phenylpropionate (T155150), a Testosterone ester being misused by athletes in an attempt to improve sports performance. It can also be used as a therapy in glucocorticoid-treated patients to increase the circulating testosterone concentration.

Applications (1R,4S)-4-Amino-2-cyclopentene-1-carboxylic Acid Methyl Ester Hydrochloride is an intermediate used in the synthesis of ent-Abacavir (A105015), which is an enatiomer of Abacavir (A105000). Abacavir is a carbocyclic 2'-deoxyguanosine nucleoside reverse transcriptase inhibitor and an anti-HIV drug used to treat HIV infection (1). Intracellular enzymes convert Abacavir to its active form, carbovir-triphosphate (CBV-TP), which then selectively inhibits HIV reverse transcriptase by incorporating into viral DNA (2). Abacavir is metabolized in the liver by uridine diphosphate glucuronyltransferase and alcohol dehydrogenase resulting in inactive glucuronide and carboxylate metabolites, respectively.

Applications Isotope labelled (R)-(-)-2-Oxothiazolidine-4-carboxylic Acid (O870505), a precursor to glutathione (GSH) which is an important antioxidant in plants, animals and fungi.

Applications N1,O2'-Dimethyladenosine Monohydriodide-d3, is the labeled a analogue of N1,O2'-Dimethyladenosine Monohydriodide (D447411), is an intermediate useful in the synthesis of N6,O2'-Dimethyladenosine (D447415), which is naturally occurring modified nucleoside in RNA. It was reported in the preparation of alkylated adenosines as antihypertensive agents.
