Impurity Abacavir EP Impurity E
Applications (1R,3S)-3-[2-Amino-6-(cyclopropylamino)-9H-purin-9-yl]cyclopentanemethanol (Abacavir EP Impurity E) is an impurity of Abacavir (A104990). 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.

Stability Hygroscopic
Applications 3-Hydroxyhexadecanoylcarnitine Inner Salt is a derivative of Carnitine, essential cofactor of fatty acid metabolism; required for the transport of fatty acids through the inner mitochondrial membrane. Synthetized primarily in the liver and kidney; highest concentrations found in heart and skeletal muscle. Dietary sources include red meat, dairy products, beans, avocado. Also 3-Hydroxyhexadecanoylcarnitine works similar to the endogenous non-toxic molecule L-Carnitine (C184110) whose bioavailablity is improved due to the transport systems in place for Carnitine.
