norfluoxetine

Norfluoxetine-d5 Hydrochloride is a deuterated compound of Norfluoxetine Hydrochloride. Norfluoxetine Hydrochloride has a CAS number of 57226-68-3. Norfluoxetine hydrochloride is an active metabolite of fluoxetine. Fluoxetine is an antidepressant drug.

Norfluoxetine-d5 is intended for use as an internal standard for the quantification of norfluoxetine by GC- or LC-MS. Norfluoxetine is an active metabolite of the antidepressant fluoxetine. It is formed from fluoxetine by the cytochrome P450 (CYP) isoforms CYP2C9, CYP2C19, and CYP3A. Norfluoxetine inhibits serotonin (5-HT) uptake in rat brain synaptosomal membrane preparations (Ki = 44.7 nM) and isolated human platelets (IC50 = ~15 nM). It has been found in the tissues of fish exposed to wastewater effluent.

Pentoxifylline-d6 is intended for use as an internal standard for the quantification of pentoxifylline by GC- or LC-MS. Pentoxifylline is a hemorrheologic agent. It increases the deformability of washed isolated human erythrocytes when used at a concentration of 100 µM. Pentoxifylline (1, 2, and 3 mM) inhibits ADP-induced platelet aggregation in isolated human whole blood. It inhibits thrombus formation induced by ADP in a hamster cheek pouch model when administered at doses of 5, 10, and 20 mg/kg. Formulations containing pentoxifylline have been used in the treatment of intermittent claudication.
