Metabolite Identification
Common NameDofetilide
DescriptionDofetilide, also known as tikosyn or 1-mspmpe, belongs to the class of organic compounds known as sulfanilides. These are organic aromatic compounds containing a sulfanilide moiety, with the general structure RS(=O)(=O)NC1=CC=CC=C1. Dofetilide is a drug which is used for the maintenance of normal sinus rhythm (delay in time to recurrence of atrial fibrillation/atrial flutter [af/afl]) in patients with atrial fibrillation/atrial flutter of greater than one week duration who have been converted to normal sinus rhythm. Dofetilide is a very strong basic compound (based on its pKa). A tertiary amino compound that is N-ethyl-N-methylethanamine substituted by a 4-phenoxy and a 4-phenyl group at the terminal carbon atoms respectively.

Enzymes

General function:
Involved in monooxygenase activity
Specific function:
Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.

General function:
Involved in ion channel activity
Specific function:
Pore-forming (alpha) subunit of voltage-gated inwardly rectifying potassium channel. Channel properties are modulated by cAMP and subunit assembly. Mediates the rapidly activating component of the delayed rectifying potassium current in heart (IKr). Isoform 3 has no channel activity by itself, but modulates channel characteristics when associated with isoform 1

General function:
Involved in inward rectifier potassium channel activity
Specific function:
Probably participates in establishing action potential waveform and excitability of neuronal and muscle tissues. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. Can be blocked by extracellular barium and cesium
