Metabolite Identification

Common Name

Thiamylal

Description

Thiamylal is only found in individuals that have used or taken this drug. It is a barbiturate that is administered intravenously for the production of complete anesthesia of short duration, for the induction of general anesthesia, or for inducing a hypnotic state. (From Martindale, The Extra Pharmacopoeia, 30th ed, p919)Thiamylal binds at a distinct binding site associated with a Cl^- ionopore at the GABA_A receptor, increasing the duration of time for which the Cl^- ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.

1. ATP-sensitive inward rectifier potassium channel 11

General function:: Involved in inward rectifier potassium channel activity
Specific function:: This receptor is controlled by G proteins. 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
Gene Name:: KCNJ11
Uniprot ID:: Q14654
Molecular weight:: 43540.4

Enzyme Details

3. ATP-sensitive inward rectifier potassium channel 8

General function:: Involved in inward rectifier potassium channel activity
Specific function:: This potassium channel is controlled by G proteins. 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 external barium
Gene Name:: KCNJ8
Uniprot ID:: Q15842
Molecular weight:: 47967.5
