Metabolite Identification

Common Name

Guanabenz

Description

Guanabenz is only found in individuals that have used or taken this drug. It is an alpha-2 selective adrenergic agonist used as an antihypertensive agent. [PubChem]Guanabenz's antihypertensive effect is thought to be due to central alpha-adrenergic stimulation, which results in a decreased sympathetic outflow to the heart, kidneys, and peripheral vasculature in addition to a decreased systolic and diastolic blood pressure and a slight slowing of pulse rate. Chronic administration of guanabenz also causes a decrease in peripheral vascular resistance.

Enzyme Details

1. Cytochrome P450 1A2

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 oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Most active in catalyzing 2-hydroxylation. Caffeine is metabolized primarily by cytochrome CYP1A2 in the liver through an initial N3-demethylation. Also acts in the metabolism of aflatoxin B1 and acetaminophen. Participates in the bioactivation of carcinogenic aromatic and heterocyclic amines. Catalizes the N-hydroxylation of heterocyclic amines and the O-deethylation of phenacetin.
Gene Name:: CYP1A2
Uniprot ID:: P05177
Molecular weight:: 58406.915

2. Alpha-2A adrenergic receptor

General function:: Involved in G-protein coupled receptor protein signaling pathway
Specific function:: Alpha-2 adrenergic receptors mediate the catecholamine- induced inhibition of adenylate cyclase through the action of G proteins. The rank order of potency for agonists of this receptor is oxymetazoline > clonidine > epinephrine > norepinephrine > phenylephrine > dopamine > p-synephrine > p-tyramine > serotonin = p-octopamine. For antagonists, the rank order is yohimbine > phentolamine = mianserine > chlorpromazine = spiperone = prazosin > propanolol > alprenolol = pindolol
Gene Name:: ADRA2A
Uniprot ID:: P08913
Molecular weight:: 48956.3
