Metabolite Identification
Common NameOctreotide
DescriptionOctreotide is only found in individuals that have used or taken this drug. It is the acetate salt of a cyclic octapeptide. It is a long-acting octapeptide with pharmacologic properties mimicking those of the natural hormone somatostatin.Octreotide binds to somatostatin receptors. These receptors are coupled via pertussis toxin sensitive G proteins which lead to inhibition of adenylyl cyclase. Octreotide binding to these receptors also stimulates phosphotyrosine phosphatase and activation of the Na(+)/H(+) exchanger via pertussis toxin insensitive G proteins.

Enzymes

General function:
Involved in peroxidase activity
Specific function:
Part of the host defense system of polymorphonuclear leukocytes. It is responsible for microbicidal activity against a wide range of organisms. In the stimulated PMN, MPO catalyzes the production of hypohalous acids, primarily hypochlorous acid in physiologic situations, and other toxic intermediates that greatly enhance PMN microbicidal activity.

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
Receptor for somatostatins-14 and -28. This receptor is coupled via pertussis toxin sensitive G proteins to inhibition of adenylyl cyclase.
