Metabolite Identification
Common NameTreprostinil
DescriptionTreprostinil is only found in individuals that have used or taken this drug. It is a synthetic analogue of prostacyclin, used to treat pulmonary hypertension. Treprostinil is marketed as Remodulin®. [Wikipedia]The major pharmacological actions of treprostinil are direct vasodilation of pulmonary and systemic arterial vascular beds and inhibition of platelet aggregation. In addition to treprostinil's direct vasodilatory effects, it also inhibits inflammatory cytokine. As a synthetic analogue of prostacyclin, it binds to the prostacyclin receptor, which subsequently induces the aforementioned downstream effects.

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
Receptor for ADP and ATP coupled to G-proteins that inhibit the adenylyl cyclase second messenger system. Not activated by UDP and UTP. Involved in platelets aggregation

General function:
Involved in DNA binding
Specific function:
Ligand-activated transcription factor. Receptor that binds peroxisome proliferators such as hypolipidemic drugs and fatty acids. Has a preference for poly-unsaturated fatty acids, such as gamma-linoleic acid and eicosapentanoic acid. Once activated by a ligand, the receptor binds to promoter elements of target genes. Regulates the peroxisomal beta-oxidation pathway of fatty acids. Functions as transcription activator for the acyl-CoA oxidase gene. Decreases expression of NPC1L1 once activated by a ligand
