oligopeptide triptorelin http://purl.bioontology.org/ontology/SNOMEDCT/395915003 http://purl.obolibrary.org/obo/CHEBI_63633 http://purl.obolibrary.org/obo/NCIT_C1267 https://en.wikipedia.org/wiki/Triptorelin https://www.wikidata.org/wiki/Q1992452 A synthetic decapeptide agonist analog of luteinizing hormone releasing hormone (LHRH). Possessing greater potency than endogenous LHRH, triptorelin reversibly represses gonadotropin secretion. After chronic, continuous administration, this agent effects sustained decreases in LH and FSH production and testicular and ovarian steroidogenesis. Serum testosterone concentrations may fall to levels typically observed in surgically castrated men. An oligopeptide comprising pyroglutamyl, histidyl, tryptophyl, seryl, tyrosyl, D-tryptophyl, leucyl, arginyl, prolyl and glycinamide residues joined in sequence. It is an agonist analogue of gonadotropin-releasing hormone. gonadotropin-releasing hormone analog
