PT-141, also known as bremelanotide, is a synthetic cyclic melanocortin peptide studied in laboratory models of melanocortin receptor signalling.\u003c\/p\u003e\n\u003cp\u003ePT-141 is a seven-amino-acid cyclic peptide derived from the melanocortin peptide family. Its structure incorporates norleucine and D-phenylalanine alongside a cyclic configuration designed to produce a more stable research analogue than naturally occurring melanocortin sequences.\u003c\/p\u003e\n\u003cp\u003eLaboratory interest centres primarily on melanocortin receptor activity, particularly signalling involving the MC3 and MC4 receptor pathways. These receptors are involved in a range of central nervous system signalling processes and make PT-141 useful in receptor-binding, pathway-response, and structure-activity research.\u003c\/p\u003e\n\u003cp\u003eIts compact cyclic structure also makes PT-141 a useful comparison compound when studying how peptide cyclisation and amino-acid substitution influence receptor affinity and molecular stability.\u003c\/p\u003e\n\u003ch2\u003eKey research areas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMelanocortin receptor signalling and receptor-binding studies\u003c\/li\u003e\n\u003cli\u003eMC3 and MC4 receptor pathway research\u003c\/li\u003e\n\u003cli\u003eCentral melanocortin signalling in laboratory models\u003c\/li\u003e\n\u003cli\u003eCyclic peptide structure-activity comparisons\u003c\/li\u003e\n\u003cli\u003ePeptide stability and conformational research\u003c\/li\u003e\n\u003cli\u003eComparative melanocortin research alongside MT-1 and MT-2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e pre-prepared liquid in a research spray bottle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize available:\u003c\/strong\u003e 30mg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack options:\u003c\/strong\u003e 1 spray bottle, 3 spray bottles, or 5 spray bottles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eOther PT-141 formats and related research peptides\u003c\/h2\u003e\n\u003cp\u003ePT-141 is also stocked as the \u003ca href=\"\/products\/pt-141\"\u003ePT-141 lyophilized vial\u003c\/a\u003e.
