PT-141, also catalogued as bremelanotide, is a cyclic melanocortin analogue studied for receptor subtype selectivity.\u003c\/p\u003e\n\u003cp\u003ePT-141 belongs to the same cyclic melanocortin family as MT-2 and is catalogued here with matching formula and mass figures. In the wider literature it is described as a metabolite-derived analogue, and it is studied chiefly for how its receptor preferences differ from the broader-binding compound it derives from.\u003c\/p\u003e\n\u003cp\u003eSelectivity is the whole research question around it. Where a compound binding several receptor subtypes at once produces results that are hard to attribute, a more selective analogue allows one subtype’s contribution to be isolated.\u003c\/p\u003e\n\u003cp\u003eThat makes the two a natural comparison pair in receptor panels, and PT-141 is most often studied alongside rather than instead of its relative.\u003c\/p\u003e\n\u003ch2\u003eKey research areas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMelanocortin receptor subtype selectivity research\u003c\/li\u003e\n\u003cli\u003eComparative binding panels against broad-spectrum analogues\u003c\/li\u003e\n\u003cli\u003eCyclic peptide structure-activity studies\u003c\/li\u003e\n\u003cli\u003eReceptor pharmacology in cell-culture models\u003c\/li\u003e\n\u003cli\u003eAnalogue derivation and metabolite research\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 lyophilized powder in a sealed research vial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize available:\u003c\/strong\u003e 10mg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack options:\u003c\/strong\u003e 1 vial, 3 vials, or 10 pack\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular formula:\u003c\/strong\u003e C50H68N14O10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular weight:\u003c\/strong\u003e 1025.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSequence:\u003c\/strong\u003e Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRelated melanocortin analogues\u003c\/h2\u003e\n\u003cp\u003eIts usual comparison compound is \u003ca href=\"\/products\/melanotan-ii-mt-2\"\u003eMT-2\u003c\/a\u003e, also stocked as a \u003ca href=\"\/products\/melanotan-2-nasal-spray\"\u003enasal spray\u003c\/a\u003e.
