Its cyclic design helps create a stable and clearly defined molecular profile for receptor-binding and signalling research.<\/p>\n<p>PT-141 is also known by its scientific name, Bremelanotide. The two names refer to the same active peptide compound.<\/p>\n<h2>Alternativa produktnamn<\/h2>\n<p>PT-141 may be identified under several names:<\/p>\n<ul>\n<li>PT-141<\/li>\n<li>PT141<\/li>\n<li>Bremelanotide<\/li>\n<li>Bremelanotide acetate<\/li>\n<li>Cyclic melanocortin

documentation.<\/p>\n<h2>Molekylstruktur<\/h2>\n<p>Bremelanotide is a synthetic cyclic heptapeptide with an acetylated amino terminus and a free acid at the carboxyl terminus.<\/p>\n<p>Its peptide structure is commonly represented as:<\/p>\n<p><strong>Ac-Nle-cyclo-(Asp\u2013His\u2013D-Phe\u2013Arg\u2013Trp\u2013Lys\u2013OH)<\/strong><\/p>\n<p>Important structural characteristics

make PT-141 particularly useful for cyclic peptide, receptor-binding and structure\u2013activity research.<\/p>\n<h2>Melanocortin Receptor Research<\/h2>\n<p>PT-141 is studied as a non-selective agonist of several melanocortin receptor subtypes.<\/p>\n<p>Relevant receptor systems include:<\/p>\n<ul>\n<li>MC1R<\/li>\n<li>MC2R<\/li>\n<li>MC3R<\/li>\n<li>MC4R<\/li>\n<li>MC5R<\/li>\n<\/ul>\n<p>The relative activity of PT-141 differs between receptor subtypes, with MC1R and MC4R

reference for examining how melanocortin receptor activation may influence centrally mediated signalling.<\/p>\n<h2>MC1R and Melanocyte Research<\/h2>\n<p>MC1R is strongly associated with melanocyte biology and pigmentation-related signalling.<\/p>\n<p>PT-141 may therefore also be relevant for laboratory research
