Pravni status

Bremelanotid (PT-141) je jedinjenje u razvoju od strane kompanije Palatin Tehnologije za lečenje hemoragijskog udara i reperfuzijskih povreda. On funkcioniše putem aktivacije melanokortinskih receptora MC1R i MC4R, čime se moduliše inflamacija i ograničava ishemija.^[4]

On je originalno razvijen za upotrebu u lečenju impotencije^[5]^[6], ali je ta primena privremeno prekinuta 2008, nakon što je izražena zabrinutost zbog negativne nuspojave povećanja krvnog pritiska. Trenutno, Palatin i FDA pregovaraju o mogućem nastavku kliničkih ispitivanja faze 2 koristeći novi supkutani sistem doziranja leka koji ima malo uticaja na krvni pritisak.

Struktura

Bremelanotid je ciklični hepta-peptidni laktamski analog melanotropina (alfa-MSH) koji aktivira melanokortinske receptore MC3-R i MC4-R u centralnom nervnom sistemu. Njegova aminokiselinska sekvenca je Ac-Nle-ciklo[Asp-His-D-Phe-Arg-Trp-Lys]-OH ili ciklo-[Nle⁴, Asp⁵, D-Phe⁷, Lys¹⁰]alfa-MSH-(4-10). On je metabolit Melanotana II kome nedostaje C-terminalna amidna funkcionalna grupa.
