PT-141 (Ac-Nle-c[Asp-His-D-Phe-Arg-Trp-Lys]-OH) is a cyclic heptapeptide melanocortin agonist engineered for high MC-4 / MC-3 receptor selectivity and blood–brain-barrier permeability. Pre-clinical models and late-stage trials demonstrate centrally mediated increases in sexual arousal, libido, and penile tumescence independent of the nitric-oxide pathway, with transient blood-pressure elevations as the principal dose-limiting effect. Additional rodent data point to reward-circuit modulation, anti-inflammatory signaling, and analgesic potential via melanocortin-driven cytokine balance.
