生物活性

Bremelanotide Acetate (PT-141 Acetate), a synthetic peptide analogue of α-MSH, is an agonist at melanocortin receptors including the MC3R and MC4R for the treatment of sexual dysfunction[1].

体内研究
(In Vivo)

Bremelanotide Acetate (50-200 μg/kg; s.c.; once) significantly increases proceptive solicitations in females primed with Estradiol benzoate+Progesterone or Estradiol benzoate alone in bilevel chambers[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Ovariectomized Long–Evans rats[2]
Dosage: 50, 100, 200 μg/kg
Administration: s.c.; once
Result: Significantly increased proceptive solicitations in females primed with Estradiol benzoate+Progesterone or Estradiol benzoate alone in bilevel chambers.
