Recommended solvent — Bacteriostatic water
In laboratory workflows, lyophilized research peptides are typically handled with suitable sterile diluents such as bacteriostatic water (BAC). For a compatible research-only solvent, see Bacteriostatic water.
Research Overview
PT-141 (bremelanotide) is a seven-residue peptide with the same lactam-bridged sequence as Melanotan 2; it differs only at the C-terminus, which ends in a free carboxylic acid instead of an amide. CAS 189691-06-3, molecular weight 1025.2 g·mol⁻¹; the vial contains a lyophilized peptide powder.
Its research footprint centres on central MC4 receptor signalling, hypothalamic control of sexual behaviour in rodents and melanocortin influence on vascular tone. Studied in vitro and in animal models; this research-grade material is not an approved medicinal product.
Studied in
- MC4R pharmacology — central receptor signalling
- Behavioural neuroscience — rodent sexual behaviour models
- Cardiovascular physiology — blood pressure and vascular tone
- Structure–activity — comparison with MT-II
