## Pitch
Cyclic α-melanocyte-stimulating hormone analog. Researched for melanocortin-4 receptor activation pathway modeling.

## Mechanism
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide melanocortin-receptor agonist. In vitro it activates MC3R and MC4R subtypes with nanomolar affinity.

## Common in-vitro applications
### Melanocortin receptor signaling
cAMP assays in HEK293 cells expressing recombinant MC3R / MC4R.
Working range: `nM range`

### Receptor selectivity profiling
Comparative binding panels across MC1R–MC5R subtypes.
Working range: `nM range`

## Researchers commonly co-treat with
- **Melanotan-II** — Non-selective melanocortin agonist comparator.

## Storage and handling
- Lyophilized: −20°C or below, desiccated
- Reconstituted: 2–8°C, use within 30 days
- Light + air: Protect from light and air
- Solubility: Soluble in bacteriostatic water (0.9% benzyl alcohol)
