Setmelanotide (RM-493) is a cyclic peptide full agonist of the melanocortin-4 receptor (MC4R, EC50 = 0.27 nM, Ki = 2.1 nM). Activation of MC4R stimulates intracellular cAMP signaling pathways within the central nervous system, which regulates energy homeostasis. Consequently, this agonism promotes downstream anorexigenic signals that mediate appetite suppression, decreased food intake, and enhanced energy expenditure in preclinical models. [1]

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
Pre-aliquoted for Longevity: Solid-state aliquots offer significantly longer shelf life compared to stock solutions, ensuring maximum stability for every use.
