Key facts

What PT-141 is studied for

• Studying central nervous system melanocortin receptor (MC3R and MC4R) activation pathways.
• Comparing central hypothalamic neural signalling vs peripheral vascular PDE5 pathways.
• Investigating cyclic lactam-bridge peptide stability and blood–brain barrier receptor kinetics.

What the video covers

Each slide in the 60-second explainer follows one line of published laboratory work, not a medical outcome.

• 1. MC4R & MC3R GPCR Binding Binds central melanocortin-4 and melanocortin-3 receptors in hypothalamic nuclei.
• 2. Gs-Coupled cAMP Elevation Stimulates adenylyl cyclase, increasing intracellular cAMP and PKA phosphorylation.
• 3. Dopaminergic & Autonomic Readout Activates downstream central nitric oxide and dopaminergic neurotransmission pathways.
