Acetyl tetrapeptide-5
is used in cosmetic eye formulations to decrease puffiness, eye bags, and dark circles by reducing edema and protecting proteins such as SOD from glycation
Alanine
Ala / A · hydrophobic residue · neutral charge
AOD-9604
is studied as an anti-obesity peptide that can reduce weight gain and increase fat oxidation in obese animal models with generally neutral effects on IGF-1 and glucose metabolism in early human trials
Arginine
Arg / R · basic residue · positive charge
Argireline
is a topical cosmetic peptide reported to decrease dynamic wrinkles by partially mimicking the mechanism of botulinum toxin in a non-invasive manner
Asparagine
Asn / N · polar residue · neutral charge
Aspartic acid
Asp / D · acidic residue · negative charge
BPC-157
is investigated for accelerating healing of gastrointestinal mucosa, tendons, ligaments, bone, and nervous tissue in preclinical models, with anti-inflammatory and pro-angiogenic effects
Comparison
While Exenatide is used for type 2 diabetes treatment to improve glycemic control and modestly reduce body weight through GLP-1–like insulinotropic and glucagonostatic effects6768, PT-141 is FDA-approved for treatment of hypoactive sexual desire disorder in premenopausal women and is studied for sexual dysfunction in other populations, increasing sexual desire via CNS melanocortin pathways42101.
While Exenatide works as a 39-amino-acid exendin-4 peptide originally isolated from Gila monster venom that acts as a long-acting GLP-1 receptor agonist resistant to DPP-4 degradation67, PT-141 is the synthetic melanocortin receptor agonist bremelanotide, an analog of α-MSH that activates central MC3R and MC4R to modulate neuronal circuits governing sexual desire and arousal3242101.

PT-141
POMC
Exenatide and PT-141 are noticeably different, with limited direct overlap in their usual biological context. Their typical research and application settings separate fairly clearly: Exenatide is more often discussed in the realm of Metabolic and endocrine, whereas PT-141 is more often associated with the realm of Reproductive health. They also influence different molecular systems, with Exenatide tracking more closely to GLP-1 receptor while PT-141 centers more on GPCR receptor. Exenatide has a more venom-derived origin, while PT-141 is closer to synthetic analog background. Exenatide takes the form of a linear peptide, whereas PT-141 is closer to a cyclic peptide, Exenatide carries amidation features, while PT-141 instead reflects acetylation changes; while their sequence patterns also diverge, with Exenatide showing alpha-helical domain features and PT-141 showing protein-mimetic sequence features.
