Melanotan II

Melanotan II / [Nle4,D-Phe7]-cyclo-α-MSH

Cyclic heptapeptide analogue of α-MSH with a lactam bridge between Asp and Lys residues. Potent non-selective melanocortin receptor agonist with high affinity at MC1R, MC3R, MC4R, and MC5R. MC1R activation drives eumelanin synthesis; MC4R agonism in the hypothalamus is associated with appetite suppression and autonomic effects studied in obesity and sexual function research models. Structurally distinct from the linear Melanotan I — the cyclic conformation confers greater metabolic stability and broader receptor promiscuity.

IGF-1 LR3

Long R3 Insulin-like Growth Factor-1

83-amino acid analogue of endogenous IGF-1 with an Arg3 substitution and 13-amino acid N-terminal extension that eliminates binding to IGF-binding proteins (IGFBPs), dramatically extending plasma half-life from ~10 min to ~20–30 h. Binds IGF-1 receptor (IGF-1R) with high affinity, activating PI3K/Akt and MAPK/ERK signaling cascades. Studied for skeletal muscle satellite cell proliferation, protein synthesis upregulation, and anti-apoptotic signaling in muscle and neuronal research models.

ARA290

ARA290 (Cibinetide) — Non-Hematopoietic EPO Analogue

11-amino acid cyclic peptide derived from the helix B surface of erythropoietin (EPO). Selectively activates the innate repair receptor (IRR) — a heterodimer of the EPO receptor (EPOR) and the common beta receptor (βcR) — without engaging the classical homodimeric EPOR responsible for erythropoiesis. IRR activation triggers downstream PI3K/Akt and JAK2/STAT3 anti-apoptotic and anti-inflammatory signaling in neurons, endothelial cells, and immune cells. Studied for neuroprotection in small fiber neuropathy, sarcoidosis-associated neuropathy, and ischemia-reperfusion injury models. Dissociation from hematopoietic activity eliminates the thrombotic and polycythemic risks associated with full-length EPO.

Adipotide

Adipotide (CKGGRAKDC-GG-D(KLAKLAK)₂)

Chimeric peptidomimetic composed of two functional domains linked by a GG spacer: a targeting domain (CKGGRAKDC) that homes to the prohibitin receptor expressed selectively on the vasculature of white adipose tissue, and a pro-apoptotic effector domain (D(KLAKLAK)₂) that disrupts mitochondrial membranes upon internalization. Selective vascular targeting induces apoptosis of adipose endothelial cells, triggering secondary adipocyte death via ischemia. Studied in non-human primate models for targeted adipose reduction without systemic toxicity at research doses. Represents a receptor-targeted approach to metabolic research distinct from GLP-1/glucagon axis compounds.

Mazdutide

Mazdutide (IBI362) GLP-1/Glucagon Dual Agonist

Long-acting GLP-1/glucagon dual receptor agonist engineered with a C18 fatty diacid acylation at Lys26 for albumin binding and extended half-life (~1 week). Simultaneous GLP-1R agonism drives insulin secretion, delays gastric emptying, and reduces appetite via central satiety signaling. Concurrent glucagon receptor (GCGR) agonism increases hepatic glucose output at low doses while potentiating energy expenditure and lipolysis in adipose tissue — a complementary mechanism to GLP-1R alone. Studied in Phase II/III clinical trials (Innovent Biologics) for obesity and type 2 diabetes, with data showing significant body weight reduction and glycemic improvement.

L-Carnitine

L-Carnitine (Free Base)

Quaternary ammonium compound biosynthesized from lysine and methionine. Functions as the obligate carrier for long-chain fatty acyl groups across the inner mitochondrial membrane via the carnitine palmitoyltransferase (CPT-1/CPT-2) shuttle system, enabling β-oxidation. Studied for roles in mitochondrial energy metabolism, acetyl-CoA buffering, reduction of exercise-induced oxidative stress, and modulation of insulin sensitivity in skeletal muscle. Also investigated in the context of male reproductive function and sperm motility research.

Melanotan I

Afamelanotide / [Nle4,D-Phe7]-α-MSH

Linear tridecapeptide analogue of α-melanocyte-stimulating hormone (α-MSH) with substitution of Nle at position 4 and D-Phe at position 7, conferring increased receptor affinity and metabolic stability. Acts as a potent agonist at melanocortin receptors MC1R and MC3R–MC5R. MC1R activation on melanocytes stimulates eumelanin synthesis via cAMP-mediated upregulation of tyrosinase. Also studied for photoprotective effects, anti-inflammatory modulation via NF-κB pathway, and erythropoietic protoporphyria (EPP) symptom reduction. Distinct from Melanotan II — does not carry the cyclic structure or the sexual side-effect profile associated with MC4R agonism.
