Overview
C-Amylin is a synthetic long-acting amylin analog engineered with a C18 fatty-acid side chain for albumin binding and extended circulation. The compound has been studied in preclinical and clinical research as an amylin receptor (AMY-R) and calcitonin receptor (CT-R) co-agonist, with research interest in its role in satiety pathway biology distinct from GLP-1 receptor pharmacology (Larsen et al., 2021 — PMID: 34543252).
History
Amylin is an endogenous 37-amino-acid peptide co-secreted with insulin from pancreatic beta cells, discovered in the 1980s. C-Amylin was developed as part of research efforts to create a long-acting amylin analog suitable for weekly research administration protocols. Recent research has focused on its combination potential with GLP-1 receptor agonists for multi-pathway research designs (Enebo et al., 2021).

Compound Class & Mechanism
C-Amylin binds to amylin receptors (AMY1R, AMY2R, AMY3R) and calcitonin receptors (CT-R) in preclinical models. These G protein-coupled receptors signal primarily through Gs-mediated adenylyl cyclase activation, with downstream effects on area postrema and hypothalamic satiety signaling pathways that are distinct from GLP-1 receptor-mediated pathways.
Research has characterized cagrilintide’s pharmacodynamic profile in preclinical models, including effects on gastric emptying, postprandial glucagon secretion, and satiety pathway activation. Its C18 fatty-acid modification enables weekly research administration, and research interest has focused on its combination with GLP-1R agonists for multi-pathway metabolic research (Lau et al., 2021).
Research Findings
C-Amylin has been investigated in preclinical and clinical research spanning amylin pathway research, metabolic research, and combination research protocols with GLP-1R agonists. Published research has documented findings in the following domains:
Key Research Areas
- Amylin Receptor Pharmacology: AMY-R and CT-R receptor binding profile research
- Satiety Pathway Research: area postrema and hypothalamic satiety research
- Metabolic Pathway Research: preclinical body composition and glucose research
- Combination Research Protocols: amylin + GLP-1R co-administration research designs
Collectively, [C-Amylin] represents an emerging research tool for investigating amylin-pathway biology independently of and in combination with GLP-1R-mediated research in preclinical environments (Lau et al., 2021).
Research Context
Researchers study [C-Amylin] to investigate amylin and calcitonin receptor pharmacology in the context of long-acting administration profiles, and to explore multi-pathway research designs combining amylin receptor agonism with GLP-1 receptor agonism. The compound’s receptor profile makes it distinctive among modern metabolic research compounds.
