Core advantages and functions
Cagrilintide is a long-acting amylin receptor agonist designed based on the optimized molecular structure of natural amylin , and is an important representative of the next generation of weight management drugs . By specifically activating the amylin receptor , it exerts potent appetite suppression, delayed gastric emptying, and weight regulation effects in the central nervous system and peripheral tissues . It has demonstrated remarkable weight loss effects and metabolic improvement potential in studies of obesity, type 2 diabetes, and related metabolic syndromes , making it a key tool molecule for research on weight management mechanisms and the development of drugs for metabolic diseases .
✅Precise Mechanism of Action :
Central appetite suppression : Acts on the arcuate nucleus and parabrachial nucleus of the hypothalamus and the nucleus of the solitary tract in the brainstem , producing a strong and lasting feeling of satiety by activating amylin receptors.
Peripheral metabolic regulation :
Significantly slows gastric emptying rate and prolongs the time food stays in the stomach.
Inhibits postprandial glucagon secretion and improves blood sugar control
slightly increases energy expenditure and promotes the "browning" of white adipose tissue.
Long-acting pharmacokinetic characteristics : Modification with fatty acid side chains significantly prolongs the half-life, supporting a once-weekly dosing regimen .
Receptor selectivity : It has high affinity and selectivity for the amylin receptor, avoiding the risk of cross-reactivity with the calcitonin receptor.
✅Quality advantages of Chinese manufacturers :
Advanced synthetic modification techniques :
By employing solid-phase peptide synthesis combined with proprietary fatty acid side-chain targeted modification technology , the modification efficiency is ≥95%.
Optimized acylation reaction conditions ensure precise linkage of C18 diacid fatty acid chains.
Overall synthesis yield ≥80%, with large-scale production capacity reaching the kilogram level.
Multidimensional purification and quality control system :
Four-stage purification process : ion exchange → hydrophobic chromatography → molecular sieve → reversed-phase HPLC
Purity control : RP-HPLC purity ≥ 99.0%, SEC-HPLC monomer content ≥ 98.5%.
Structural confirmation :
Precise determination of molecular weight by mass spectrometry (MS)
Nuclear magnetic resonance (NMR) verification of fatty acid chain linkage sites
Circular dichroism (CD) analysis of secondary structure stability
Key impurity control :
Relevant peptide impurities: deleted sequences, oxidation products, deamidation products
Process impurities: fatty acid chain residues, organic solvent residues
Bioactivity verification :
In vitro receptor binding assay : Determination of affinity (KD value) for amylin receptor.
Functional cAMP experiment : Verifying receptor agonistic activity (EC50 value)
In vivo pharmacodynamic model : Validating weight loss effects using a diet-induced obesity (DIO) animal model.
Stability study :
Complete accelerated stability testing (40℃/75%RH, 6 months).
Long-term stability data (-20℃, 24 months)
Light stability and temperature cycling test
✅Product Features :
High potency and long-lasting effect : A single dose can produce an appetite-suppressing effect that lasts for up to a week.
High selectivity : Superior selectivity for amylin receptors compared to natural amylin
Good safety profile : Clinical studies have shown good safety and tolerability.
Synergistic potential : It has a synergistic effect with GLP-1 receptor agonists, significantly enhancing the weight loss effect.
Usage and Storage Guide
1. Reconstitution and preparation :
Special solvent :
The accompanying sterile reconstitution diluent (pH 7.4-8.0 buffer) must be used.
The use of ordinary saline, sterile water for injection, or other non-dedicated solvents is strictly prohibited.
Standard preparation procedure :
Slowly inject 1.0 mL of the special diluent along the inner wall of the vial.
Gently rotate the vial horizontally in your palm for 2-3 minutes.
A clear or slightly opalescent solution was obtained at 5 mg/mL.
Perform a second dilution with the same diluent or physiological saline containing 0.1% BSA.
Key points to note :
Avoid violent shaking and vortexing during the dissolving process.
The reconstituted solution should be used within 1 hour.
Before administration, visually inspect the solution to ensure it is clear and free of particles.
