カグリリンタイド

High-Purity Synthesis: Solid-phase synthesis combined with HPLC purification achieving ≥98% purity (HPLC-verified), with molecular weight and sequence confirmed by mass spectrometryLong-Acting Molecular Design: C20 fatty diacid modification enables reversible albumin binding, significantly extending in vivo half-life to support once-weekly dosing researchDual Receptor Targeting: Functions as a non-selective dual agonist of amylin receptors (AMYRs) and calcitonin receptors (CTR)Research-Grade Stability: Lyophilized powder ensures high stability; reconstituted solution maintains activity for cell and animal studies

Cagrilintide mimics the biological functions of native amylin, activating multiple central and peripheral signaling pathways:Central Appetite Regulation: Activates AMYR receptors in the hypothalamus and hindbrain regions (e.g., nucleus tractus solitarius, area postrema), inhibiting hunger signaling and promoting satietyDual Receptor Agonism: Simultaneously targets AMYRs and CTR. Evidence suggests that co-activation of both receptors may produce superior metabolic effects compared to selective AMYR agonists aloneGastric Emptying Delay: Reduces food intake and stabilizes postprandial glucose excursions by slowing gastric emptyingRenal Metabolic Modulation: In diabetic models, cagrilintide increases intracellular cAMP levels in cortical tubules and modulates ion transporter phosphorylation statusStructural biology studies reveal that while cagrilintide shares a highly similar receptor binding mode with native amylin, it induces distinctive conformational dynamics in receptor complexes—a feature that may underlie its superior clinical efficacy compared to earlier analogues.

Storage:Lyophilized Powder: Store at ≤ -20°C, protected from light, for optimal long-term stability.|Reconstituted Solution: Aliquot immediately and store at -80°C. Avoid repeated freeze-thaw cycles to preserve activity.Critical Notes:Research Use Only: Not for human or clinical use.Experimental Design: Account for its onset, plateau, and washout periods due to its prolonged action.Compliance: All research must adhere to institutional animal ethics and biosafety guidelines.
