Peptides Enabling Targeted and Efficient Drug Delivery
Peptides, made of amino acids linked by peptide bonds, offer high efficiency, low toxicity, and strong specificity for drug delivery. They address challenges like enzymatic breakdown, short half-lives, and poor cell penetration through targeted, cell-penetrating, responsive, and self-assembling designs. Combined with modifications and nanocarriers, peptides improve stability, bioavailability, and precise drug release in areas like cancer therapy and regenerative medicine.
Peptides vs Ligands: Targeting RNA Therapeutics
Peptide-guided carriers and ligand-conjugated systems both enable active targeting for RNA drugs, yet they vary in design and practicality. Peptides deliver single-chain precision, quick synthesis, and kidney clearance, unlike larger ligands such as antibodies, sugars, or aptamers that provide multivalent binding strength at the cost of added complexity and extended half-life. Choices depend on receptor details, production scale, and needed safety margins, as passive delivery falls short for precise RNA applications.
Targeting Peptides: Precision Guides for Drug Delivery
Targeting peptides, short chains of 5-30 amino acids, bind specifically to cell receptors and tissues to direct drugs and imaging agents accurately. They improve delivery efficiency, reduce side effects, and support precision medicine applications. Methods like phage display and computational design help create these versatile molecules for cancer therapy and beyond.
