Understanding the Architecture of Peptide Conjugates
A peptide serves as the fundamental building block in these constructs, prized for its great variability and specificity along with low immunogenicity. When by TT Dean · 2024 · Cited by 83 — In this Perspective, we discuss how the conjugation of synergistic peptides and small molecules can be used to overcome complex disease states and resistance we discuss peptide conjugation, we are referring to the strategic process of attaching a chemical moiety to a peptide to modify its physical or biological properties.
At the core of this technology is the integration of diverse components. For instance, Peptide–drug conjugates (PDCs) have emerged as promising precision medicine tools that represent a unique class of molecules that integrate peptides and small molecule drugs to achieve increased therapeutic outcomes. The architecture typically involves:
* A targeting peptide designed for specific binding.
* A linker that ensures stability until the target site is reached.
* A payload (the drug or probe) that performs the intended function.
