Chiral filaments form from peptide-drug conjugates, with aromatic drug stacking driving assembly. Hydrogen bonds stabilize the structure later, guiding supramolecular design.
Area of Science:
- Supramolecular chemistry
- Computational chemistry
- Materials science
Background:
- Peptide-based supramolecular filaments are diverse.
- The role of auxiliary segments in chiral peptide assembly is unclear.
Purpose of the Study:
- Investigate chiral filament formation in peptide-drug conjugates.
- Understand the influence of aromatic drug moieties on self-assembly.
Main Methods:
- Computational study of self-assembly.
- Analysis of intermolecular interactions (π–π stacking, hydrogen bonding).
Main Results:
- Chirality is primarily mediated by π–π stacking between camptothecin (CPT) molecules.
- CPT stacking dictates early assembly stages; hydrogen bonding influences later morphology.
- Water molecules may be present within the filament core.
Conclusions:
- Aromatic segment interactions are crucial for chiral supramolecular assembly.
- Findings offer guidance for designing peptide conjugates with specific self-assembly properties.
