Overview

This research introduces topological indices to improve prodrug nanoassembly design, suggesting a new approach for nanomedicine.

Key Points

  • The aim is to establish a predictive framework using chemical topology indices for designing small-molecule prodrug nanoassemblies.
  • Synthesized three types of SN38 prodrugs with varying topological architectures.
  • Analyzed the impact of topological indices on molecular characteristics and self-assembly behavior.
  • Evaluated the performance of nanoassembled prodrugs in terms of stability and antitumor efficacy.
  • Branched SN38 prodrugs demonstrated enhanced colloidal stability and prolonged systemic circulation.
  • Superior tumor accumulation was observed with the branched architecture compared to others.
  • Antitumor activity was significantly improved for SN38-Br nanocarriers, establishing the potential of the Nano-QSAR framework.
