Dual-responsive block copolymers effectively solubilize the anticancer drug doxorubicin (DOX) within micelles. These PMEEECL-PAE copolymers exhibit temperature and pH responsiveness suitable for targeted drug delivery applications.
Area of Science:
- Polymer Science
- Materials Science
- Computational Chemistry
Background:
- Dual-responsive block copolymers offer tunable properties for advanced applications.
- Solubilizing hydrophobic drugs like doxorubicin (DOX) remains a challenge in drug delivery.
Purpose of the Study:
- To investigate the self-assembly of dual-responsive PMEEECL-PAE block copolymers.
- To evaluate their efficacy in solubilizing the anticancer drug doxorubicin (DOX).
Main Methods:
- All-atom molecular dynamics (MD) simulations.
- MARTINI coarse-grained (CG) force field simulations.
- Scheutjens-Fleer self-consistent field (SCF) computations.
Main Results:
- DOX was solubilized with high efficiency (75-80%) within PMEEECL-PAE micelles.
- Loading efficiency decreased with increasing drug concentration.
- Responsive behavior occurs within suitable temperature and pH ranges for drug delivery.
Conclusions:
- PMEEECL-PAE copolymers demonstrate effective dual-responsive self-assembly for DOX solubilization.
- The studied copolymers are promising candidates for targeted anticancer drug delivery systems.
