| Sumario: | Nanomedicines typically use polymeric materials or liposomes as carriers. This provides targeting advantages but may lead to a series of defects, such as low drug loading, high risk in terms of safety, and high production costs. Herein, we report a computer simulation-assisted designing method for the construction of a novel doxorubicin (DOX) nanomedicine without any polymer carriers. We used a small molecular drug, bindarit (BIN), as a carrier of DOX to provide synergistic antitumor effects. First, the intermolecular forces between DOX and BIN were calculated for evaluating the interaction and potential conformation of the DOX/BIN complex. Then, the potential assembly ability of the DOX/BIN complex was predicated here by using dissipative particle dynamic stimulation. These computational simulation results suggested that BIN could form an amphiphilic complex with DOX through π–π stacking, hydrogen bonding, and electrostatic interaction and then self-assemble to nanoaggregates at the mesoscopic scale. Under the computational guidance, doxorubicin/bindarit nanoparticles (DOX/BIN NPs) in a spherical morphology were successfully prepared, and these NPs possess the original cytotoxic activity of DOX. Thus, this multiscale computer simulation-assisted design strategy can serve as an effective approach to develop nanomedicines using small molecules as a carrier. |
