the chemical world, evolution is mirrored in the origin of nanoscale
supramolecular structures from molecular subunits. The complexity
of function acquired in a supramolecular system over a molecular subunit
can be harnessed in the treatment of cancer. However, the design of
supramolecular nanostructures is hindered by a limited atomistic level
understanding of interactions between building blocks. Here, we report
the development of a computational algorithm, which we term Volvox
after the first multicellular organism, that sequentially integrates
quantum mechanical energy-state- and force-field-based models with
large-scale all-atomistic explicit water molecular dynamics simulations
to design stable nanoscale lipidic supramolecular structures. In one
example, we demonstrate that Volvox enables the design of a nanoscale
taxane supramolecular therapeutic. In another example, we demonstrate
that Volvox can be extended to optimizing the ratio of excipients
to form a stable nanoscale supramolecular therapeutic. The nanoscale
taxane supramolecular therapeutic exerts greater antitumor efficacy
than a clinically used taxane in vivo. Volvox can
emerge as a powerful tool in the design of nanoscale supramolecular
therapeutics for effective treatment of cancer.
