Self-assembly and self-delivery nanodrug of bortezomib: a simple approach to achieve the trade-off between functionality and druggability.

Bortezomib, dietary tannic acid and an FDA-approved excipient poloxamer were used as building blocks without any chemical syntheses and modifications to construct a dynamic self-delivery nanodrug with high drug loading, outstanding stability, tunable size and pH-controlled release. This strategy with high druggability, reproducibility and productivity might be desirable and useful for pharmaceutical formulations of bortezomib.
