New Class of Betulinic Acid-Based Nanoassemblies of Cabazitaxel, Podophyllotoxin, and Thiocolchicine

Betulinic acid is validated as a new self-assembly inducer for the formation of nanoparticles (NPs) in combination with different drugs. The target compounds are characterized by the presence of anticancer drugs acting on tubulin dynamics and of a linker that could be a carbon chain or a triazole-based one. Nanoparticles formed are characterized and their biological activity is evaluated.
