used antiworm drug albendazole (ABZ) has been
recognized as an anticancer drug, while being safe for healthy cells.
However, its clinical application is limited due to low water solubility.
In this work, we incorporated ABZ into pH-responsive lipid-coated
calcium phosphate (LCP) nanoparticles to enhance anticancer efficacy.
LCP–ABZ nanoparticles doubled the ABZ solubility with a much
quicker release rate in the slightly acidic environment. LCP–ABZ
significantly improved cytotoxicity to B16F0 cells and reduced their
migration probably through enhanced apoptosis induction via reactive oxygen species overproduction. In a B16F0-bearing mouse
models, LCP–ABZ nanoparticles reduced the tumor size by 50–60%
at the total dose of only 15 mg (ABZ)/kg, more effective than commercial
albendazole and other ABZ nanoparticles. Overall, this research demonstrated
LCP nanoparticle as an effective platform to deliver ABZ for cancer
therapy, with safety to healthy tissues and the potential to inhibit
metastasis.
