Objective To construct and characterize the size-variable nano-delivery system PAMAM/DOX-pep,examine its physicochemical properties and evaluate its antitumor and targeting effects in vitro. Methods Small particle size PAMAM/DOX was obtained by physically encapsulating DOX within the hydrophobic cavity of the cationic polymer PAMAM. The large size nano-delivery system(PAMAM/DOX-pep)was formed by tandem linking small size nanoparticles by MMP-2 sensitive peptide pep(CPLGVRGC)using SMCC as a cross-linker. The particle size,potential,physical and chemical properties,inhibitory effect,cell uptake and nuclear targeting effect of each nanoparticle on mouse breast cancer cells(4T1)were detected. Results The particle size of PAMAM/DOX was about 10 nm,and the drug loading rate was 23%. PAMAMAM/DOX-pep,formed after cross-linking of peptide,had a particle size of about 200 nm,which could release DOX slowly at low pH,and remained stable,safe and non-toxic in vitro for 7 days with low hemolysis rate,and its cellular uptake amount and nuclear targeting rate increased significantly after co-incubation with MMP. Conclusions Size-variable nanoparticles overcome size-induced delivery barriers to target and deliver drugs to the 4T1 nucleus,providing a new strategy for the design of nano delivery systems.
