CPT-loaded NPs with polyethylene glycol shells can increase its solubility in water and remain in circulation for a long time. This experiment has evaluated cytotoxicity and immune and subacute toxicity of CPT NPs. Camptothecin (CPT) was incorporated into biotin-F127-PLA or F127-PLA polymeric nanoparticles; a dialysis method was used for non-targeted CPT NPs and anti-CA125 antibodies for targeted CPT NPs. A cytotoxicity test was also conducted based on the growth inhibition of the mouse fibroblast-like L-929 cell line. The effects of the two CPT-loaded NPs on immunity were also determined through a carbon particle clearance rate assay. Each mouse was intraperitoneally injected with 0.4 ml/20 g.bw nanoparticles for 28 consecutive days in the subacute toxicity test. Results have showed that CPT NPs have reduced the toxicity of free CPT on the L-919 cells. The CPT NPs did not induce phag.. View more»
