Abstract: Borneol(Bo) and Arg-Gly-Asp(RGD) co-modified docetaxel(DTX) loaded MPEG-PLGA nanoparticles(DTX-Bo-RGD-NPs) were prepared to improve the therapeutic effect of DTX against glioma after intranasal administration. DTX-Bo-RGD-NPs were prepared by emulsification-solvent evaporation method, and their morphology, particle size, zeta potential, drug loading capacity(DLC), stability, and in vitro release properties were investigated. The fluorescence probe coumarin-6 loaded NPs were prepared for investigating the NPs' uptake property on C6 and 16 HBE cell models to evaluate in vitro targeting ability. The DiR loaded NPs were prepared for observing the fluorescence intensity at the brain tumor site after intranasal administration through in vivo imaging system in a C6 rat orthotropic model, evaluating the targeting ability in vivo. The anti-tumor effects of DTX-BoRGD-NPs were also investigated in such C6 rat orthotropic model in vivo. Animal welfare and experimental procedures are in compliance with the regulations of the Animal Ethics Committee of Shanghai University of Traditional Chinese Medicine. The results showed that DTX-Bo-RGD-NPs were spherical and uniformly distributed, with a particle size of about 140 nm and a zeta potential of-20 to-30 mV. The drug delivery system showed good stability and sustained release property in vitro, and favorable brain tumor targeting effect in vitro and in vivo. Such novel drug delivery system significantly improved the accumulation of DTX-Bo-RGD-NPs in tumor sites and displayed a higher brain tumor targeting efficiency, providing promising therapeutics of DTX for the treatment of glioma after intranasal administration.
