Anti-angiogenic therapy can produce transient regression in tumor in case of Glioblastoma (GBM); however, no prolongation of patient survival rate had so far been achieved.


To address this problem, an effort was made to design and characterize a temozolomide loaded nanosystem for targeting the tumor vasculature in the brain using polymeric nanoparticles. It included the formation of Temozolomide (TMZ) loaded Solid-Lipid Nanoparticles (SLNs) and their conjugation with polysorbate-80 (P-80) which enhanced the penetration of drug to blood-brain barrier resulting in the enhancement of pro-apoptotic activity.


Conjugating nanoparticles with a tumor-penetrating polymer (P-80) further enhanced the therapeutic efficacy of the drug.


The animal studies indicated the enhanced potential of the developed system in the effective treatment of glioblastoma.
