The aim of this study was to determine the effects of a pin‐to‐plate cold atmospheric plasma (CAP) on U‐251 MG three‐dimensional (3D) glioblastoma spheroids under different conditions. 3D tumorspheres showed higher resistance to the CAP treatment compared to 2D monolayer cells. A single CAP treatment was able to induce cytotoxicity, while multiple CAP treatments augmented this effect. CAP was also able to induce cytotoxicity throughout the tumoursphere, and we identified that reactive oxygen species(ROS) plays a major role, while H2O2plays a partial role in CAP‐induced cytotoxicity in tumour-spheres. We conclude that ROS‐dependent cytotoxicity is induced uniformly throughout glioblastoma and epidermoid …

Glioblastoma (GBM) is considered to be the most biologically aggressive type of brain tumour accounting for approximately 48% of all malignant primary brain tumours. GBM patients diagnosed have poor prognosis with a low five-year survival rate of
The aim of this study was to develop novel UA derivatives to enhance its bioavailability. Nine novel UA derivatives: three different diamine linkers, with Boc-protected and deprotected ends, and with folic acid were designed and synthesized to improve compound activity and/or delivery. The structures of the newly synthesised compounds were confirmed using mass spectrometry, FTIR, 1H NMR and 13C NMR. The structural activity …
