Preparation of blood-brain barrier-permeable paclitaxel-carrier conjugate and its chemotherapeutic activity in the mouse glioblastoma model

The per oral administration of compound 1, prepared by covalently attaching paclitaxel to a molecular carrier, shows good anti-tumor activity in the orthotopic mouse model of glioblastoma. The anti-tumor effects may be attributable to the cytotoxicity as well as the anti-angiogenic activity of the paclitaxel conjugate or paclitaxel itself in the brain parenchyma.
