Glioblastoma is a lethal neoplasm with few effective therapy options. As a mainstay in the current treatment of glioma at present, chemotherapeutic agents usually show inadequate therapeutic efficiency due to their low blood brain barrier traversal and brain targeting, together with tumor multidrug resistance. Novel treatment strategies are thus urgently needed to improve chemotherapy outcomes. Here, we report that nanomedicines developed by functionalizing the neurotropic rabies virus-derived polypeptide, RVG, and loading reduction-sensitive nanomicelles (polymer and doxorubicin) enable a highly specific and efficacious drug accumulation in the brain. Interestingly, curcumin serves as the hydrophobic core of the polymer, while suppressing the major efflux proteins in doxorubicin-resistant glioma cells. Studies on doxorubicin-resistant rat glioma cells demonstrate that the RVG-modified micelles exhibit superior cell entry and antitumor activity. In vivo research further showed that RVG modified nanomicelles significantly enhanced brain accumulation and tumor inhibition rate in mice, leading to a higher survival rate with negligible systemic toxicity. Moreover, effective suppression of recurrence and pulmonary metastatic nodules were also determined after the RVG-modified nanomicelles treatment. The potential of RVG-modified nanomicelles for glioma was demonstrated. Brain accumulation was markedly enhanced after i.v. administration. This unique drug delivery nanoplatform to the brain provides a novel and powerful therapeutic strategy for the treatment of central nervous system disorders including glioma. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Reference of 38215-36-0).
3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. The thiazole ring has been identified as a central feature of numerous natural products, perhaps the most famous example of which is epothilone.Various laboratory methods exist for the organic synthesis of thiazoles. For example, 2,4-dimethylthiazole is synthesized from thioacetamide and chloroacetone.Reference of 38215-36-0
