Dendrímero de poliglicerol carregado com complexo de boro-curcumina combinando anti-angiogênese e bnct com potencial para o tratamento do câncer

Abstract

In recent years, the use of therapeutic nanoparticles in cancer medicine has become important in order to obtain the specific distribution of chemotherapeutic agents, allowing the formulation of their own formulations. In this thesis the nanoparticles were prepared for application in boron neutron capture therapy (BNCT) and anti angiogenesis therapy. Polyglycerol dendrimer (PGLD) was used as a nanoplatform in this work because of its numerous advantages such as low toxicity and ease of functionalization. In this thesis the synthesis and characterization of nanoparticles based on PGLD for the treatment of head and neck cancer were performed. The polyglycerol dendrimer was conjugated to the boro-curcumin complex (PGLDBC). Then it was characterized by NMR (1H, 13C), FTIR and thermogravimetric analysis (TGA). The nanoparticles obtained were incubated under in vitro conditions with tumor cells of the SCC25 and SCC9 lines and their anticancer properties were evaluated by the TUNEL technique with LC50 of 15,44 mg/mL and 4,74 mg/mL. Confirming the potential of PGLDBC for the treatment of head and neck cancer.
