Resumen de: WO2026042111A1
This invention, entitled "Temperature- and pH-Sensitive BPA-Targeted Chitosan-Poly(N-isopropylacrylamide)-FPBA Core-Shell Polymeric Nanoparticles Capable of Forming COF Structures in the BNCT Therapeutic Method," pertains to an anti-cancer pharmaceutical composition utilizing novel drug delivery methods. The application of the novel BNCT method is advantageous for cancers such as glioblastoma due to the challenge of crossing the blood-brain barrier. BNCT is a dual and targeted method wherein cancer cells, following the accumulation of ¹⁰B, are irradiated with thermal neutrons. Loading boron-containing compounds into nanoparticles can deliver a high concentration of boron to human glioblastoma cells. Temperature- and pH-sensitive nanoparticles of succinylated chitosan-poly(N-isopropylacrylamide) targeted with BPA are our concept for achieving endocytosis via sialic acid receptors on the surface of glial cells and for the targeted delivery of boron to these cells. By designing temperature- and pH-sensitive, BPA-targeted Chitosan-Poly(N-isopropylacrylamide)-FPBA core-shell polymeric nanoparticles with the capability of forming COF structures in order to simultaneously deliver BPA and FPBA, we aim to utilize the polymeric boron content to perform treatment via the BNCT method. Consequently, damage to healthy cells is reduced to a minimum, and even to zero.
