- W2969295206 abstract "We describe herein a chitosan nanocarrier for drug delivery applications obtained through the self-assembly of carboxymethyl-hexanoyl chitosan and dodecyl sulfate (CHC-SDS). Nanocapsules with spherical morphology were obtained in phosphate buffer at pH 7.4. These CHC-SDS nanocapsules showed no toxicity toward Jurkat cells (acute lymphoblastic leukemia) and were used to encapsulate a new pyrazoline (H3TM04) with antileukemia activity. The samples were characterized by dynamic light scattering (DLS) and Laser Doppler Micro-Electrophoresis. The encapsulation efficiency was higher than 96% (293.6 μg mL−1) and the H3TM04-loaded nanocapsules (CHC-SDS-H) had a negative surface charge (−29.8 ± 0.7 mV) and hydrodynamic radius of around 84 nm. For the first time, CHC-SDS-H were formed and the antitumoral cancer activity was proved. The in vitro assays showed the controlled release of H3TM04 from the CHC-SDS-H nanocapsules in phosphate buffer pH 7.4. The H3TM04 release data were described by the power law model, indicating that H3TM04 delivery occurred via an erosion mechanism. The cytotoxicity assays with Jurkat and K-562 cells (acute myeloid leukemia) demonstrated that the CHC-SDS-H nanocapsule decreases the half maximal inhibitory concentration (IC50). The study showed that CHC-SDS nanocapsules represent a promising nanocarrier for pyrazoline derivates that could be applied in leukemia therapy." @default.
