Herein, we fabricated the novel drug delivery system based on the self-assembly of two polyelectrolytes, poly-allylamine hydrochloride (PAH) and fucoidan, as the polycation and polyanion, resp., under mild conditions for cancer therapeutics. Furthermore, the designed polyelectrolyte complex nanoparticles as well as the methotrexate (MTX) disodium salt-loaded composites were systematically characterized using various techniques. The MTX loading in the nanoparticles was confirmed by zeta potential values that changed from -36.2 ± 2.2 to -28.3 ± 3.1 mV at a loading amount of 13.3 ± 1.2%. Furthermore, the obtained eventual particle sizes of nanoparticles were various with different concentrations and ratios of polyelectrolytes. The particle size also has increased from 130 ± 2.6 to 162.9 ± 2.3 nm after loading MTX. The drug release investigations in vitro at a pH value of 6.0 (acid environment) showed that the release of MTX was sustained in the conditions provided. Finally, we investigated the anticancer efficacy of MTX-loaded nanoparticles on MCF-7 cells and HeLa cells and the satisfactory results were obtained. Together, these self-assembled PAH/fucoidan nanoparticles with sustained drug release property will become the promising delivery system for cancer therapeutics. © 2018 Wiley Periodicals, Inc.

In the experiment, the researchers used many compounds, for example, Sodium (S)-2-(4-(((2,4-diaminopteridin-6-yl)methyl)(methyl)amino)benzamido)pentanedioate (cas: 7413-34-5HPLC of Formula: 7413-34-5).
Sodium (S)-2-(4-(((2,4-diaminopteridin-6-yl)methyl)(methyl)amino)benzamido)pentanedioate (cas: 7413-34-5) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. Amides can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.HPLC of Formula: 7413-34-5
