On July 31, 2018, Paenkaew, Sujittra; Rutnakornpituk, Metha published an article.SDS of cas: 6038-19-3 The title of the article was Effect of alkyl chain lengths on the assemblies of magnetic nanoparticles coated with multi-functional thiolactone-containing copolymer. And the article contained the following:
This work presents the synthesis of magnetite nanoparticle (MNP) coated with poly(N,N-diethylaminoethyl methacrylate)-b-poly(N-iso-Pr acrylamide-st-thiolactone acrylamide) [PDEAEMA-b-P(NIPAAm-st-TlaAm)] copolymer and its use in controlled drug release and bio-conjugation. TlaAm units in the copolymer were ring-opened with various alkyl amines to form thiol groups (-SH), followed by thiol-ene coupling reactions with acrylamide-coated MNP and then quaternized to obtain cationic copolymer-MNP assemblies (the size < 200 nm/cluster). The use of alkyl amines having various chain lengths (e.g., 1-propylamine, 1-octylamine, or 1-dodecylamine) in the nucleophilic ring-opening reactions of the thiolactone rings affected their magnetic separation ability, water dispersibility, and release rate of doxorubicin model drug. In all cases, when increasing the temperature, they showed a thermo-responsive behavior as indicated by the decrease in hydrodynamic size and the accelerated drug release rate. These copolymer-MNP assemblies could be used as a novel platform with thermal-triggering controlled drug release and capability for adsorption with any neg. charged biomols. The experimental process involved the reaction of 3-Aminodihydrothiophen-2(3H)-one hydrochloride(cas: 6038-19-3).SDS of cas: 6038-19-3
