In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Chitosan-based multi-liposomal complexes: Synthesis, biodegradability and cytotoxicity, published in 2021-04-30, which mentions a compound: 17739-45-6, mainly applied to chitosan liposomal complex biodegradability cytotoxicity; Biodegradation; Chitosan; Cytotoxicity; Liposome; Multi-liposomal container; Passive targeting mechanism, SDS of cas: 17739-45-6.
Anionic liposomes were electrostatically adsorbed onto the surface of cationic chitosan particles crosslinked by sulfate anions, forming multi-liposomal containers (MLCs) for encapsulation and delivery of bioactive substances. An increase in mol. mass of chitosan from 30 to 300 kDa results in a size increase of chitosan particles, from 200 to 400 nm. Being saturated by liposomes, chitosan particles give MLCs of 320-540 nm. Each chitosan particle carries between 60 and 200 liposomes. The proteolytic complex Morikrase, a mixture of enzymes with various specificities, induces degradation of MLCs down to particles of size 10-15 nm; the higher the mol. mass of chitosan, the slower the enzyme-induced MLCs′ degradation pH variation within 5.5-7 and cholesterol incorporation into the liposomal membrane both have a minor effect on the rate of MLCs′ biodegradation Both the MLCs and the products of their biodegradation show low cytotoxicity. These results are of interest for constructing biodegradable capacious carriers of bioactive substances.
Here is just a brief introduction to this compound(17739-45-6)SDS of cas: 17739-45-6, more information about the compound(2-(2-Bromoethoxy)tetrahydro-2H-pyran) is in the article, you can click the link below.
