Nondestructive capture, release, and detection of circulating tumor cells with cystamine-mediated folic acid decorated magnetic nanospheres.

Journal of materials chemistry. B, 2020
Circulating tumor cell (CTC) detection and enumeration have been considered as a noninvasive biopsy method for the diagnosis, characterization, and monitoring of various types of cancers.

The ability of cystamine to bind DNA

Amino Acids, 2002
The DNA-binding properties of cystamine compared with natural occurring polyamines have been studied in vitro by means of ethidium bromide displacement assays, studies of DNA thermal stability and analyses of DNA-B/DNA-A transition. While the first two methods did not put in evidence any peculiar property in the binding capability of cystamine, CD ...

Cysteamine and cystamine

1987
Publisher Summary This chapter discusses about cysteamine and cystamine. Cysteamine (2-aminoethanethiol) is formed in mammalian tissues by the enzymatic hydrolysis of pantetheine, and has the role in the biosynthesis of hypotaurine. Cysteamine has been used therapeutically to treat cystinosis and sickle cell anemia, and has been used as a protective ...

One pot preparation of magnetic chitosan-cystamine composites for selective recovery of Au(III) from the aqueous solution.

International Journal of Biological Macromolecules, 2019
A novel magnetic chitosan adsorbent (CDF-CS) was synthesized by inserting magnetic particles into the crosslinked compound of chitosan (CS) and cystamine based on one-step method for selectively recovering Au(III) from aqueous solution.

Interaction of Cystamine and Cystamine Derivatives with Nucleic Acids and Nucleoproteins

International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1965
SummaryThe disulphides–cystamine, bis (2-guanidoethyl) disulphide (GED), dimethylcystamine, tetramethylcystamine, tetraethyl cystamine, cystine dimethyl ester and cystine diethyl ester–have been shown to interact with and become reversibly bound to calf thymus DNA, E. ccli RNA, and to calf-thymus and rat-liver nucleoproteins.

Simultaneous reduction and surface functionalization of graphene oxide by cystamine dihydrochloride for rubber composites

Composites. Part A, Applied science and manufacturing, 2019
The simultaneous reduction and functionalization of graphene oxide (GO) was achieved through a chemical grafting reaction with cystamine dihydrochloride (CDHC), a novel functional agent with dynamic disulfide bond.

Cystamine modulation of galactosamine-induced hepatotoxicity

Toxicology and Applied Pharmacology, 1984
The ability of cystamine treatment to protect against galactosamine-induced hepatic necrosis was investigated. Reduced hepatotoxicity was observed following galactosamine hydrochloride (400 mg/kg, ip) in male Sprague-Dawley rats that received cystamine dihydrochloride (300 mg/kg, po) 30 min prior to or 2, 4, 6, 8, or 12 hr after galactosamine.

The effect of cystamine on gastric secretion in the rat

Agents and Actions, 1979
The effects of cystamine on gastric secretion were studied in conscious and anaesthetized rat preparations. In the conscious gastric fistula rat cystamine inhibited the basal acid output but increased pepsin output. This pepsinogogue action was inhibited by both atropine and metiamide.
