Effect of cystamine on sperm and antioxidant parameters of ram semen stored at 4 °C for 50 hours [PDF]
Physical and chemical changes caused by oxidative stress in the spermatozoa membrane can reduce spermatozoa function and even lead to death. Cystamine (NH2-CH2-CH2-SH, β-mercaptoethylamine) is a natural substance that modulates the endocrine and ...

Studies on the acylation of 4-(2-aminoethylthio)-7-nitrobenzofurazan: the role of bases in promoting the formation of fluorescent S-acyl derivatives through S–N Smiles rearrangement [PDF]
The acylation of 4-(2-aminoethylthio)-7-nitrobenzofurazan has been investigated. Depending on the use of the base, a competitive Smiles rearrangement occurs during the acylation step leading to the formation of N-acyl and/or fluorescent S-acyl ...

Facile synthesis of cooperative acid-base catalysts by clicking cysteine and cysteamine on an ethylene-bridged periodic mesoporous organosilica [PDF]
A periodic mesoporous organosilica (PMO) that contains ethylene bridges was functionalized to obtain a series of cooperative acid-base catalysts. A straightforward, single-step procedure was devised to immobilize cysteine and cysteamine on the support ...

Restoration of CFTR function in patients with cystic fibrosis carrying the F508del-CFTR mutation [PDF]
Restoration of BECN1/Beclin 1-dependent autophagy and depletion of SQSTM1/p62 by genetic manipulation or autophagy-stimulatory proteostasis regulators, such as cystamine, have positive effects on mouse models of human cystic fibrosis (CF). These measures

Synthesis of diacylated γ-glutamyl-cysteamine prodrugs, and in vitro evaluation of their cytotoxicity and intracellular delivery of cysteamine [PDF]
To overcome the major disadvantages of cysteamine, the only registered treatment for the rare genetic disease cystinosis, nine prodrugs of γ-glutamyl-cysteamine (4) were synthesized for evaluation.

Myeloperoxidase-oxidase oxidation of cysteamine [PDF]
Cysteamine oxidation was shown to be catalysed by nanomolar concentrations of myeloperoxidase in a peroxidase-oxidase reaction, i.e. an O2-consuming oxidation of a compound catalysed by peroxidase without H2O2 addition. When auto-oxidation of the thiol was prevented by the metal-ion chelator diethylenetriaminepenta-acetic acid, native, but not heat ...

Controlled Synthesis of Silver Nanoparticles Using Double Reductants and Its Voltammetric Characteristics Study [PDF]
Constructing robust silver nanoparticles (AgNPs) with good shape and dispersibility is of particular interest in analytical applications. Herein, monodispersibility AgNPs with the average size of 20 nm have been successfully prepared via one-pot method ...

Spectroscopic Investigation of Cysteamine Dioxygenase
Thiol dioxygenases are mononuclear non-heme FeII-dependent metalloenzymes that initiate the oxidative catabolism of thiol-containing substrates to their respective sulfinates. Cysteine dioxygenase (CDO), the best characterized mammalian thiol dioxygenase, contains a three-histidine (3-His) coordination environment rather than the 2-His-1-carboxylate ...
