Disulfide Bridges in Defensins

Current Topics in Medicinal Chemistry, 2015
Defensins are small cationic cysteine rich peptides, which usually contain 18-45 amino acids and possess amphiphilic properties. The term "defensin" was coined as the sequences of rabbit and human leukin/phagocytin molecules were first reported in 1985.

Carbon disulfide nephropathy

American Journal of Kidney Diseases, 2000
A 45-year-old nondiabetic man presented with features resembling diabetic triopathy. He worked in a rayon manufacturing plant and was exposed to toxic levels of carbon disulfide (CS(2)). Clinical abnormalities included peripheral and central nervous system abnormalities as well as retinopathy, dyslipidemia, cardiovascular disease, and nephrotic ...

Chemical reduction of disulfides

1987
Publisher Summary This chapter discusses the chemical reduction of disulfides. Disulfides are easily and specifically reduced by thiols, which are the most used reagents for this purpose. However, the excess of the thiol used as a reductant has to be removed before it is possible to assay the newly generated SH groups.

Electrochemical reduction of disulfides

1987
Publisher Summary Electrochemical reduction of disulfides has been reported to give higher yields of thiols than alternative zinc-acid or borohydride reductions. The use of electrochemical reduction is exemplified by the low toxicity, high yield, selective analysis of urinary captopril [(S,S)-l-(3-mercapto-2-D-methyl-l-oxopropyl)-L-proline], an ...
