General description

6,6′-Dithiodinicotinic acid is reported as sulphydryl reagent. 6,6′-Dithiodinicotinic acid is reported to react with thiols, to afford a disulfide and 6-mercaptonicotinic acid. Interaction of 6,6′-dithiodinicotinic acid with the homogenates of Ehrlich ascites cells has been reported.

Application

6,6′-Dithiodinicotinic acid may be employed as:
  • specific thiol blocker to investigate the radioprotective effect of mercaptoethylamine on the thiol level of the outer cell membrane of the Ehrlich ascites tumor cells
  • modifier to investigate the polar microenvironment around the reactive Cys283 of rabbit muscle creatine kinase
  • dipyridyl-dithio substrate to evaluate the protein disulfide-thiol interchange activity of the auxin stimulated NADH: protein disulfide reductase (NADH oxidase) of soybean plasma membranes
  • water-soluble reagent in a study for introducing, in buffered saline, a reactive sulfhydryl group on water-soluble molecules bearing an alkyl-amino group
  • chromogen for sulfhydryl groups in the Ellman method for cholinesterase determinations
  • spectrophotometric determination of thiols and of total glutathione in human blood

In experiments with Ehrlich ascites tumor cells, using a specific thiol blocker, 6,6'-dithiodinicotinic acid, that does not penetrate the cell and therefore only binds SH-groups of peripheral areas of an external cell membrane, it was demonstrated that (1) the external

A simple method for introducing, in buffered saline, a reactive sulfhydryl group on water-soluble molecules bearing an alkyl-amino group is described. This method is based on the use of two water-soluble reagents: 2-iminothiolane and 6,6'-dithiodinicotinic acid. The first one is

A simple and rapid method for the determination of nanomole levels of biological thiols is described. The analysis is based on the combination of reverse-phase high-performance liquid chromatography with a postcolumn reaction with 6,6'-dithiodinicotinic acid.
