| dithioerythritol | <chemical> (r*,s*)-1,4-dimercapto-2,3-butanediol. A compound that, along with its isomer, cleland's reagent (dithiothreitol), is used for the protection of sulfhydryl groups against oxidation to disulfides and for the reduction of disulfides to sulfhydryl groups. Pharmacological action: sulfhydryl reagents. Chemical name: 2,3-Butanediol, 1,4-dimercapto-, (R*,S*)- (12 Dec 1998) |

| dithionitrobenzoic acid | <chemical> 3,3'-dithiobis(6-nitrobenzoic acid). A standard reagent for the determination of reactive sulfhydryl groups by absorbance measurements. It is used primarily for the determination of sulfhydryl and disulfide groups in proteins. The colour produced is due to the formation of a thio anion, 3-carboxyl-4-nitrothiophenolate. Pharmacological action: sulfhydryl reagents. Chemical name: Benzoic acid, 3,3'-dithiobis(6-nitro- (12 Dec 1998) |
| dithiothreitol | <chemical> A reagent commonly used in biochemical studies as a protective agent to prevent the oxidation of sh (thiol) groups and for reducing disulphides to dithiols. Pharmacological action: sulfhydryl reagents, expectorants. Chemical name: 2,3-Butanediol, 1,4-dimercapto-, (R*,R*)- (12 Dec 1998) |
