Structural requirements for the sequestration of metabolically generated acetaldehyde
Nagasawa,Elberling,DeMaster
, p. 140 - 143 (1980)
Of a series of polyfunctional compounds containing amino, hydroxyl, or mercapto groups in conjunction with the carboxyl group, only the 1,2- or 1,3-disubstituted aminothiols, namely, D-(-)-penicillamine (1), L-cysteine (2), L-cysteinyl-L-valine (3), mercaptoethylglycine (4), and DL-homocysteine (12), showed any propensity to sequester acetaldehyde (AcH) when tested in vitro in a buffered system at pH 7.5. In vivo, however, only D-(-)-penicillamine (1) was effective in lowering ethanol-derived blood AcH in rats that had been treated with disulfiram and ethanol. These results suggest that, in addition to the functionality in the molecule, pharmacokinetic and metabolic factors must also be considered when designing AcH-sequestering agents for use in vivo.
Versatile synthesis of secondary 2-amino thiols and/or their disulfides via thiazolinium salts

Commercially available β-amino alcohols have been transformed into various secondary β-amino thiols and/or their disulfides by using methyl dithioacetate as a source of sulfur. The transformation involves a thiazolinium salt as a versatile key intermediate, which enables easy modulation of the product structure by varying the substituents on the hetero-cycle and the N-alkylating agent.
