The inactivation of the drinking water mutagen mucochloric acid (MCA) by reduced glutathione (GSH) was linked to the formation of an MCA-GSH conjugate, a nonmutagen in the Salmonella typhimurium (TA100) plate incorporation assay. Anaerobic formation of MCA-GSH is found now

The Salmonella typhimurium (TA100) mutagenic compound, mucochloric acid [3,4-dichloro-5-hydroxy-2(5H)-furanone (MCA)], was inactivated by in vitro N-acetylcysteine (NAC). The reaction of MCA with NAC at pH7 was second order and gave products 4, 5, and 6a that resulted from the displacement

The bacterial mutagen mucochloric acid was reacted with adenosine in aqueous solutions at 37 degrees C. In the HPLC chromatograms of the reaction mixtures two peaks of unidentified products were observed at longer retention times than the previously characterized "etheno"

Mucochloric acid, a genotoxic hydroxyfuranone found in chlorinated drinking water, was reacted with cytidine, adenosine, guanosine, and uridine. HPLC analyses with UV detection at 290 nm showed that one major product peak was formed in the reactions of cytidine, adenosine

[reaction: see text] The first direct reductive amination of mucochloric acid (1) has been accomplished. Reaction of 1 with various alkyl, aryl, and benzylamines, followed by reduction in the same pot, provides an efficient method of obtaining N-benzyl-3,4-dichloro-1,5-dihydro-pyrrol-2-one and N-aryl
