[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

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"

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

Epidemiological studies indicate an association between exposure to chlorinated drinking water and risk of intestinal cancer. In order to study this experimentally, we have examined the effects of 3,4-dichloro-5-hydroxy-2[5H]-furanone (mucochloric acid, MCA) and 3-chloro-4-(dichloromethyl)-5-hydroxy-2[5H]-furanone (MX), mutagenic and genotoxic compounds in

The cytotoxicity of the, in Salmonella, potent mutagenic compound, 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) and its structural analogue 3,4-dichloro-5-hydroxy-2[5H]-furanone (mucochloric acid, MCA), was studied in freshly isolated rainbow trout hepatocytes and gill epithelial cells by determining 86Rb-leakage and decrease in fluorescence intensity in
