In a study of the metabolism of the 19 members of the chloromononitrobenzene series (for summary and references see Table 4 of Bray, James & Thorpe, 1957 b) it was observed that in the rabbit several compounds were converted into mercapturic acids by replacement of a relatively labile chlorine atom. The formation of mercapturic acid by acetylcysteyldebromination of4-bromo-3:5-dichloronitrobenze...

Bacterial strain LW1, which belongs to the family Comamonadaceae, utilizes 1-chloro-4-nitrobenzene (1C4NB) as a sole source of carbon, nitrogen, and energy. Suspensions of 1C4NB-grown cells removed 1C4NB from culture fluids, and there was a concomitant release of ammonia and chloride. Under anaerobic conditions LW1 transformed 1C4NB into a product which was identified as 2-amino-5-chlorophenol ...

Reaction of thionyl chloride with 7-chloro-1-cyclopropyl-6-fluoro-1,4-dihydro-4- oxoquinoline-3-carboxylic acid 1 gave acid chloride 2. Compound 2 was reacted with glycine and D-glutamic acid to afford 2-(7-chloro-1-cyclopropyl-6-fluoro-4-oxo-1,4- dihydroquinoline-3-carbonyl) aminopantandioicacid 3a and 2-(7-chloro-1-cyclopropyl-6- fluoro -4- oxo-1,4-dihydroquinoline-3-carbonyl)aminoacetica...
