The effect of p-nitrophenylarsonic acid on rat kidney glycosidases

The effect of p-nitrophenylarsonic acid on rat kidney glycosidases. Price, Robert G. (Dep. Biochem., Queen Elizabeth Coll., London, Engl.). Biochem. Soc. Trans., 5(1), 246-8 (English) 1977. CODEN: BCSTB5. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) After i.p. injection of p-nitrophenylarsonic acid (I) [98-72-6] (30 mg/kg) into rats, N-acetyl-.beta.-glucosaminidase (II) [9012-33-3], .beta.-galactosidase (III) [9031-11-2], and .beta.-glucosidase (IV) [9001-22-3] activities in kidney homogenates increased; the activity of II increased by 30% within 24 h of I injection, remained high for a further day and then decreased as did the activities of III and IV. Within 48 h of I injection, the urinary isoenzyme patterns of II, III, and IV were identical to those found in the kidney. A decrease in enzyme latency within the first 24 h was the earliest change in the properties of the kidney subcellular fractions isolated after I injection. The total activity recovered in all the subcellular fractions was increased in the initial 24 h of the expt. but then fell rapidly, particularly in the lysosomal and sol. fractions. Thus, the initial stimulation of lysosomal enzyme activity was accompanied by a marked decrease in latency which may be a prelude to a loss of hydrolytic enzymes into the cytosol and then into the urine. IV activity found in the urine in tubular necrosis originates from the kidneys.

Electrovalent aryluronium arylarsonates showed the highest fungicidal activity.
