Calvatic acid is a new antibiotic with both a carboxylic group and an azoxy function in the benzene ring. The relationship between structure and biological activity in this substance and one of its analog, phenylazoxyxyanide, was investigated. Isolated hepatocytes were used as an experimental system: the release of lactate dehydrogenase and the colchicine-binding activity of tubulin were first evaluated; effects were dose and time dependent. micromolar concentrations of these drugs determined a significant decrease of the glucose-6-phosphatase activity and a slight inhibition of aminopyrene demethylation. A toxic effect at the microsomal level and an interaction with the microtubular system are thus possible.

The effect of two new chelating agents-Tiron (4,5-dihydroxy-1,3-benzene disulphonic acid disodium salt) and succinic acid--on the mobilization of beryllium was studied. Animals were exposed to beryllium nitrate (1 mg kg(-1) i.p.) daily for 21 days. Administration of beryllium nitrate showed a marked decrease in haemoglobin percentage, blood sugar, serum alkaline phosphatase and serum protein and a significant increase in the activity of transaminases. Tissue protein and glycogen contents and the activity of alkaline phosphatase, adenosine triphosphatase and succinic dehydrogenase showed significantly decreased values, but beryllium nitrate provoked a considerable increase in the activity of acid phosphatase and glucose-6-phosphatase in the vital and reproductive organs. Significant improvement in the haematological and biochemical parameters was observed with Tiron but no therapeutic effect was seen with succinic acid. Atomic absorption spectrophotometry (AAS) also showed a decreased level of beryllium concentration in the liver and kidney after Tiron therapy.
