A study on the biochemical and ultrastructural effects of isatin on Echinococcus multilocularis metacestodes in Meriones unguiculatus is reported. In the metacestode, after an 18 day treatment period, the alkaline phosphatase and lactate dehydrogenase activities decreased and the acid phosphatase activity increased. Glucose and glycogen stores declined(More)
The effect of isatin on the E. granulosus cyst was studied. NMRI mice, which were infected with E. granulosus of sheep origin, were treated daily with isatin at a dose of 50 mg kg-1 for 18 days. Ultrastructural damage was observed in the treated cysts, including accumulation of lamellar stacks, electron-dense granules, autophagosomes and lipid vesicles.(More)
Alkaline phosphatases (E.C.3.1.3.1), membranous enzymes of the cestode Echinococcus multilocularis have been studied in the parasite and in the experimental host liver. Synthetic inhibitors interaction with metacestode alkaline phosphatases is reported. In regard to the alkaline phosphatases inhibition, the ethyloxanilate 2 is more efficient in the cestode(More)
Ethyl N-N-benzyl-methyl-oxamate is a N-substituted derivative of the oxamic acid, well-known as inhibitor of the lactate dehydrogenase activity. The biochemical and ultrastructural effects of this drug in Echinococcus multilocularis metacestodes and the repercussions in the livers of receptive host, Meriones unguiculatus, were investigated. This compound(More)
This study describes the synthesis of propargylic alcohols derived from isatin and their biochemical and morphological effects on Echinococcus multilocularis metacestodes in Meriones unguiculatus. Propargylic alcohols decreased the alkaline phosphatase and the lactate dehydrogenase activities of the metacestode selectively. The most effective compound, 1b,(More)
