Glucogeno sintasa en helmintos parasitos: inhibicion por benzimidazoles

The inhibitor effect of Benzimidazoles in the glycogen synthetase of helminthics parasites

Resumos

Se ha determinado el effecto inhibidor sobre la actividad Glucogeno sintetasa (E.C.2.41.11) por parte de cuatro antihelminticos: Albendazol, Mebendazol, Parbendazol y Tiabendazol. Observandose que en todos los casos, es el Parbendazol quien ha demostrado un mayor poder inhibidor sobre la glucógeno sintetasa de Ascaris suum, Fasciola hepatica y Moniezia expansa. El Tiabendazol es el anti-helmintico que menor efecto inhibidor ha presentado sobre la enzima en los tres parasitos objeto de nuestro estudio. Con el presente trabajo y otros previstos en la misma linea, se pretende aportar nuevos datos acerca del aun desconocido locus de acción de estos antihelminticos.

The inhibitor effect on the Glycogen synthetase (E.C.2.4.1.11) activity by four anthelmintics: Mebendazole, Parbendazole, Albendazole and Thiabendazole was determinated. The most inhibitor effect of Parbendazole on A. suum, F. hepatica and M. expansa, was observed. The lowest inhibitor effect of Thiabendazole, on all cases, was also observed. The aim of our study, and further studies on the same line, are to provide new reports about the unknown locus of actuation of these anthelmintics.

SUMMARY

The inhibitor effect on the Glycogen synthetase (E.C.2.4.1.11) activity by four anthelmintics: Mebendazole, Parbendazole, Albendazole and Thiabendazole was determinated. The most inhibitor effect of Parbendazole on A. suum, F. hepatica and M. expansa, was observed. The lowest inhibitor effect of Thiabendazole, on all cases, was also observed.

The aim of our study, and further studies on the same line, are to provide new reports about the unknown locus of actuation of these anthelmintics.
