Cholinesterases were detected in protoscolices of Echinococcus granulosus spectrophotometrically and electrophoretically. To characterize these activities as acetylcholinesterases or pseudocholinesterases, BW284C51 and the organophosphate anthelmintic Neguvón® were assayed as specific inhibitors of acetylcholinesterases, while Iso-OMPA was employed as specific inhibitor of pseudocholinesterases. We concluded that these Cholinesterase (ChE) activities would be considered as possible targets in chemotherapy.
Résumé
Des cholinestérases ont été détectées par spectrophotométrie et électrophorèse au niveau du protoscolex d'Echinococcus granulosus. Les activités - acétylcholinestérase et pseudocholinestérase - ont été caractérisées en utilisant des inhibiteurs spécifiques des acétylcholinestérases : BW 284 C51 et l'antihelminthique Neguvon®. L'Iso-OMPA a été utilisé en tant qu'inhibiteur spécifique des pseudocholinestérases. Les auteurs concluent que ces activités pourraient constituer une cible en matière de chimiothérapie.
