The organotin compounds dibulyltin (DBTC) and diphenyltin dichlorides (DPTC) were tested for trypanocidal activity on a Trypanosoma brucei-infected mice model. At a dose of 10 mg DBTC and 15 mg DPTC/kg/day for five consecutive days, they cleared the parasites from the peripheral blood of the infected mice. Subinoculation of some healthy mice with the homogenates of liver, spleen, kidney, cerebrospinal fluid and blood from the mice considered cured, showed a few cases of relapse. The LD50 of DBTC and DPTC are 90 mg/kg and 75 mg/kg respectively.
Résumé
Les composés de l'organotine, dichlorides de dibulyltine (DBTC) et de diphenyltine (DPTC) ont été testés pour leur activité trypanocide sur un modèle de souris infecté par Trypanosoma brucei. Aux doses de 10 mg de DBTC et 15 mg de DPTC/kg/jour cinq jours de suite, les parasites ont disparu du sang des souris infectées. Après sub-inoculation de souris en bonne santé avec des homogénats de foie, rate, rein, liquide cérébrospinal et sang de souris considérées comme guéries, quelques cas de rechute ont été observés. Les DL50 des DBTC et DPTC sont respectivement de 90 mg/kg et 75 mg/kg.
