3-Hydroxy-N′-arylidenepropanehydrazonamides with Halo-Substituted Phenanthrene Scaffolds Cure P. berghei Infected Mice When Administered Perorally
摘要:
Structural optimization of 3-hydroxy-N'-arylidenepropanehydrazonamides provided new analogs with nanomolar to subnanomolar antiplasmodial activity against asexual blood stages of Plasmodium falciparum, excellent parasite selectivity, and nanomolar activity against the earliest forms of gametocyte development. Particularly, derivatives with a 1,3-dihalo-6-trifluoromethylphenanthrene moiety showed outstanding in vivo properties and demonstrated in part curative activity in the Plasmodium berghei mouse model when administered perorally.

active antiplasmodial agents. The most active compound 22 exhibited excellent antiplasmodial in vitroactivity with nanomolar inhibition of chloroquine-sensitive and multidrug-resistant parasite strains ofPlasmodium falciparum (with IC50 values of 5 and 12 nM against 3D7 and Dd2 strains, respectively) as well as low cytotoxicity in human cells. In addition, 22 showed strong in vivo activity in thePlasmodium

(EN) This invention provides a method of treating patients suffering from malaria whilst avoiding cardioarrhythmias, the improvement thereof comprising the administration of desbutylhalofantrine in place of halofantrine. Dosage of 500 mg every six hours for three doses on day one with repeat of that dosage on day 7 for a total dosage of 3000 mg is appropriate for most treatment purposes in adults. Desbutylhalofantrine may also be given at dosage of 50 to 1000 mg as a prophylactic measure. Dosage may be given daily or one day per week.(FR) L'invention concerne un procédé servant à traiter des malades atteints du paludisme, tout en évitant l'arythmie cardiaque, qui consiste à administrer la desbutylhalofantrine au lieu de l'halofantrine. Une dose de 500 mg toutes les six heures le premier jour et le renouvellement de cette dose le septième jour pour obtenir une dose totale de 3000 mg conviennent à la plupart des traitements chez l'adulte. On peut également administrer la desbutylhalofantrine en une dose de 50 à 1000 mg à titre prophylactique. On peut administrer cette dose de façon quotidienne ou hebdomadaire.
