Abstract
A series of (E) 2-quinolinylmethylidene-5,7-dimethoxyindanones were prepared via base catalyzed Claisen-Schmidt condensation of 5,7-dimethoxy-1-indanone with the appropriate 2-chloro-3-formylquinoline derivative. Evaluation of their in vitro inhibition of β-hematin formation and hemoglobin hydrolysis and in vivo efficacy in rodent Plasmodium berghei suggest the antimalarial activity is derived from inhibition of hemoglobinolytic proteases.
