Structure-activity relationships of novel anti-malarial agents. Part 6: N-(4-arylpropionylamino-3-benzoylphenyl)-[5-(4-nitrophenyl)-2-furyl]acrylic acid amides.

We have demonstrated that the p-trifluoromethylphenylpropionylamino residue at the 2-position of the core structure leads to an active benzophenone-type anti-malarial agent. The attempt to improve water solubility by introduction of an amino group into the alpha-position of the arylpropionyl residue resulted in decreased activity.
