The invention relates to derivatives of pyrroloquinazolinediamine, more specifically derivatives of 7-(substituted)-7H-pyrrolo[3,2-F] quinazoline-1,3-diamines that are non-toxic and are also effective in the treatment of malaria, including
P. falciparum
and
P. vivax
strains. The derivatives are certain carbamate derivatives, succinimide derivatives, alkylcarboxamides derivatives and acetamide derivative, phthalimides, alkylamines and all other amide and imide derivatives and their 1-hydroxy analogs. The derivatives of the present invention are also soluble in common organic solvents to facilitate the purification in a large scale synthesis of the composition.

showed potent cell growth inhibition against four clones of Plasmodiumfalciparum (D-6, RCS, W-2, and TM91C235), with a 50% inhibitory concentration of approximately 0.01 ng/ml, and were highly active againstPlasmodium berghei, with 100% cure at doses from <0.1 mg/kg of body weight to 220 mg/kg. The carbamates and alkyl derivatives, however, showed weak activity againstPlasmodiumfalciparum cell growth
