Pararosaniline pamoate (CI 403-A) was developed as an orally active drug for the treatment of Schistosoma japonicum infection. The clinical trial has shown that capsules were safe and effective; in addition, this drug was well tolerated with a minimum of side effects, which were mostly mild and transient and did not require interruption of treatment. Besides, pararosaniline pamoate was an inhibitor of E.histolytica Hsp90 (EhHsp90) with promising activity against the parasite Pararosaniline pamoate, that causes amebiasis worldwide. Information about the current use of this drug is not available.
