Hycanthone is a thioxanthene derivative of lucanthone with anti-schistosomal activity and potential antineoplastic activity. It was clinically available for the treatment of human schistosomiasis. Anti-helmintic action relies on its ability to inhibit worm monoamine oxidase and cholinesterases. Hycanthone produced immediate side effects such as hepatotoxicity and gastrointestinal disturbances, and was consequently withdrawn. Hycanthone inhibits apurinic endonuclease-1 (APE1) by direct protein binding. Hycanthone was used in the 1980s as antitumor agents, it was pulled out of Phase II trials.

Sample Use Guides

In Vivo Use Guide

Human schistosomiasis: single intramuscular dose (3.0, 2.5, 2.0, 1.5, and 1.0 mg/kg body weight).Unresectable pancreatic cancer: hycanthone was administered 60 mg/m2 intravenously within 2 to 4 hr during each day of the 5-day course of infusions during the first and fifth weeks of radiation therapy.

Route of Administration: Other

In Vitro Use Guide

Hycanthone stimulates motor activity of Schistosoma mansoni at concentrations of 10(-6) to 10(-5) M, and partially blocks the paralytic effects of carbachol and physostigmine.
