Stibophen is an anthelmintic originally developed by Bayer that is used as a treatment for schistosomiasis{{cite journal | vauthors = Miller MJ, Lyon HP | title = Treatment of vesical schistosomiasis with stibophen | journal = The American Journal of Tropical Medicine and Hygiene | volume = 4 | issue = 6 | pages = 1049–56 | date = November 1955 | pmid = 13268811 | doi = 10.4269/ajtmh.1955.4.1049 }} by intramuscular injection. It is classified as a trivalent antimony compound. Brand names include Fouadin/Fuadin (named in honor of Fuad I of Egypt, who had enthusiastically supported its research and development).{{cite journal | vauthors = Khalil M, Betache MH | title = Treatment of Bilharziasis With a New Compound 'Fouadin.' | journal = Lancet | volume = 215 | issue = 5553 | pages = 234–35 | date = February 1930 | doi = 10.1016/S0140-6736(00)87344-4 }}{{cite journal | vauthors = Williamson TV, Dodson AI | title = The Specific Effect of 'Fouadin' (Fuadin) on Granuloma Inguinale: Preliminary Report | journal = JAMA | volume = 100 | issue = 21 | pages = 1671–76 | date = May 1933 | doi = 10.1001/jama.1933.02740210019007 }}

Mechanism of action

Stibophen inhibits the enzyme phosphofructokinase, which the worms need for glycolysis,{{cite journal | vauthors = Bueding E, Mansour JM | title = The relationship between inhibition of phosphofructokinase activity and the mode of action of trivalent organic antimonials on Schistosoma mansoni | journal = British Journal of Pharmacology and Chemotherapy | volume = 12 | issue = 2 | pages = 159–65 | date = June 1957 | pmid = 13446367 | pmc = 1509678 | doi = 10.1111/j.1476-5381.1957.tb00114.x }} at least partly by binding to the sulfhydryl (–SH) group of the enzyme.{{cite journal | vauthors = Su JG, Mansour JM, Mansour TE | title = Purification, kinetics and inhibition by antimonials of recombinant phosphofructokinase from Schistosoma mansoni | journal = Molecular and Biochemical Parasitology | volume = 81 | issue = 2 | pages = 171–8 | date = October 1996 | pmid = 8898332 | doi = 10.1016/0166-6851(96)02702-8 | doi-access = free }} Inhibiting glycolysis paralyzes the worms, which lose their hold on the wall of mesenteric veins and undergo hepatic shift, die, and are phagocytosed by liver cells.{{citation needed|date=December 2013}}
