Bithionol is a synthetic sulfanediyl-bis-dichlorphenol), potent photosensitizer with the potential to cause serious skin disorders, formerly marketed as an active ingredient in various topical drug products. Bithionol has antibacterial and anthelmintic properties along with algaecide activity. Bithionol has been shown to be a potent inhibitor of soluble adenylyl cyclase (sAC, Adenylate cyclase type 10 ), an intracellular enzyme important in the catalysis of ATP to cAMP. Bithionol is the first known sAC inhibitor to act through the bicarbonate binding site via a mostly allosteric mechanism. Bithionol is used for treatment of tapeworm infections of dogs, cats, and poultry and for tapeworm and rumen fluke infections of sheep, horses, cattle, and goats.

Sample Use Guides

In Vivo Use Guide

After oral administration of single bithionol doses of 30 mg/kg body weight to healthy test persons (fasting, number not stated) no effects were observed, single oral doses of 50 mg/kg body weight caused diarrhoea and 150 mg/kg body weight prolonged diarrhoea, nausea and abdominal pains

Route of Administration: Oral

In Vitro Use Guide

Cytotoxic effect of BT (Bithionol) was evaluated against a panel of ovarian cancer cell lines (A2780 & A2780-CDDP OVACAR-3, SKOV-3, IGROV-1, and IGROV-1CDDP). A 20 mM stock of BT was prepared in DMSO and all the working dilutions were prepared in DMEM media. Ovarian cancer cell lines (5 × 103 cells/well) were plated into 96-well flat bottom plates (Corning, Inc., Corning, NY) and incubated for overnight. Cells were treated with different concentrations of BT ranging from 0.178 μM to 400 μM and further incubated for 48 hrs or 72 hrs. At least 4–6 hrs before the end of treatment time, presto blue reagent was added and incubated for total of 48 or 72 hrs and fluorescence measured (540 nm excitation/590 nm emissions). DMSO concentration was corrected to 1% in all wells.
