Bithionol sulfoxide(Bitin-S) is a clinically approved anti-parasitic drug; has been shown to inhibit solid tumor growth in several preclinical cancer models. IC50 value: Target: anticaner agent Bithionol caused dose dependent cytotoxicity against all ovarian cancer cell lines tested with IC50 values ranging from 19 μM - 60 μM. BT treatment resulted in cell cycle arrest at G1/M phase and increased ROS generation [1]. Both bithionol and bithionol sulphoxide demonstrated in vitro toxicity to Neoparamoeba spp. at all concentrations examined (0.1 to 10 mg l(-1) over 72 h), with a comparable toxicity to freshwater observed for both chemicals at concentrations > 5 mg l(-1) following a 72 h treatment [2].
