Possible Anticancer Activity of Rosuvastatine, Doxazosin, Repaglinide and Oxcarbazepin

Background: Rosuvastatine, doxazosin, repaglinide and oxcarbazepin are therapeutic drugs available in themarket for the treatment of different diseases. Potential to display antitumor activities has also been suggested.The aim of the current study was to evaluate their in vitro effects on some human transformed cell lines. Materialsand
Methods: Cytotoxicity of the four drugs was tested in MCF-7, HeLa and HepG2 cells by the neutral red assaymethod and also the effect of rosuvastatine and doxazosin against Ehrlich Ascities Carcinoma Cells (EACC) bytrypan blue assay.
Results: Rosuvastatine exerted the greatest cytotoxic effect against HepG2 cells with an IC50value of 58.7±69.3; in contrast doxazosin showed least activity with IC50=104.4 ±115.7. Repaglinide inhibited thegrowth of both HepG2 and HeLa cells with IC50 values of 87.6±117.5 and 89.3±119.5, respectively. Oxcarbazepineshowed a potent cytotoxicity against both HeLa (IC50=19.4±43.9) and MCF7 cancer cells ((IC50=22±35.7).On theother hand the growth of EACC was completely inhibited by doxazosine (100% inhibition) while rosuvastatinehad weak inhibitory activity (11.6%) .
Conclusions: The four tested drugs may have cytotoxic effects againsthepatic, breast and cervical carcinoma cells; also doxazosine may inhibit the growth of endometrial cancer cells.Further investigations in animals are needed to confirm these results.
