Several aryloxyacetic acid diuretics have shown hepatotoxicity in humans, yet there continues to be interest in developing these compounds because of the uricosuric properties of some of them. This study was designed to test the utility of the hepatocyte monolayer culture as a model for studying these compounds. In addition, an attempt was made to define the structural components that are common to hepatotoxicity. Ticrynafen, indacrinone, ethacrynic acid and A-49816, an investigational compound, were found to be toxic in hepatocyte cultures; thus, with the exception of indacrinone, paralleling the experience in humans. The toxic compounds share a ketodichlorophenoxyacetic acid chemical structure. A-56234, an investigational uricosuric, was also found to be toxic in cultures but has not been demonstrated to be hepatotoxic in humans in limited clinical experience. It does not possess the ketodichlorophenoxyacetic acid structure proper but may be metabolized to a closely related structure. Furosemide, which does not have the ketodichlorophenoxyacetic acid structure, was not toxic in hepatocyte cultures and has not been hepatotoxic in humans. Thus, the structure common to the toxic compounds is ketodichlorophenoxyacetic acid or a closely related compound. The hepatocyte monolayer system appears to be a good model for demonstrating toxicity and, perhaps, for predicting toxicity of new compounds under development.
