An in vitro placental barrier model based on human choriocarcinoma BeWo b30 cell line was considered as a method of preclinical study of the transport and toxicity of antitumor agents and other organic compounds. Low permeabilities were found for 5-fluorouracil as an example of hydrophilic compound and for doxorubicin as an example of a lipophilic compound with a high degree of binding to proteins and DNA and a high permeability was found for cyclophosphamide as an example of lipophilic compound with a low degree of binding to proteins. Using impedance spectrometry and cell viability assessment via reduction of resazurin to resorufin, a pronounced cytotoxic effect of doxorubicin and good tolerance of 5-fluorouracil and cyclophosphamide by the cells were shown for drug concentrations equal to the maximum concentrations in the patients’ blood during the treatment of breast cancer.
