Bewertung des endokrinen Potenzials von Bisphenol Alternativstoffen in umweltrelevanten Verwendungen. Abschlussbericht

Abstract

Bisphenol A (BPA) is mainly used as raw material in the production of plastic products. Due to its hormone-like effects in humans and other organisms, the use of BPA is closely connected to human health and environmental risks. Thus, there is high interest in substances with similar properties to BPA regarding its use in plastic products, however do not negatively influence the endocrine system of any organism. There are substantial data gaps regarding the molecular mode of action of many substitution candidates, which impede the assessment of their influence on the environment. A literature research was performed in order to identify environmentally relevant BPA substitution candidates. Furthermore, the interaction of these substances with a set of nuclear receptors was investigated, which might be responsible for the endocrine effects of BPA. The application of a number of biochemical and cell-based screening assays, the influence of these substances on the estrogen receptors α and β, as well as of the androgen receptor was determined
