This volume looks in detail at the chemistry and carcinogenicity of the
cyclopenta[a]phenanthrenes; these are fully aromatic (i.e.
dehydrogenated) derivatives of physiologically important hormones, the
steroids and some have been shown to be powerful carcinogens in animal
models. Others have been found to be of widespread occurrence in the
environment where they are probably derived from plant steroids. This
book covers all aspects of this class of compounds including their
chemical syntheses and chemistry, occurrence, physical and spectral
properties, metabolism, carcinogenicity and mutagenicity. It also
outlines how steroid biochemistry indicates the way in which these
molecules might be formed in vivo as a result of incorrect steroid
metabolism and ends with a call for the application of powerful modern
analytical techniques to the problem of whether they do occur in this
way and are a cause of human cancer.
