Received: 4 January 2010; in revised form: 20 February 2010 / Accepted: 25 February 2010 / Published: 15 March 2010 Abstract: Equol, one of the main metabolites of daidzein, is a chiral compound with pleiotropic effects on cellular signaling. This property may induce activation/inhibition of the estrogen receptors (ER) or and therefore, explain the beneficial/deleterious effects of equol on estrogen-dependent diseases. With its asymmetric centre at position C-3, equol can exist in two enantiomeric forms (R- and S-equol). To elucidate the yet unclear mechanisms of ER activation/inhibition by equol, we performed a comprehensive analysis of ER and ER transactivation by racemic equol, as well as by enantiomerically pure forms. Racemic equol was prepared by catalytic hydrogenation from daidzein and separated into enantiomers by chiral HPLC.

I wish to extend my heartfelt gratitude to my supervisors; Prof. Abiy Yenesew, Dr. Solomon Derese and Prof. Isaiah O. Ndiege whose close supervision coupled with resourceful guidance/advice enriched me with the knowledge, skills and attitude resulting in the success of this research. I am grateful to the German Academic Exchange Services (DAAD) and the Natural Products Research Network for Eastern and Central Africa (NAPRECA) for financial support during my studies. I appreciate the help extended to me by Dr. Matthias Heydenreich of the University of Potsdam in spectroscopic/spectrometric analyses of some of the compounds reported in this thesis. Special thanks go to the Swedish Institute for sponsoring my research visit to the University of Gothenburg. I am indebted to my host supervisor, Prof. Máté Erdélyi, and the Halogen Bond Research Group of the Department of Chemistry and Molecular Biology, at the University of Gothenburg for his unwavering support and guidance in isolation and spectroscopic techniques and analysis. My sincere gratitude is extended to Dr. John P. Alao and Prof. Per Sunnerhagen of the Department of Chemistry and Molecular Biology at the University of Gothenburg for carrying out cytotoxicity assays.
