1. Synthesis of indolocarbazoles, bisindoles and related sulfur containing systems
Abstract : This thesis is focussed mainly on the synthesis and reactions of various indolocarbazoles, bisindoles and related sulfur containing systems, all possessing structural features present in many biologically active, natural or synthetic compounds. In the first part, synthetic routes towards the planar, pentacyclic ring systems of indolo[2,3-c]earbazole and indolo[3,2-a]carbazole are described. READ MORE

2. Synthesis of indoles, bisindoles and indolocarbazoles : high affinity aryl hydrocarbon receptor ligands
Abstract : This thesis deals with the synthesis and reactions of indoles, bisindoles, indolocarbazoles and their derivatives. New methods for ring formation of planar, heterocyclic quinones, with the indolo[3,2b]carbazole or indolo[2,3-b]carbazole structures are described. READ MORE

3. Regulation of dioxin receptor function by procarcinogenic food-derived heterocyclic amines and indolocarbazoles
Abstract : Cooking of protein-rich food generates procarcinogenic heterocyclic aromatic amines(HCA) in amounts that range in the part per billion levels. The capacity of the two most prevalent HCA, PhIP and MelQx, to induce genetic alterations in vivo was determined using a short-term liver carcinogenesis model (RH-model) in rat. READ MORE

4. Application of metalation reactions for synthesis of sulfur/selenium-containing heterocyclic compounds
Abstract : This thesis deals mainly with the synthesis of various sulfur/selenium-containing heterocyclic compounds, many of which include structural features present in several biologically active molecules, with particular emphasis on compounds of synthetic importance, such as indoles, as well as other heteroaromatic species. In the first part, an efficient procedure toward synthesis of new 3-(arylthio)indoles based on reactions of aryl Grignard reagents or lithiated heteroaromatics with protected 3,3′-dithiobisindoles is described.

5. Dynamic regulation of aryl hydrocarbon receptor function and activity by different stimuli
Abstract : Cells have to sense and adapt to changes in their surrounding environment. Most of the cellular responses to environmental and developmental stimuli are mediated by PAS (Per-ARNT-Sim) proteins. A member of this family of proteins is the aryl hydrocarbon receptor (AhR), a ligand-activated bHLH transcription factor and E3 ubiquitin ligase. READ MORE
