Synthesis of Selective 5-HT7 Receptor Antagonists

Ehalt, Adam 18 November 2011 (has links)
The 5-HT7 receptor is the most recent addition to the 5-HT receptor family and has been linked to a variety of physiological and pathophysiological processes. Well established antide-pressant pharmaceuticals have recently been found to activate the 5-HT7 receptor, supporting the role of the 5-HT7 receptor in the antidepressant mechanism. The synthesis of potent selec-tive 5-HT7 receptor antagonists could afford a greater understanding of the 5-HT7 receptor function as well as lead to potential drug candidates. The synthesis of unfused biheteroaryl derivatives as 5-HT7 receptor ligands has been de-scribed within. These compounds have been tested for biological activity on the 5-HT6 and 5-HT7 receptors. 4-(3’-Furyl)-2-(N-substituted-piperazino)pyrimidines were found to be potent 5-HT7 receptor ligands. 4-(2’-Furyl)-2-(N-substituted-piperazino)pyrimidines have shown high se-lectivity for the 5-HT7 receptor over the 5-HT6 receptor.

Synthesis and characterization of novel cyclophanes from 5,5'-bi(isobenzofuran)

Fischer, Kristapher Edward, University of Lethbridge. Faculty of Arts and Science January 2005 (has links)
Isobenzofuran has since its discovery proven an important intermediate in the synthesis of novel organic compounds, due to its high reactivity in Diels-Alder reactions. This thesis details the synthesis, purification and characterization of cyclophane compounds derived from a novel analogue of isobenzofuran, 5,5'-bi(isobenzofuran). Because of the relative rarity of molecules containing multiple isobenzofuran units, 5.5'-bi(isobenzofuran) is an excellent candidate for study. Prelminary analysis of an additional novel analogue of isobenzofuran, 5.5'-bis(isobenzofuranyl) acetylene, is also presented. / x, 119 leaves : ill. ; 29 cm.
