Book excerpt: While the bromination of aromatic compounds is a well-researched topic, AQ and hydroxy substituted AQ derivatives, with two carbonyl groups acting as strong deactivators for electrophilic substitution, are notoriously difficult to brominate.11 Although there are well defined ways to brominate an AQ or hydroxy substituted AQ dating back to 1921,12 in order to synthesize more complex AQ derivatives, a method for halogenating AQ derivatives already bonded to more complicated or unstable functional groups is needed in order for the compound to carry out desirable activities. This represents an area of great need in research. The purpose of this paper therefore is three-fold. First, it sheds light on the properties of AQ and AQ derivatives, explaining previous uses of it. Next, reactions with a brominated 1-mono-substituted AQ to add another functional group without compromising the AQ derivative itself are summarized. Finally, various methods of performing such a reaction are evaluated, and experimental findings of some attempts performed in lab at Liberty University Department of Biology and Chemistry are reported.

This object was only partially attained but the reaction tried proved interesting and the products obtained appeared worthy of study, so the investigation was shifted from its original purpose and extended in other directions.

Abou-Elkhair and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthraquinone (AQ) has been used in electron transfer studies in DNA. The focus of this dissertation is the synthesis of conjugates between AQ derivatives and 2'-deoxyadenosine (dA), which can be used to induce adenine oxidation in DNA. Different AQ derivatives were attached to dA via ethynyl or ethanyl linkers. If incorporated into DNA, these short linkers should enable regiocontrol for electron transfer from adenine within the DNA duplex structure. The challenge in working with anthraquinone-2'-deoxynucleosides conjugates is that they and their intermediates are insoluble in water and only sparingly soluble in most organic solvents. A strategy used to overcome this problem was the use of either tert-butyldiphenylsilyl (TBDPS) or 4',4-dimethoxytrityl (DMTr) 5'-protected deoxynucleosides as starting materials. A water-soluble, ethynyl-linked AQ-dA conjugate with a 3'-benzyl hydrogen phosphate was synthesized using DMTr protection. The DMTr group was not stable to the hydrogenation required to make the ethanyl-linked AQ-dA conjugate with 3'-benzyl hydrogen phosphate. Hence the latter was synthesized starting with the TBDPS protecting group. Both of these syntheses were based on the Pd coupling between ethynylanthraquinone and 8-bromodeoxyadenosine derivatives. New conjugates between AQ and A, in which the AQ moieties have been modified with formyl, trifluoroacetyl and methyl ester groups as electron withdrawing substituents were also synthesized. The synthesis of these AQ-dA conjugates was based on Pd coupling between bromoanthraquinone and 8-ethynyldeoxyadenosine derivatives. This route avoided the use of ethynylanthraquinone derivatives that had extremely low solubility and photoinstability. Other anthraquinones with electron withdrawing groups (which should provide enhanced driving force to enable respective AQ derivative to oxidize adenine) were synthesized as models. Cyclic voltammetry showed that the conjugate with the two ester groups and ethynyl linker was the most easily reduced of the derivatives synthesized. Conjugates between AQ and dU were also synthesized. Those conjugates can potentially be used to oxidize guanine or adenine or they can be used as a deep trap for an electron in reduced DNA.
