Nucleosides crystal structure

The purine nucleoside crystal structures adenosine, inosine, and guanosine provide less reliable data from the hydrogen-bonding point of view. This is particularly true of the guanosines, where only four structures can be reported. [Pg.281]

Several C-nucleoside, isonucleoside, thionucleoside and hexose nucleoside crystal structures have been reported this yean p-D-arabinosylcarbouridine 80 and oxazofurin 81, isodideoxyadenosine 82,1 7-P-D-glucopyranosyladenine 83, and the 4-thionucleoside derivative 84 (structural details and relationship to activity are discussed in Chapter 20). ... [Pg.328]

The mechanism of carcinogenesis by PAHs is believed to involve alkylation of an informational macromolecule in a critical, but at present unknown, manner. Such an interaction with a protein has been modelled by alkylation of a peptide this showed a conformational change occurred on alkylation. It has not yet been possible to study the structure of DNA alkylated by an activated carcinogen this is because DNA is a fiber and the structural order in it is not sufficient for a crystal structure determination. However the crystal structures of some alkylated portions of nucleic acids are described, particularly some nucleosides alkylated by chloromethyl derivatives of DMBA. In crystals of these alkylation products the PAH portion of the adduct shows a tendency to lie between the bases of other nucleoside... [Pg.130]
