N7-DNA: Base-Pairing Properties ofN7-(2′-Deoxy-β-D-erythro-pentofuranosyl)-Substituted Adenine, Hypoxanthine, and Guanine in Duplexes with Parallel Chain Orientation
Simple, Chemoselective Hydrogenation with Thermodynamic Stereocontrol
摘要:
Few methods permit the hydrogenation of alkenes to a thermodynamically favored configuration when steric effects dictate the alternative trajectory of hydrogen delivery. Dissolving metal reduction achieves this control, but with extremely low functional group tolerance. Here we demonstrate a catalytic hydrogenation of alkenes that affords the thermodynamic alkane products with remarkably broad functional group compatibility and rapid reaction rates at standard temperature and pressure.
The compound 9-B-D-arabinofuranosyl-2-amino-6-methoxy-9H-purine along with its 5'-acetyl and 5'-(4-methoxy-4-oxobutyryl derivatives are disclosed as inhibitors of Varicella Zoster virus (VZV).
The present invention relates to certain substituted purine arabinosides and their pharmaceutically acceptable derivatives especially esters and their use in the treatment and prophylaxis of varicella zoster virus and cytomegalovirus infections. The invention also includes pharmaceutical formulations and processes for the preparation of such compounds.
This invention relates to certain 6-substituted 2ʹ,3ʹ-dideoxypurine nucleosides and pharmaceutically acceptable derivatives thereof and their use in the treatment and prophylaxis of HIV infections.

Methods of producing single-stranded deoxyribonucleic acids (ssDNAs) are provided. Aspects of the methods include generating a double stranded deoxyribonucleic acid (dsDNA) and then selectively degrading one strand of the dsDNA to produce a ssDNA. ssDNAs produced using methods of the invention find use in a variety of applications, including genomic modification applications. Also provided are compositions, e.g., kits, that find use in practicing various embodiments of the invention.
