The Pd0/Cu1 catalyzed cross-coupling of terminal alkynes onto peptide nucleic acid monomers or submonomers bearing iodinated nucleobases has been utilized as a route to base-modified oligomers. Both 5-iodouracil and 5-iodocytosine derivatives undergo the cross-coupling to give the expected products in

As part of our ongoing investigation of the synthesis of biologically interesting 2'-modified-4'-thionucleosides, we synthesized 2'-deoxy-2'-fluoro-4'-thioarabinofuranosylpyrimidine and -purine nucleosides, and evaluated their antiviral and antitumor activities. In the pyrimidine series, beta-anomers of 5-ethyluracil, 5-iodouracil, 5-chloroethyluracil, and 5-iodocytosine derivatives showed potent

The virally encoded integrase protein carries out retroviral integration, and to do so, it must make specific interactions with both viral and target DNA sequences. The retroviral integrase has three domains: an amino-terminal region of about 50 amino acids that
