A resin-capture and release strategy for making combinatorial 2,6,9-trisubstituted purine libraries is demonstrated by capturing N9-derivatized purines at the C6 position with a thio-modified polymer. The C2 fluoro group is subsequently substituted with primary and secondary amines followed by thioether

2-Nitropropane, an industrial chemical and a hepatocarcinogen in rats, induces aryl sulfotransferase-mediated liver DNA and RNA base modifications [Sodum, R. S., Sohn, O. S., Nie, G., and Fiala, E. S. (1994) Chem. Res. Toxicol. 7, 344-351]. Two of these modifications
6-(p-Hydroxyphenylhydrazino)uracil (H2-HPUra) is a selective and potent inhibitor of the replication-specific class III DNA polymerase (pol III) of Gr+ bacteria. Although formally a pyrimidine, H2-HPUra derives its inhibitory activity from its specific capacity to mimic the purine nucleotide, dGTP. We

A convergent synthesis of adenosine A2a agonist 1 in the form of its maleate salt 2 was achieved. The key step in this approach was the highly selective 9beta-glycosylation reaction between 2-haloadenines or an N(2)-alkyl-6-chloroguanine and a D-ribose derivative containing
The survival times of patients with advanced colorectal cancer (CRC) have increased due to the introduction of chemotherapy involving irinotecan and cetuximab. However, further studies are required on the effective pretreatment methods for identifying patients with CRC who would respond
