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

Two series of selective inhibitors of herpes simplex virus types 1 and 2 (HSV1,2) thymidine kinases (TK) have been developed as potential treatment of recurrent virus infections. Among compounds related to the potent base analog N2-[m-(trifluoromethyl)phenyl]guanine (mCF3-PG), none was a

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

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
