    摘要: The present invention provides novel nucleoside and nucleotide derivatives that are useful agonists or antagonists of P1 or P2 receptors. For example, the present invention provides a compound of formula A-M, wherein A is modified adenine or uracil and M is a constrained cycloalkyl group. The adenine or uracil is bonded to the constrained cycloakyl group. The compounds of the present invention are useful in the treatment or prevention of various diseases including airway diseases (through A2B, A3, P2Y2 receptors), cancer (through A3, P2 receptors), cardiac arrhythmias (through A1 receptors), cardiac ischemia (through A1, A3 receptors), epilepsy (through A1, P2X receptors), and Huntington's Disease (through A2A receptors).

    摘要: The embodiments described herein concern 5-substituted pyrimidine derivatives of conformationally locked nucleoside analogues and to the use of these derivatives as anti-viral and anti-cancer agents. The compounds are of the formula: wherein B is uracil-1-yl or cytosin-1-yl having a 5-substituent selected from halogen, alkyl, alkenyl, and alkynyl, with the proviso that where B is uracil-1-yl, the 5-substituent is not methyl. The compounds are useful in the treatment of Herpes simplex virus (HSV).

    摘要: 5,6-dihydro-5-azacytidine phosphoramidite is useful in the synthesis of oligonucleotides and DNA containing dihydro-5-aza- and 5-azacytosine bases. The modified oligonucleotides which contain 5-azacytosine residues at specific sites can be used to determine the mechanism of selective gene activation and the relationship existing between the presence of the triazine base and inhibition of DNA methylation.
