    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: A method of preparing a 2'-fluoro compound of the formula ##STR1## where B is selected from the group consisting of purines and pyrimidines, both of which may be substituted, comprises reacting a compound of the formula II(a) or II(b) ##STR2## where R and R' are as defined in the specification with an acid halide under conditions effective to obtain a halide of the formula ##STR3## where X is a halogen. A silane of the formula B-Si (R").sub.3 where R" is as defined in the specification, is added to this product (III) under conditions effective to obtain a compound of the formula (IV) ##STR4## The compound of formula (IV) is reacted with a reagent selected from the group consisting of ammonia, BCl.sub.3 and ((C.sub.1 -C.sub.10)alkyl).sub.4 NF, under conditions effective to obtain the compound of formula (I). The compounds of formula (I) resulting from these methods exhibit anti-HIV activities and are useful for therapy against the HIV virus.
