摘要:
2′ and 3′-Prodrugs of 1′, 2′, 3′ or 4′-branched β-D or β-L nucleosides, or their pharmaceutically acceptable salts and derivatives are described, which are useful in the prevention and treatment of Flaviviridae infections and other related conditions. These modified nucleosides provide superior results against flaviviruses and pestiviruses, including hepatitis C virus and viruses generally that replicate through an RNA dependent RNA reverse transcriptase. Compounds, compositions, methods and uses are provided for the treatment of Flaviviridae infection, including HCV infection, that include the administration of an effective amount of the prodrugs of the present invention, or their pharmaceutically acceptable salts or derivatives. These drugs may optionally be administered in combination or alteration with further anti-viral agents to prevent or treat Flaviviridae infections and other related conditions.

摘要:
There are disclosed novel compounds of formula (Ia) or (Ib) wherein R1, R2, R3, R4, X and Y are as defined in the specification, and pharmaceutically acceptable salts thereof; together with processes for their preparation, compositions containing them and their use in therapy. The compounds are inhibitors of the enzyme MPO and are thereby particularly useful in the treatment or prophylaxis of neuroinflammatory disorders.
摘要:
The invention is based on the discovery that compounds of Formula I are unexpectedly highly potent and selective inhibitors of the adenosine A1 receptor. Adenosine A1 antagonists can be useful in the prevention and/or treatment of numerous diseases, including cardiac and circulatory disorders, degenerative disorders of the central nervous system, respiratory disorders, and many diseases for which diuretic treatment is suitable. In one embodiment, the invention features a compound of formula I:
摘要:
The present invention provides novel nucleoside and nucleotide derivatives that are useful agonist or antagonists of P1 and 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 cycloalkyl 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:
This invention relates to purine derivatives, to processes for their preparation, to compositions containing them and to their use. The present invention provides compounds of formula (I) wherein R1, R2, R3, R9, R9a and Y are defined in the description. More particularly, the present invention relates to the use of purine derivatives in the treatment of a variety of viral infections and immune or inflammatory disorders, including those in which the modulation, in particular agonism, of Toll-Like Receptors (TLRs) is implicated. Accordingly, the compounds of the invention are useful in the treatment of infectious disease such as Hepatitis (e.g. HCV, HBV), genetically related viral infections, inflammatory diseases such as asthma and arthritis, and cancer.
