Abstract: This invention provides a class of compounds which are useful for specifically inhibiting cyclin-dependent kinases. This class of compounds finds use in treating diseases resulting from inappropriate activity of cyclin-dependent kinases, including cancer, viral infections (e.g., HIV) neurodegenerative disorders (e.g. Alzheimer's disease), and cardiovascular disorders (e.g. atherosclerosis). Moreover, certain members of this class are particularly useful for inhibiting cyclin-dependent kinase 7 and are especially useful for the treatment of breast cancer.

Abstract: This invention provides highly regioselective and stereoselective processes for preparing synthetic nucleosides. A process for the preparation of synthetic nucleosides is provided that comprises a) preparing a bicycloamide derivative, b) reacting the bicycloamide derivative with a nucleic acid base or heterocyclic base or salt thereof in the presence of a transition metal catalyst to form a cyclopentenecarboxamide, and c) cleaving a carboxamide group from the cyclopentenecarboxamide to form the synthetic nucleoside. The processes according to the invention can be used for the synthesis of a variety of anti-viral agents, including Abacavir, Carbovir, and Entecavir, as well as derivatives thereof.

Abstract: The present invention discloses a method for treating HIV that includes administering ?-D-D4FC or its pharmaceutically acceptable salt or prodrug to a human in need of therapy in combination or alternation with a drug that induces a mutation in HIV-1 at a location other than the 70(K to N), 90 or the 172 codons of the reverse transcriptase region. Also disclosed is a method for using ?-D-D4FC as “salvage therapy” to patients which exhibit drug resistance to other anti-HIV agents. ?-D-D4FC can be used generally as salvage therapy for any patient which exhibits resistance to a drug that induces a mutation at other than the 70(K to N), 90 or the 172 codons.

Abstract: A process for the resolution of a racemic mixture of nucleoside enantiomers that includes the step of exposing the racemic mixture to an enzyme that preferentially catalyzes a reaction in one of the enantiomers. The nucleoside enantiomer (?)-2-hydroxymethyl-5-(5-fluorocytosin-1-yl)-1,3-oxathiolane is an effective antiviral agent against HIV, HBV, and other viruses replicating in a similar manner.

Abstract: The present invention provides synthetic methods and compositions for treatment of autoimmune and anti-inflammatory disorders comprising administering an effective amount of a derivative of triptolide alone or in combination or alternation with other anti-autoimmune or anti-inflammatory compounds.

Abstract: Provided are cyclobutyl nucleosides and methods for their use in treatment of infections including Retroviridae (including HIV), Hepadnaviridae (including HBV), or Flaviviridae (including BVDV and HCV) infection, or conditions related to abnormal cellular proliferation, in a host, including animals, and especially humans.

Abstract: The invention provides compounds, pharmaceutical compositions and methods of use of certain compounds that are antagonists of the chemokine CXCR4 receptor for the treatment of proliferative conditions mediated by CXCR4 receptors or for the treatment of viral infections. The compounds provided interfere with the binding of SDF 1 to the receptor. These compounds are particularly useful for treating or reducing the severity of hyperproliferative diseases by inhibiting metastasis, or for reducing entry of HIV in to a cell while not reducing the capacity of the stem cells to proliferate. The compounds may be useful for long term treatment regimes.
