Abstract:
PROBLEM TO BE SOLVED: To provide a method for identifying anti-HIV therapeutic compounds substituted with carboxyl ester or phosphonate ester groups. SOLUTION: Libraries of such compounds are screened optionally using the novel enzyme GS-7340 Ester Hydrolase. Compositions and methods relating to GS-7430 Ester Hydrolase also are provided. In one embodiment, this invention comprises following steps: (a) identifying a non-nucleotide prototype compound, (b) substituting the prototype compound with phosphonate-containing group to form a candidate compound, and (c) determining the anti-HIV activity of the candidate compound.

Abstract:
PROBLEM TO BE SOLVED: To provide an immunosuppressant with a reduced side reaction, having simple medication plan and/or is orally active. SOLUTION: The invention relates to the immunoregulatory phosphorus substituted compound, composition containing such compound, and therapeutic method that include the administration of such compound, as well as to processes and intermediates useful for preparing such compounds. The invention provides a new phosphonate-containing analogue of an immunoregulatory (immunosuppressant) compound. These compounds have usefulness of the related immunoregulatory compound but as the compounds have phosphonate group and typically provide accumulation of the phosphonate compounds in the cells. The compounds of the invention improve immunoregulation, pharmacokinetical property, oral bioavailability, efficacy or effective half value period of a long time in vivo. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide antiviral protease inhibitors.SOLUTION: The present invention provides compounds of formula I or a pharmaceutically acceptable salt, solvate, ester, and/or phosphonate thereof, compositions containing such compounds, and therapeutic methods that include the administration of such compounds. In another embodiment, the present application provides a method for treating HIV infections, which comprises a step of administering to a patient in need of such treatment a therapeutically effective amount of at least one compound of formula I, or a pharmaceutically acceptable salt, solvate, and/or ester thereof.
Abstract:
PROBLEM TO BE SOLVED: To provide a new derivative for reducing adverse effects of a pharmaceutical compound having kinase inhibitory actions and to provide a pharmaceutical composition comprising the derivative. SOLUTION: A phosphorus-substituted kinase inhibitory compound is obtained by introducing a phosphonic acid ester into a pharmaceutical having the kinase inhibitory actions (e.g. gefitinib, imatinib, erlotinib, vatalanib or staurosporine). The pharmaceutical composition comprising the compound and a therapeutic method are provided. Thereby, a phosphonate-containing molecule at a high concentration can be achieved in a target cell and the compound can be applied to various therapeutic formulations and treatments (various kinds of tumors, leukemias, inflammatory diseases, psoriases, transplant rejections, etc.).

Abstract:
PROBLEM TO BE SOLVED: To provide an anti-cancer phosphonate analogue, relating to compounds having anti-cancer activity. SOLUTION: By a method and a composition which make cells accumulate or hold a biologically active medicine in them, cell targeting can be done. The invention provides a new analogue of an anti-cancer compound. Such new analogues of anti-cancer compounds have all of the usefulness of the anti-cancer compounds, and optionally provide accumulation in cells described below. Furthermore, the invention provides a compound and a method for therapy of cancer or therapeutic activity to cancer. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide novel HIV protease inhibitors, pharmaceutical compositions thereof, processes for making the novel HIV protease inhibitors, and methods for inhibiting and treating an HIV infection.SOLUTION: The invention is related to compounds of formula I, or a pharmaceutically acceptable salt, solvate, ester, and/or phosphonate thereof, compositions containing such compounds.
Abstract:
PROBLEM TO BE SOLVED: To provide a new anti-inflammation agent such as a drug having improved anti-inflammatory property, improved pharmacological property, improved activity, improved bioavailability and improved effective half-life period in vivo. SOLUTION: The invention provides a conjugated material containing an anti-inflammatory compound linked to one or more phosphonate groups and its pharmacologically allowable salt or solvate. In one embodiment, the compound of the conjugated material is either one compound substituted with one or more A 0 groups and expressed by formulas 500-611. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a therapeutic antiviral preparation having improved pharmacological characteristics, a dosing regimen for a new antiviral compound not more troublesome than the conventional regimen, or an assay method determining the presence or absence of, or the amount of virus-inhibition. SOLUTION: The invention relates not only to a phosphorus-substituted compound having antiviral activity, a composition containing such compound and a therapeutic method including a process for dosing such compound, but also to a useful process and an intermediate for preparing such compound. The invention provides new phosphonate-containing analogues of the antiviral compounds. These analogues have all of usefulness of these parent compounds, and provide accumulation of them in cells described below, at need. The compounds of the invention can inhibit RNA-dependent RNA polymerase of retro virus or reverse transcriptase, and therefore, can inhibit duplication of virus. COPYRIGHT: (C)2007,JPO&INPIT
